VPN connection grabs multiple IP addresses - Networking

Hi,
I'm having trouble with my MDA Vario III / HTC Kaiser running WM6.0 when making a connection to my office VPN (PPTP). I have to connect to the VPN to access the Exchange server. However, my IT people tell me that the phone is grabbing multiple IP addresses, so many that they have to eventually kill my access to the VPN.
I stopped using Direct Push, but even when the phone is scheduled to connect every 15 mins, the problem still occurs.
Can anyone suggest what's going here, and what the solution might be?
Thanks,
Jon.

Something seems to be wrong with your networking drivers on your phone. Mine doesn't grab multiple IP addresses just one and it keeps getting the same one in accordance to lease time settings on my DHCP Server and Firewall.

Thanks - your reply set me thinking, so I dug into the registry. The key relating to the VPN connection had 'EnableDHCP=0', this despite the fact that the connection is set to 'Use server-assigned IP address'. I've manually set it to 1, and I'll test tomorrow when I can talk to my IT people.

This is a real headache. The problem seems to be that the VPN connection refuses to use DHCP, even when I toggle the registry setting that I mentioned. If anyone has any ideas I'd like to hear them.

XDAIIi wi-fi problem

Hi all. I looked at several wi-fi posts on here, but couldn't find anything related to my problem.
I'm beginning to suspect that it's because of something stupid I'm doing, cos it really should be working...
Anyhoo ...I have a wireless router at home, and it's serving 3 PCs with DHCP IP addresses, and an internet connection. I have no issues with it.
What I'm trying to do now is get my shiny new XDAIIi to connect, so that I can have the damn thing on the internet. So far, no luck.
Now, I have got the XDA to detect my SSID. It detects all the settings, and tells me it's connected. I even have a signal strength bar on it which reads about 50%.
However, when I set it to pick up a DHCP address it stubbornly refuses, remaining with a "I can't see a DHCP server" 169.x.x.x address.
I've tried reserving an address on the router and allocating it to the MAC address of the XDA, and manually setting the XDA to have that IP address, entering my router as the gateway, and even entering 2 valid DNS server IPs from my ISP into the name server entries. Still nothing. It says it's connected with the IP address I allocated, but I have no net connection, and I can't ping that address from any of my PCs.
All the while the status screen on the router tells me that the device, with it's MAC address, is connected to the router fine.
Surely this has to be something simple. I have set up all the clients and router for my network, and the settings on the XDA are pertty much the same, and really SHOULD be working.
I'm kinda at my wits end.
So basically any suggestions or advice, or anyone with similar experiences please get in touch, cos I'm struggling to see what I've done wrong, and it's giving me an ulcer.
Many thanks in advance.

3COM WAP (3CRWE454G72) - XDA IIi WIFI Problems
Hi Jess,
I very much share your frustration.
I have a 3COM WAP (3CRWE454G72) which has served me well. I have a few machines at home working from it. At work we have 20+ machines working from the same model (older firmware).
My specs are as follow:
3C number 3CRWE454G72
Software version 1.03.07A
Boot loader version 1.00.00
Wireless version V1.0.2.1
Hardware version R01A
Don't have the office one's specs here at the moment ...
At work I can get an IP address (there's a windows DHCP server) .. AND I can ping google and traceroute to google. BUT, XDA IIi doesn't seem "know" that it's connected (e.g. network settings shows the WAP as available, but not connected). SKYPE even works!! But nothing else, no IE, no Terminal Services Client, no Avant Go, no network ActiveSync. They all say that the is no network card configured (but with vxUTIL, vxIPCONFIG, etc). I can see ALL the IP details from the DHCP server.
At home it's worse. I can't even get it to connect to the WAP (either with WEP 128, WEP 64 or encryption turned off). As I'm not even getting an IP address at home from the WAP's DHCP server, I've built a new DHCP server on my one linux box and it works for all my machines ... now I can actually trace requests from devices for IP's ... and the XDA IIi never requests an IP address. Which tells me that it's not even getting through the first stages of connecting with the WAP (again tried WEP, NO WEP).
To make things worse. I have been able to connect to some open WAP's in the neighbourhood ... everything functioning normal.
I'm losing the will to live here also ... ;-)
Wolfie
the plot thickens...
Hi Wolfie.
Well, at this end I seem to have more news.
By removing all WEP encryption and removing the MAC address access restriction I had enabled, I got the XDAIIi online, and all was working.
I then enabled the security a step at a time, and at each step updated the configuration on the handheld, and it still all worked. I was so pleased.
)
However this morning I have come to put the thing online again, and once again it refuses to pick up a DHCP address.
I tried my process again, and this time it wont work.
It definitely seems that it's the encryption that's stopping it, but I can't get it working this morning.
When I disabled everything I managed to get it online, but then re-enabling the security killed it and I can't get it to come online again.
SIGH
Oh well, I will try again later. Fussy thing. Anyone ever manage to solve this ??
Jess
have u tried soft reseting the device and retrying, sometimes that cures these hiccups

WIFI WOES
Jess, thanks for the reply. There's hope. ;-)
I have tried your approach yesterday. However, to no avail. At home I completely opened my WAP, e.g. any MAC, no WEP/WPA, etc. But still nothing. When I look at my log files on the WAP. I can see plenty of entries coming from my XDA IIi ...
04 min(s) 41 sec(s) after system power on : Wireless MAC address 00:09:2D:14:C9:F2 has connected with the device
04 min(s) 43 sec(s) after system power on : Wireless MAC address 00:09:2D:14:C9:F2 has connected with the device
04 min(s) 45 sec(s) after system power on : Wireless MAC address 00:09:2D:14:C9:F2 has connected with the device
04 min(s) 46 sec(s) after system power on : Wireless MAC address 00:09:2D:14:C9:F2 has connected with the device
04 min(s) 48 sec(s) after system power on : Wireless MAC address 00:09:2D:14:C9:F2 has connected with the device
04 min(s) 50 sec(s) after system power on : Wireless MAC address 00:09:2D:14:C9:F2 has connected with the device
... and it just goes on and on and on .... while trying to connect.
At the same time in all connections attemps, I don't get a single entry in my DHCP servers log saying that my XDA II attempted to connect.
Jim: I've tried hard resets, soft resets, O2 Active installed, Corporate mode, pretty much everything my single brain-cell can come up with. ;-)
The thing is definitely a little fiddly indeed ...
The search goes on ...
... anybody out there got their XDA IIi working with WIFI using DHCP and WEP or WPA?
Did you ever get this working?
I have a shiny new XDAIIi and have been trying to get connected via my Cisco Aironet 1200 WAP. The device happily detects my network, accepts the WEP key fine (complains if I enter the wrong key so I know it's communicating) but refuses to pick up an IP address. The Wireless LAN Manager just sits there "Scanning network..."
I firmly belive I'm just missing something but...........
Any help gratefully received :?

I got my QTek 2020i today and for the life of me I can't get it to connect to the internet using my wifi connection @ home
I also have a 3COM router 3CRWE754G72-A and I have my home pc connected to this and also occassionally my work PC - both with no probs.
I can get the qtek to connect and I get a 50% signal strength and I can view an IP address and everything looks good but I can't seem to setup a "Connection" as required by IE?
This is what I get:
"Cannot connect with current connection settings. To change your connection settings, tap Settins"
I tap settings and I get this:
My ISP
Add a new modem connection
My ISP
Add a new modem connection
Add a new VPN server connection
Set up my proxy server
I've gone into each of these and had a "play" but I still can't get the bloody thing to work :evil:
Can someone PLEASE help as this is starting to drive me mad! - I'm not giving up easily...I've been trying to get this to work for a good 4 hours now and I can't find anything in the manual or on the web that helps...this post was the closest I could fine >>> hence the bump!

have you try to configure the network cards in the connection setting and set the internet using the tiacxwln Compatible Wireless Ethernet?

Okay, I can get the connection to read "connected" via the Wireless Lan Manager and I can get an IP address - which is totally different to all the other PC's that use my wifi connection - they're all 192.168.1.x whereas this is very different? - the address that I get isn't even the same as the IP Address of my router - I have a static IP address so I know this isn't changing???
Also, when I view the network card page I see the following:
Configure Wireless Networks
Add New...
3Com Available
I can click on this and view the settings for it or I can hold-click and get the option of connecting. If I do this, it just says "connecting"; it never actually says "connected"?
Anyone know where I can get a walkthrough for this?

3 Com Routers
Hi, DotN
I put a 3Com router in my local pub.
I have no problem connecting to it and solving the usual pub talk problems with it.
If you are getting a connection but your IP address starts with 169.254 then I would say you have a WEP problem. The software only appears to check for incorrectly formatted WEP keys, so either turn it off or make sure you enter the correct key. When selecting connect to a router the message sticks on connecting, come out of the screen and go back in after about 30 secs. Check you ip address. I have had some issues with GRPS trying to connect, but they seem to go away after a couple of hides.
I have to say that I am not over the moon with my XDA2i, but the wifi part has worked pretty well for me.

Hi Paddy
Thanks for the info. You're bang on with the IP Address!...169.254.x.x
So what encryption can I use?
I've deffinately got the correct password but it's obviously not working
Cheers
Wayne
Hi again
Okay, I've just checked the encryption and I'm using WPA-PSK authentication with TKIP encryption.
Is this what you had?

Are you using a password or 13 Hex pairs, I use the pairs. Try either turning wep of completely or entering 26 1s. Remove your setting for your ap in Configure Wireless Networks screen then reconnect.
Let me know what happens

Okay, I've basically removed all security from my wifi setup. I live in the middle of nowhere so it's not a problem - although once I get the wifi working I'll try and get the security going again.
I still can't get a connection
...stop the press!
Okay, I had a thought...maybe I can't connect because of the speed?
the router is a 11g but supports 11b (which is what the QTek 2020i/XDA IIuses) - sure enough, I had the 11g only option selected - DOH!
removed that and I've managed to connect without security.
I assume this was my problem all along...will now stick the security back on and try again
Thanks again Paddy
Cheers
Wayne
Update: I've now managed to get the wifi working with WPA-SPK authentication using TKIP encryption
all along it was simply a case of me having the speed on the router set above what the PDA was capable of! I'd set this ages ago when I first setup my wlan and had forgotten about it cause everything I use is 11g

Doh!...nope, not working again...back to the 169.254.x.x problem.
It's obviously to do with the encryption this time. I'll try some other variations - at least I know that it can work :roll:

Ouch......
No hard feeling, glad you found the problem
Paddy
bump!
pretty much same prob!
i can get an ip, have to check what it is, it tells me its connected on the scanning network page but on the other bit it tells me its available or connecting but never connects!
i've turned wep off and still no joy!
its really starting to drive me mad!
please please someone help
Take a read back through the last lot of posts between myself and MacPad - I think you'll find the answer there.
For me, I had to totally disable my security and everything else - I could then connect. Once I'd done that, I managed to use WEP with a 26 digit key - start by using something like "0" 26 times...make sure u count as u type them zero's in though as if u get it wrong it won't work!
apart from that, not sure what to say. If you're getting the 164.x.x.x ip address though then as MacPad said, it's to do with the security.
I would mention that the XDAIIi/Qtek 2020ii use 11mbps wifi (b) and not 54mbps (g) so make sure u've got ya router configured to allow both types of connection...this eventually turned out to be my main problem - doh!
Cheers
Wayne
ok now im home ive re-read and done the things mentioned. with a completely unsecure connection i can get a connecation, but the moment i use any kind of encryption (im using wep 64bit, but tried 128bit as well) no matter what key i use i get a split second of connection then its gone!
firewall is not on either.
any ideas??
thank for the suggestions guys im finally progressing

VPN won't work with a 10.x.x.x network

Hi,
I have a little problem that I am sure there must be an easy solution to!
I have set up a VPN on my Universal to connect to work. The problem is that my work's VPN server allocates me an ip address in the 10.x.x.x address range. All servers that I need to access behind the VPN have addresses in this range as well. Unfortunately, my ISP (T-Mobile UK), also allocates an address in the same range. Therefore, whenever I try to acccess a server at work, WM5 suffers confusion since it doesn't know whether to route the message through the VPN or directly out to the internet through the cellular modem.
I have been able to verify that the VPN thing works if my work network was on a different network address since initially, I was unable to VPN into my PC at home for the reason described above. I changed the ip addresses of all machines on my home network and now everything works fine at home.
Unfortuantely, I am unlikely to convince the IT people at work to change the address of all their machines. Similarly, I don't think I will have much success with T-Mobile and so is there anything I can change at my end to avoid this problem?
Thanks in advance for any help.
Mark
Narrowing the ip address may help, eg 10.0.0.1 is different to 10.1.0.1.
are you using this over wifi or gprs? if the phone provider is involved, I assume its gprs.
you could try and esablish your ip address as fixed rather than part of the pool, so the it guys assign a range for remote connections as say 10.0.0.100 to 10.0.0.150 as remote dial in connections, thus giving you a separate number.
the best way though I would have thought is for you to a fixed ip address known to you and the servers, and then hard type the ip address as your vpn settings, then establish that ip address as part of the exceptions settings.
in order to use exceptions though you have to know the range, or the exact ip address you will be assigned, and must be different to your telco.
not much of a solution, just some suggested areas to look at.
cheers

hi guys, just out of curiosity what software are you using for VPN? on my laptop my company has installed cisco vpn, does it need to be a cisco vpn for wm5?? :?
From bad to worse...
Thanks for the reply Simon.
Unfortunately, I just went to try out some of your ideas and discovered that I can't get the VPN to connect at all now. It used to connect OK but then have routing problems whenever I tried to access anything. And my home VPN worked perfectly. Now, I can connect to neither.
I simply switched over to an O2 sim and with minimal configuration changes could verify that my setup still works OK and so it must be something to do with T-Mobile blocking ports. They weren't blocked yesterday!!!
Yesterday I "upgraded" my GPRS account from T-Mobile's Web'N'Walk to Web'N'Walk Professional and now I find I have this problem. Is this just a coincidence, or could it be that the Pro version has more severe restrictions than the consumer version?
I have emailed Customer Services to see what they have to say.
I will post back when I get a reply from T-Mobile.
mstar, I am no VPN expert, but for me, using a Windows XP hosted PPTP VPN it works after a fashion (above problems excepted!). I am using the VPN client built into Windows Mobile 5. I think you stand a good chance of getting it working using the built-in client.

I've heard on the grapevine that T-mobile have explicitly refused certain types of traffic on the web-n-walk
VOIP is the biggy...
I was seriously thinking about getting signed up - but no point if IPSEC is a prob, as well as VOIP.
Not sure how they can tell it's Skype traffic :?

An Update
An update on my VPN problem. Yesterday after total failure to get the VPN to connect, I emailed T-Mobile customer services.
Although they have not replied, when I tried it this afternoon I found that it was working again as before even though it had not been working first thing this morining. Of course I have not changed anythng at my end to cause it to break and then start working again (but they all say that, don't they!).
So, I don't know whether this was just a momentary fault, or whether T-Mobile have changed something to re-enable the VPN ports for me. I can now VPN in to my home PC, but the problem connecting to my work VPN with the 10.x.x.x address remains.
So, Sikkutz, depending on the address of the remote network, you may or may not be able to get a VPN to work using T-Mobile's Web'N'Walk.
By the way, my VPNs both use Microsoft's PPTP and not IPSec and so there may be different issues with that protocol.
I have discovered that O2 provides a separate acccess point, vpn.o2.co.uk, that causes a public ip address to be allocated to the device, ie not on the 10.x.x.x network. It would seem that this is designed to address this very problem. Does anyone know if T-Mobile can provide something similar?

There must be a solution
Hi!
I have the same problem with my Qtek 9000 (VPA IV). I can connect to my VPN Gateway but the routing into LAN failed. I get a 10.x.x.x address from Vodafone Germany and my LAN uses 10.98.8.X. :-(
But there must be a solution! My previous Qtek 9010 (VPA III) had the same problem, but it was able to route between the 10.-networks after a firmware-upgrade to version 1.40.01! But I don't no why!
What was changed in firmware to enable routing???
Daniel
i have the same issue aswell, I am reluctant to change the IP range of my machines as that usually causes trouble for the servers
Any other ideas?
Thanks
maybe stupid thing, but did you guys try dna forwarding (that is what I use from home office, not on pda to be honest..
Maybe I just did not get your point....
What kind of VPN server do you use? I'am using a Cisco PIX and use a PPTP VPN almost everyday. I can use the 10.1.x.x network at the location the PIX is located (this PIX is directly connected to the 10.1.x.x network).
I can't however use any of the remote offices using 10.2/10.3.x.x etc.
This is becaus of the lack of routing abilities in the PPTP implementation.
With an IPSEC tunnel (additional software needed) the remote offices can be reached without any problems.
I know that some IP implementation disallow routing between a public address and any 10.x address. To solve this you could give your VPN clients an address from a 10.x subnet .
hi sorry been away awhile,
I use the routing and remote admin snapin of Windows server 2003 to manage my VPN, I can connect fine using the phone as a modem with my notebook but as soon as I try accessing any URL/resource on my network it fails, e.g. we have a intranet site on http://servername but it wont open this up.
Any Ideas?

VPN driving me mad!

Over the last year I have tried many times to set up my Windows Mobile devices to connect over VPN and then use RDP to manage my clients' sites. To date I have never managed to get it to work. My config is as follows :-
Within Start \ Settings \Connections \ Advanced \ Select Networks
Programs that automatically connect to the Internet use MY ISP
Programs that automatically connect to a private network "My Work Network"
a VPN is configured under "My work network" and the device can connect to this and using vxutil I can ping the server I wish to RDP to - 172.17.3.3
Supposedly the important bit is to add the exception under "Work URL exceptions", I have added 172.17.3.3 in here.
Once the VPN is established if I enter 172.17.3.3 within IE or Terminal Services CLient the VPN connection is still dropped.
If I enter this IP address without connecting the VPN first then the device will not connect the VPN automatically.
If I enter a non qualified domain name such as ids-vs then the VPN is connected but the name is never resolved.
Can anyone shed any light on this, if I could use a local lmhosts file on the device as with XP then I may be able to work around the above. It appears to me though as though the exceptions list is never processed. I did a hard reset last night just in case, but this has made no difference.
I cannot believe that the above can be so complex.
I am using a HTC Tytn and using t-Mobile in the UK.
Any help greatly appreciated since it is driving me totally mad!
I would love to figure that out.
I was trying to connect to my pc at home like this and suffered from all the same symptoms your having. In the end I gave up, mainly 'cause someone told me that I needed another type of data plan to have vpn (at the time I had the $29.99USD plan) in other words it might be your plan, or something to do with the proxies or something, I hope someone would find out what you need to do in order to get this to work.
It's strange, looking around the web there are loads of people that struggle with the setup, but most seem happy once they are told to add the server name or IP address in the exceptions list.
I have ruled out the data plan since I can establish the VPN connection and can see it authenticate on the other end, as well as being able to ping the server on the work network from the phone.
I have just opened a support call with Microsoft as well, but I am not holding out much hope since I think they will point me at HTC. Assuming HTC ever responded they will just point me back at Microsoft!
Well it would be cool if they could help you, I tried everything myself and zilch. I could also establish a connection but as soon as I would try to access a file on my pc it would disconnect. I would try to help you out experimenting on my side again, but I changed my router to a cheap piece of $h.. and now I can't access my pc via vpn..... I really need to get a decent router
This may sound stupid, but I could swear someone told me something about the speed of the connection. If the connection speed is too low then DNS would fail, although that wouldn't explain why we are able to establish a connection, but not access anything else.
OK, I have made quite a bit of progress :-
1) I was using a cab file to configure T Mobile settings on the phone. This was somehow configuring the exceptions list to be ignored. Hard resetting the phone, installing this CAB the problem remained. Hard Resetting the phone and setting up GPRS manually - everything worked.
2) There is a fault with Windows CE 5 routing over VPN - the subnet information is ignored. Hence for example, if your GPRS provider give you a NAT 10.x.x.x ip address and your corporate network uses 10.x.x.x then you can never route to your corporate network.
And what cab file is that? do you know if it's on the extended roms for the t-mo roms? Glad to see your making progress, keep it up.
It was a Cab file for the Tmobile settings. It either came from these forums or over at modaco, can't remember which.
VPN
I was able to successfully use the Movian VPN to connect to my work using my XDA2.Worked fine for 2 years. Apologies, but I can't help with the settings and my work migrated to an M-notes server so I was able to connect without a VPN.

Multiple IP addresses

Hello,
is there any way to configure different IP addresses and SMTP servers easily on the p3600?
To make a long story short...I use 2 wifi connections, one at work with a static IP, one at home with a DHCP. I use some software called "Easy net switch" on my notebook where you can configure several network configurations, and when you switch it automatically configures the wifi address, and the SMTP server of my outlook.
Is there anything similar for WM6?
Thanks
Luigi
I was looking for a solution as well, but found nothing. Then I configured my home AP to use a fixed IP address, the same as the one I use for work network.
I am sure there is something on this....HELP HELP HELP...especially for the SMTP server, I am sure that many people connect from different places...
You are not the only one looking for this, i connect to many WiFi and so having my home on the same network range as my main work isn't really viable. Anything that makes it easier to swap from DHCP to non-DHCP would be really appreciated.

ICS & VPN with WM6

My searches on the web haven't yielded much help or information so I thought I would come to the experts...
I have a Treo 750 that I just "upgraded" to WM6 2 days ago. I noticed that DUN has gone away and was replaced by ICS. After configuring my laptop to use that instead of DUN I connected and was surfing the web. My problem now is VPN. I travel frequently (luckily I'm in the office until Jan.) and regularly used my phone to connect to the corporate network via VPN. I also work with a lot of other companies and have VPN access to their systems as well. Basically now I can open my Cisco VPN client, connect to a VPN gateway, authenticate, get assigned all the appropriate IP information, but cannot communicate on the network. What gives? Is there a solution to this? If not, what the heck was MS thinking when they did this!? My phone is basically useless for one of the major reasons I bought it...
Any help is appreciated!
thanks!
Ok, further searches found that DUN can be added back into WM6 via a cab that was posted here at the XDA forums. I installed it and the DUN service is now visible again. I unpaired by phone and laptop, re-paired, and included DUN. Now when I try to connect, I get the DUN connection box after the bluetooth connection is initiated but when I click DIAL I get the DIALING... prompt, followed by Error 678: The remote computer did not respond.
Anybody get this working on a Treo 750? Thoughts, ideas suggestions?
What is the ip address you are getting via the cisco vpn client
It maybe that it is in the same subnet as the ip address assigned to the pc from the wm6 ics. The ICS gives the address 192.168.0.1. and if your Cisco is also giving a 192.168 address then you will have two routes for the 192 address range thus giving you the problem when accessing hosts.
If this is the problem Im pretty sure you can change the address allocated via the ICS using a registry editor. If not you may be able to get work to use a different range for you on the cisco vpn.
Our corporate network is 172.x.x.x so it's nowhere near the 192.168.0.x assigned by the phone. When I look at the route in the VPN client I see 192.0.0.0, 10.0.0.0, and 172.0.0.0 so I am assuming 192 is my laptop, 10 is the phone, and 172 is the corporate network.
I'm guessing NATing is the problem. I've been reading that if I use a different APN (isp.cingular instead of wap.cingular) there is no NATing. I've tried both, and I've tried turning off and on the "force AT&T" proxy setting to no avail.
Tried the DUN cab hack that is floating around for WM6 also. The service is active again and I can also add Modem Link back in and my laptop sees my Treo as a modem but when I dial I get an error stating the remote computer did not respond. I'm guessing along with going from WM5 to WM6 AT&T also updated the radio so the old communications protocols don't work anymore?
Hello Sir,
I have exactly the same problem... I have successfully connected via VPN, however unable to communicate with any devices on that network... Then what is the use of VPN on the phone? I've tried searching online for answers, but no luck... People are having the same problem but no one knows how to solve it... I'll try and trouble shoot this problem more as soon as my exams are done...
Hi
Working successfully for me. I am using Imate jasjam wm6. Pc using cisco client connecting via ics on phone. I have telstra 3g connection tested ok on both telstra.internet (Nated ip) and telstra.extranet (real ip).
You are correct it may be an nat issue. Can you check that your transparent tunnelling is on as follows: right click on your connection entry in cisco client and select modify then transport tab. Check that enable transport tunneling is enabled ipsec over udp(Nat/pat).
The other thing to check is that the cisco vpn server aslo has transport over Nat on as well.
Also are you sure your corporate ip range is 172 or is that the range given by the cisco vpn to clients.
Transport tunneling is on (always was). I'll have to check with our network admin and check on the VPN server setting...I guess as long as I have connectivity back to the office, I don't need it that badly for all the customers I need to connect to at various times.
Yep, positive on the corporate IP. Right now it is 172.28.1.87 and I'm in the office.
Thanks for the help so far. Got any other suggestions on how I can troubleshoot further?
One other thought...should I modify the registry on the phone to assign a different IP address to my laptop? Would that help?
Same Problem
MX. I am having the exact same issue but with Securemote VPN. I've looked through the registry and found the assigned address, but I'm wary of changing anything until I can find some more information.
Anyone out there ever change the DHCP configuration for their phone?
Somewhat related question?
Im attempting to route my connection on my mobile through a laptop acting as a wan bridge, then uplinking it into the router. The issue Im having is that XP and WM6 both use the same IP Block. Ive read and read and cant find much to tell me how to change the WM6 IP BLock to something like 192.168.2.1 rather than the default 192.168.0.1
Does anyone have any pointers? Ive looked through the registry. There MUST be a simple way to change a default.
To clarify my setup, I am using ICS Via USB into a UMPC laptop running XP. The UMPC is set to share that same connection back out over Ethernet. The ethernet runs into my WAN Uplink on the router and then back out via wifi/rj-45
This setup works as I have done it using Wifi with other networks, and I can chose the "Lan3" to share under the advanced settings on the UMPC. The reason I dont just share out via Wifi from the start is that Wifi on my Kaiser and Raphael both make the device to hot to charge, thusly killing the battery within a couple hrs of sharing. If I share via USB , it stays pretty cool and still charges.
Anyone have any pointers?
I have already tried tricking XP into using the Lan on another block but as soon as you try to share the USB lan, it reverts back to the 192.168.0.1
The only way I can imagine is a registry modification or a program change in ICS.
Thanks Much!
