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.

Odd question about connectivity

I have been talking to at&t customer support (without success BTW) about a strange problem. Here it is:
I recently received a replacement 8525. My previous 8525 had the original ROM and the latest has the new ROM upgrade. On GPRS, the old phone would connect to isp.cingular access point name but the new phone won't. The new phone will only connect to wap.cingular access point name. (Both phones used/use the My ISP (without the proxy) network.)
With my previous phone, I was able to download radio show podcasts by going to the website of the radio show and then click on the download link. A "Save As" dialog would display and I would save the mp3. On the new phone the PIE displays that it can't display the page.
Here is the strange part. When I connected to my Wi-Fi at home (NOT through a PC but directly to the wireless router from the phone) I could download the mp3 just like the previous phone. I went to the web site, clicked the link, and received the "Save As" dialog.
This looks to me that there is nothing wrong with the phone since the mp3 could be downloaded through the Wi-Fi connection, but there is a problem getting the download through the GPRS connection.
Am I wrong in this? Any ideas will be welcome, I'm getting tired of talking to at&t.
Thanks.

I had the same problem before.
When ever your plan or phone changes (or anything with your account) your isp connectivity is turned off.
What you must do is call at&t and tell them to turn your isp.cingular back on.
If they give you some lip (I haven't had any lip from them)Just tell them that your VPN will only work using isp.cingular.
I've had to do this 3 times.
Also don't forget to remove the "EnableAutoDetect" from the registry...that will also stop PIE from working under isp.
HTH

I'm assuming you have the PDA connect plan if you're trying to use isp.cingular, right? Also, if you're using wap.cingular and you can't access the web as usual, you probably have a proxy set up. Check that out and report back.

How do I check to see if I have a proxy set up?
I have my "My ISP" network configured to connect to wap.cingular which doesn't have the proxy selection. That is the network I am currently using. I have also found a program on my phone call Proxy Manager. It consists of two programs: Disable Proxy and Restore Proxy. Do I need to run the Disable Proxy program?

AT&T now acknowledges that the 8525 cannot connect to ISP out of the box. The fix came out around wednesday 7/25. Their fix is to run the Disable Proxy in the Proxy Manager folder in Programs. This didn't work for me.
I performed a hard reset and tried AT&T's fix again. It still wouldn't connect. So I tried to delete "EnableAutoDetect" from the registry. After attempting to run PIE (and failing) I looked back in the registry and it was back. I noticed the value of "EnableAutoDetect" was "0". So for fun I set it to "1". I was able to connect to the internet.
I then modified the "My ISP" settings to compress the headers and the "EnableAutoDetect" was reset to "0". I reset it back to "1" and it has run ever since.
So if you have an AT&T 8525 and you have PDA Connect Unlimited and cannot connect with the "My ISP" settings do this:
1. Go to Programs/Proxy Manager and run Disable Proxy
2. Set "EnableAutoDetect" to "1"
If you make changes to the ISP like the setting to compress the headers, you may need to reset "EnableAutoDetect" back to "1" again.

Very good info. This problem has annoyed me quite a bit because the wap versions of web pages really tend to suck. I'll give this fix a try later tonight.

These fixes didn't work for me.

The primary purpose of 'Disable Proxy' and 'Restore Proxy' is to flip the EnableAutoDetect value back and forth. (disable - 1, restore - 0).
AT&T is also in the habit of sending phones out with MEdiaNet and 'My ISP' both configured for wap.cingular. May need to change 'My ISP' to isp.cingular if you have a PDAConnect plan.

I have the PDA connect plan, and my 8525 came configured originally with isp.cingular as the default. It wouldn't connect. I changed it to MEdia.net and now it connects, but to wap.cingular.
I'm actually kind of guessing that the proxy settings are on the wrong track on this for me, because I get a message that the modem has disconnected. A proxy setting shouldn't disconnect the modem, it would just make pages unable to display. There's something on Cingular's side that doesn't like my phone, either my password is incorrect or they need to provision it properly.

The current disposition of the proxy (i.e., enabled/disabled) won't prevent your phone from making a data connection, nor is it required for wap.cingular or isp.cingular. Enabling it allows you to access AT&T's "internal" services over GPRS (and only GPRS, incidentally).
The ability to use isp.cingular is usually driven by the plan to which you're subscribed. I'm not able to use isp.cingular, for example, because I have a MEdiaNet plan. I think AT&T may have a long-term plan to do away with isp.cingular, but I'm not sure.

I talked to ATT today and they provisioned it so that I could connect to isp.cingular. This worked during the time that I was on the phone with them and then resumed not working after we ended the call.

heeellllllppppppppp

GPRS network problems - connects fine but not data.

Hi,
I use my trin to check mails and surf the web every day - that is, I used to do that. A couple of weeks ago I went to UK (I live in denmark). Here I turned off data connections in the commgr until I came back home. I did use it with wifi connections over there.
After I got back home, it does not work anymore. I can connect the 3G data connection just fine, but it seems like it tries to send data via a proxy of some sort or DNS isn't working.
I did some tests with vxUtil (small network util) and if I ticked off "resolve addresses", it actually did traceroutes, pings and web catch etc. just fine.
I looked at the ip address of the DNS servers and they seem to be the correct ones (the ones I am automatically given by my network provider when connection to their gprs AP).
Does any of you know any registry settings or whatever that can have an impact on how I connect to the net and resolve addresses?
BTW: I also started the zsIRC client and it connects just fine. I suspect that it caches the IP address of the server and uses an identd to identify with.
All help will be appreciated (hard reset not an option)

T Mobile UK Vario IV Data Connection

Hi Guys,
I have been searching the forum and the net for most of the day trying to resolve this one.
I have a T Mobile Vario IV and have reflashed it with Proven ROM 2.4 and the up-to-date radio. I use a hosted exchange server (sherweb) for my email, contacts and calendar.
When using wi-fi, the internet and activesync works perfectly and I synchronised my contacts and email folders using this after the reflash.
When using the T-Mobile data connection, the internet works fine but activesync is not able to talk to the exchange server and times out with a message suggesting checking connection settings. I have checked, checked and checked again all the gprs and data settings and they are all as advertised. I have even resorted to asking T-Mobile for a configuration message for data settings which didnt work either.
It seems that Activesync is not able to do its job via the T-Mobile data connection.
Does anybody have any ideas at all?
Thanks in advance
Chris
PS - The activesync worked fine over the T-Mobile data connection before the reflash.

UPDATE!
Sorted it out in the end, make sure that you UNCHECK the "This network uses a proxy server to connect to the internet" option under START-SETTINGS-CONNECTIONS-CONNECTIONS-TMOBILE-INTERNET-PROXY SETTINGS

Cannot Connect ActiveSync via GPRS using MyWork Network

Very Strange Problem with ActiveSync over GPRS.
I upgraded Imate JasJam WM6.0 to HTC HD2 Telstra WM6.5.
Device uses activesync over Telstra NextG to My Work Network with Exchange Server 2003. Setup the new HTC with the same work network authentication credentials, used the same Activesync credentials for Exchange Mail Server. I now have the default Telstra Internet connection plus MyWork Network connection. The new WM6.5 connections area is a little different but not too difficult. I started it up and worked first time. Fantastic.
I purchased another HTC HD2 and did the same for a work colleague. Once again worked first shot. Fantastic. Couldn't be happier with the trial.
Purchased 10 more for the rest of the team to upgrade their Jasjams. Setup the next one and no worries with the connection but it would not start active sync. Then setup the next one, with exactly the same problem - activesync spins for about 30secs then pops the 'Cannot Connect' error. Then I setup the next HTC and it worked perfectly. The Jasjam upgrade program is now stopped pending resolution!
So we have 3 that will sync to exchange mail and 2 that won't. I still have a drawer full of brand new HD2's so I try other devices, same problem. I move the SIM back into the JasJam, no problems so its not the SIM or the user credentials. So I try using my own credentials into a HD2 that won't sync and get the same problem, HOWEVER, without touching my own working HD2 whule testing the faulty one, my own device will now not sync either.!
The Work Connection dials telstra.corp and my credentials establish the connection OK which does work and can run other remote apps. The cannot connect error has a blank where you would expect to see the number dialed so it means that activesync no longer knows how to connect. If I change the internet connection from Telstra Internet to MyWork Connection then activesync works OK. Then change it back to Telstra Internet and Activesync still works OK, so that seemed to solve the problem, but now the device cannot connect to the Internet. This is all very strange.
Have tried internet/dedicated setting but this seems to ignore me anyway.
Have tried diabling '...Faster Data Sync..'
Device syncs via a USB/PC connection without a trouble.
Anyone got any ideas. Thanks
Workaround found but its still strange behaviour.
On the HD2 the Telstra connections can't be edited so I created a new one and supplied the access point, IP address and proxy from the old JasJam. The HD2 now has my work connection and my own version of the Telstra connection. This seemed to do the trick. I now have Internet from Telstra and activesync via GPRS to my work Exchange Server.
However what caused Activesync to not know how to connect in the first place?
I would appreciate any ideas you might have. Thanks

I have been having exactly the same issue as posted above and have been tearing my hair out for the last couple of days trying to fix it.
I am syncing using ActiveSync on my HD2 ( WM6.5 ) to Google calendar using google sync and was getting the same unable to connect error or ActiveSync just sitting there saying Waiting for Network.
Syncing worked fine if I connectd to my Wireless network but OTA just wouldn't work.
After much googling I came upon this thread so tried setting up a new connection to Telstra Internet but this didn't fix it.
But then I happened upon the solution, so thought I'd spend the time posting it here in case it can help somebody else with the issue.
Open Tools/ActiveSync on the HD2, then Menu/Options.
Highlight "Microsoft Exchange" and press Settings.
Assuming your settings are already entered and correct, press Next until you see the list of what to Sync (Contacts, Calendar etc).
Now press MENU and select Advanced.
Under Connection, change this to Internet (click OK if you get a warming about not using a dedicated connection) , and press Save then Finish, and finally press OK.
As soon as I did this syncing worked via the Telstra Internet connection and has worked perfectly for the whole of today.
So I hope this helps somebody else out there who like me may have been googling for ages trying to find a solution to this issue.

No Activesync Through Telco Connection
I was also having activesync issues. The connection worked fine via WiFi through any access point (home, work, friend's house) but would not sync through Telstra Internet.
I was trying the "internet" option rpalmer68 mentioned when I stumbled upon the "Sync data when roaming" setting in >SETTINGS >DATA SERVICES >ACTIVESYNC.
After turning this on magic began to happen. All working perfectly.
I realised that I still had the "internet" connection set as above and went back to change it when I noticed it had changed to "dedicated".
I am using stock standard Telstra issued HD2 and haven't needed to modified any network connections.
This may be a simpler solution to try with the same outcome.

I had the same problem with my HD2. Changing the "Sync data when roaming" made no difference.
But rpalmer68's solution worked perfectly.
I noticed that I had to set the connection to Internet (this made it work). And then, when I checked the settings later, it had changed itself to Dedicated.
Setting the connection to Dedicated myself did not solve the problem (it changes itself back to blank).
