For the last few days I have had a timeout when trying to connect to all of the servers which I administer using my XDA. I can connect through my other ISPs. I rang O2 to ask them if they are blocking the RDP port and got passed from customer services to network support and then to data support... no one understood what I was talking about. They said that so long as you can connect by GPRS then that's where their obligation ends they don't support any particular protocol. Has anyone else experienced a similar problem?

Hope some one can help with this - I am sure I've seen posts on the subject but can't seem to find them
Set up a PPTP VPN connection to use the wifi connection, all advanced setting set to enable this (same settings work on and ipaq with 2003se)
what happens is the xda connects to the vpn server receives an ip address and then drops
the logging on the server shows no errors
I have spoken to O2 who recognised this as a known issue but had no timescale for a fix/workaround
I have tried different radio versions and different OEM's roms to no avail
I suspect either the hardware or the WiFi driver but I'm no expert on pocket pc stuff
Would be grateful for a share of thoughts or even fixes on this subject
as this was the primary reason I bought six of them
Have tried latest o2 rom - issued by o2 today
doesn't fix the wifi/vpn problem and doesn't upgrade the radio either
another half hearted effort by o2 :twisted:
I realise that this is no consolation but I have also had this problem trying to connect the WM3 VPN client. You seemed to have got a bit further by getting an IP addr from your VPN server. Another point to note is that if you try to connect to your VPN server via GSM (instead of WiFi),
the connection session goes a little further (if you check thru the server logs) but again, in my case, it ends up with a "VPN server problem, check your username and password...".
Our VPN server happens to be a PIX firewall, can I ask which VPN server are you using ? :x
VPN
We are using a simple Windows server VPN PPTP for the purposes of testing - it works fine over GPRS just not wifi
I have had an email from O2 confirming that they are aware of the problem - but the last rom update is the last one they are going to issue
and they have no plans to fix the problem
I will be taking this further with O2 and will let you know the result
in this forum - but I don't hold out much hope
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?
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.
I have a Blackberry on O2 that accesses our corporate BES but I wondered if I could get it on my Tytn if I moved the SIM and installed the desktop and PPC software. I did and eveything looked good, was getting mail but found the Services 'Blackberry [CMIME] is marked as disallowed and although I can receive email, I can't send. Anyone know if the are connected?
Also the Blackberry service does not start when I reset the Tytn, saying I have no connection so I have to manually start a GPRS connection and continually keep trying to re-connect, eventually it does but it would be great if the service could start automatically on reset with active connection. Does anyone know if there's specific settings I should be using for my setup? I'm using the desktop and ppc blackberry connect software found on the hermes FTP area.
Thanks in advance.!
POPSSIBLE i think, search for the subject in the TyTN upgrades forum section i think i saw a thread a few weeks ago on this...your SIM must have blackberry access so you should be ok?!
I'm almost there, I had to recreate my BES account so my service books come down fine and I can send email. The only problem I have now is that if I restart the tytn, the Blackberry service won't connect, I get either a message thats says 'NOT CONNECTED' or 'STOPPED'. Nothing else has changed and I have an active O2 GPRS connection on a Blackberry enabled SIM. Anyone else had this problem getting the Blackberry service to connect?
I'm kinda trying to break the rules here but would still appreciate any advise that can be provided.
I have installed the Blackberry software as linked from this site and got my network admins to set me up on our corporate BES. I have used the desktop software to setup the software and build the key.
I have a GPRS data package with my phone but not a BlackBerry package.
Should I have able to connect to the blackberry service or would I have to open a BB service with my telco.
Any advise would be a appreciated.
Short reply to my own post. You definately need to subscribe to a BB service to get Blackberry Connect working. I'm not sure of the technical aspects but BB uses a different approach than just straight UMTS or GPRS data. Each time my PDA tried to connect to the service the GPRS connection would flash briefly and then drop. I have now tested this on a SIM with an enabled BB service and it works perfect.
