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.

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?
I connect to a WiFi network where each component has a static IP, the problem being that my Hermes will take the earliest free IP address that it can find causing the PC which has that IP address to start spouting errors?
How can I remedy this?
If you have access to the router or buzz the (lousy ) administrator, configure the DHCP to a range that noone has a static IP in (for example x.x.x.250 and up)
After playing around with the router I think that I might have struck gold. Thanks for the speedy reply. I'll post an update in a day or two.
You can set fixed IP addresses on the device as follows:
Start>Settings>connections>Network cards>network adapters (tab)
Here you can then tap each type of connection on the list and choose either server assigned address or enter a specific address.

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.
Hi.
I need about a software, that allow to set multiple WIFI profiles, because in my home i need to SET MANUALY HD2 WIFI with net adress (192.168.1.1 etc.), but when i go out, i need to catch FREE WIFI SPOT so i need to set rapidly WIFI Configuration with AUTO IP (and when i'm at home, return to Manual Adress).
I had tried WIFI Profiles, but i can't understand how i can put AUTO IP ADRESS there.
Please help me !
Compliments for great site !
There is a program called Wifi Monster, have not explored it a lot, but sounds like it might do what you want ...
Just search for it ....
Hope it helps ...
i'm curious about why you have to use a static IP for your HD2 at home. you can set your home router for DHCP (just like the rest of the WIFI hot spots you like to connect to). if assigning a specific IP to your HD2 or to other machines on your network is important, why not use "static DHCP"? static DHCP is configured in your router and will ensure that each device gets the same IP address every time.
i have configured my home router so that 10 IP addresses are available for machines. the first 5 IP addresses are assigned to specific machines using static DHCP. the rest of the slots are available for guests and friends who occasionally bring their laptops/smartphones to my place and need to get on my network. the router works intelligently by reserving the static DHCP IP addresses only for my specified machines and uses the rest dynamically for unspecified machines.
on top of all this, i have MAC address filtering to keep a tight ship.

Maybe he needs a static IP for Work, some places still use statics ....
Thanks ASCIIker & WATCHER64
I'll try all your suggestions, however the first work fine, i'll fix MANUAL ADRESS on DHCP and put AUTO on HD2.
All work fine now, but i'll try also WIFI Monster when i need only MANUAL ADRESS on my ROUTER.
Thanks to ALL !
With IPv6 coming on strong, isn't it time that all cell phones had static IP addresses? Just think of the possibilities if each phone had a static IP address: Notifications could be easily sent from any desktop app to your cell phone. You could even run a web server that shows what your camera is seeing.
There are a few apps out there that try to do the DynDNS thing, but they really only work when you are connected to a wifi network.
I have heard that Sprint will sell you a static IP address for $3 per month. I don't know if it is true (I have tmo), but I do hope it is and that it is just a (hopefully short) matter of time.
