WM6 won't connect to PPTP VPN over gprs or wifi

[nkitson]

Hi,

I am trying unsuccessfully to connect to a PPTP VPN using the VPN client built into my new HTC TyTN II.

Wifi - I can connect using a WinXP SP2 laptop using wifi through my home linksys wireless router (which has PPTP passthrough enabled) using the standard Win XP vpn client. When I try with my TyTN II, I can browse ok but if I set up a VPN connection I get "VPN server problems. Verify your username and password, etc"

GPRS - If I try to connect over GPRS, I connect to Orange GPRS but when it tries to connect to the IP address of my VPN server, I get the same VPN server problem error message. (As a side issue, I asked Orange to enable my account for vpn which they did, sent a SIM update and told me to change my apn to 'internetvpn' instead of 'orangeinternet')

As I can connect through my wifi connected laptop, it seems to point to my WM6 vpn client but my forum searches suggest that the WM6 client works ok. Oh, and yes, I have checked that I am using the correct vpn username and password!

Any thoughts greatly appreciated - the ability to maintain some linux servers was my main reason for getting this phone!

Bump!!! Same problem here. I have all the proper ports open on my router and still no luck.

I've been trying to resolve this with the people that manage my vpn server which is my case is a Watchguard firewall - apparantly Watchguard isn't compatable with PPTP on WM6 and they have suggested using IPSec and have provided me with a client (not that I've got that working yet either!)

I suggest you contact the vendor of your vpn server and ask them whether they are compatable and how a WM6 client should be configured. Post anything you find out here for the benefit of others.

Friends...
I have the same problem... the VPN server is Windows Server 2003... My PDA has WM6 (with in-build VPN client)... then VPN PPTP would work OK... but What is the wrong??

I also could not connect on vpn over GPRS and got error message, but after I tested all installed programs I have found out that my SPB GPRS Monitor was the reason for the errors. So I killed it.
Now VPN over GPRS connects and looking into register I see that I am really connected i.e. I got DNS server IP, I got name of the local network and dynamic IP for my HTC, but nothing works. As I have found out from server guys they see me but my dynamic IP is not logged in server DNS, so no program sees me and I can not work.
Can somebody help?

I have a similar problem but the difference is that i don't even receive an error message. When i click connect NOTHING happens!!:confused: The wifi i am using is an open network but I must connect to vpn to connect to the internet.
Please help as i really need to get this working...:(:(:(

I have been trying to iron this out with IT at my office as well. I have been trying to get WM6.1 VPN working for nearly a year.

I have a TyTnII and my IT office just bought some kind of WM6.1 Motorola/Sprint Smartphone as well which they actually asked me about setting up for them.

The problem what I am experiencing is that I CAN connect to the VPN server (I use one of the TaskMan progs that has ipconfig built it, and I am getting an appropriate IP from the VPN server). BUT I can't browse ANY intranet sites via PIE or Opera Mobile 9.5. Whenever I try to browse to an intranet site I just get nothing, browser does nothing for ~10min then gives timeout error.

I have heard that this has to do with an inbuilt error in the PPTP module of the VPN client that incorrectly makes VPN server requests using the IP address assigned by the GPRS/EDGE/3G/etc. connection rather than the IP address assigned by the VPN connection, obviously will cause problems!

Anyway, we are investigating 3rd part VPN clients...

I also made many tries to get vpn working over BT PAN profile.
The only configuration which worked for my was IPSEC with the Safenet SoftRemote-LT Client on PC.
With the windows native pptp based vpn does not work .
I got the error code 721 what means that the GRE protocol (frame type 47 on port 1721) does not pass through. This seems to be the the real problem of the packet filtering components of the WM device. The problem is not related to bluetooth or PAN Driver, because it behaves in the same way if you try to do it over USB port. No way.:(

Getting what you want to work over VPN requires work URL Exceptions so that the traffice is properly routed.
