terminal server using VPN over umts

I am able to get a connection using Wifi with vpn and then terminal server connection to my work computer.
I am not able to do this over UMTS or GPRS, I cannot get a VPN connection.
Funny enough it seems that my UMTS connection is actually faster then when using WIFI

Your problem is interesting because I have exactly the opposite problem. I have VPN workng over UMTS, but when if I have wi-fi on & phone off, the VPN wants me to turn-on the phone to connect over UMTS!
Sorry I have no idea why this is happening.

I would like to know how both of you have done each of yours as I cant get either to work.
1. WIFI or UMTS connect...
2. Run VPN
3. Run terminal server, automatically disconnects my VPN. Servers are secure, no VPN to RDP.
Please advise your methodology as I cannot for the life of me get that VPN connection to stay on.
Dont get me wrong, UMTS, WIFI, and RDP internal of the networks works fine, just the VPN part stuffs me up

I had to create a work URL Exception under settings/connections/advanced
Once I did this there was no problem getting a VPN connection over WIFI

hmmm...
NLMCarl : may I respectuously ask wether when you turn on the wifi, it connects you to the Internet (which would explain why umts seems soo fast, since the path is the wifi then and not the umts anymore)
BBill : for your case, AFAIK, the umts is linked to the Phone provider plan (meaning the SIM card as well) so no phone means no umts at all. (very slow connection then )

Dont know if this will help but...
When I first tried a VPN over GPRS/UMTS on my Exec I, too, found that it didn't work. After a lot of testing I discovered that my provider (O2) was assigning my Exec a dynamic address on the 10.x.x.x network. Unfortuantely, my home network was also a 10.x.x.x network. Therefore, when the VPN was up and I tried to access my home network through the VPN, it didn't go through the VPN at all, but just tried to access a device on O2's local 10.x.x.x network. This, of course, didn't work.
For me, the fix was to change my ip addresses at home to avoid the conflict. I am now on 172.19.x.x at home and haven't had a problems since.
Hope this helps.

Has anyone got a VPN connection to work with a T Mobile MDA?

I am trying to establish a VPN connection but cannot get the connection to work.
I am using the built in MS VPN client of Win Mobile v5.0 (5.1.1700 build 14352.0.1.0)
I am having real problems getting a VPN connection set up with our network.
I have tried both PPTP and L2PT
When L2TP, I was authenticating with a preshared key
Firewall logs show PPTP negotiation successful, and issues a VPN IP address to the device
It can ping the firewall external interface, but times-out trying to reach an internal address
The VPN session is established, but the firewall logs don't register either deny or allow traffic for each internal ping request, rather the firewall packet error count increments for each failed attempt.
Any help is greatly appreciated.

I had problems with PPTP - gave up
I hate the way Windows mobile labels connections.
I connect to many customers with PC Anywhere, VNC, SSH etc and I have access via serveral different windows PPTP VPN.
Like you I setup the details in connections and try to dial.
Nothing seems to happen. The connect option does not change to disconnect. So I assume it is not connected.
I have a feeling these connection do not work over WIFI. and perhaps work over T-mobile 3g only, to maximise data revenues.
Seems very buggy to me. I would really like someone to post a working example/Instructions. Can I get a refund on my MDA PRo?
MS please note it is not a connection to my work or an internet connection it is to a customer for remote support, likewise I often connect remotely to my home via PPTP from my office.

confirmed VPN works over t-mobile 3g not Wifi
SEems the VPN links only work over 3g not Wi FI.

I'm using a PPTP connection over either 3G of WIFI depending on te active connection.
- When WIFI is active the PPTP connection connects using WIFI (I can switch off the phone, so it must be using that one)
- When no WIFI connection is active it automatically connects to 3G first, and than starts the PPTP session
In network management I'v set:
Internet:
Internet (the one containing the 3G connection)
select 'this network connects to the Internet' on the proxy tab.
private network:
My Work (the one that contains the vpn connection)
do NOT select 'this network connects to the Internet' on the proxy tab.
So as you can see, nothing special (I'm using a Qtek 9000 with standard Wm5 ROM)

WiFi and GPRS

For some reason I can connect to the internet very easily through GPRS (even when roaming), but at home with my own wirelss LAN, I can connect with no problem, but each time I try to access anything on the internet, I get a pop-up stating "Could not locate remote server". I don't have a router, I am using a desktop as the gateway, I am currently accessing the net with my laptop through the same means. All configurations for the LAN appear to be correct, but I must be missing something on the JAMin. In the WiFi settings, I see the LAN, almost full signal - Ad hoc Mode - status is connected - I'm assigned an IP ... seems like everything is in order.
Will one of you wizards point out what I've missed? I know it's probably simple, usually is.

If I'm having trouble connecting a device to a network that has previously been working ok, the first that I do is turn off all network security i.e WEP, MAC address filtering etc. Then reboot the wireless access point/router and your device. If you still can't connect, you can start to blame your device.

Don't think it's a network prob...
Thanks Matterhorn, but my laptop is still connected fine, no problems there... I get the feeling that the PPC's only recognising the GPRS as a valid network for internet access... it works okay when I login to a commercial WiFi network (when I'm in the States) but for some reason on my own network here at home, it logs in, just can't find a server for some reason. The first thing I thought of was the firewall, turned it off and still no luck.
Any other ideas? I thought maybe there was a setting for default AP or connection, but can't find it, nor can I find an appropriate reference in the manual. Ugh!

Resolved!
It would seem my JAMin was trying to access the internet not through the gateway, but through my laptop. As I don't have the laptop setup to share an internet connection, it would allow my JAMin to connect, but that was all. I went in the room where my desktop is, registered on the network there and bingo!
Too simple, should have tried that right away but it didn't occur to me at the time. Thanks for the help anyway Matterhorn!

Bluefire VPN over 3G

HI there,
Has anyone experienced an issue whereby bluefire or similar contivity VPN client connects seamlessly over WIFI and 3G however will only allow RDP or VNC over WIFI.
I am currently running bluefire and am able to authenticate through 3G but thats it, I have no other functionality.
Any help would be great!
Thx

I've seen it where specific ports are blocked on the 3G providers network, but given that you're establishing a vpn tunnel, that should be irrelevent, as all the traffic should be tunneled via the VPN. I wonder if the Device isn't picking up the new route to send the traffic via the VPN, and is instead sending it via the 3g connection to a non-existant device.
Does your VPN-endpoint give you any logs to show if its actually receiving the traffic from the device? Are you able to ping anything within the remote network (assuming ping is allowed) from the device?
One thing I have noticed is that if you have a 3G connection open, then establish a wifi connection, the routing table doesn't seem to update to use the wifi connection and you actually have to kill the 3G session. I wonder if something like that is happening here - the 3g session establishes a default route, the VPN session then comes up but the device doesn't realise to send traffic via the VPN session. Or are you getting any traffic through the 3G/VPN connection?

I have the option to turn on verbose logging. I ll give that a go and see if it highlights anything really obvious.

VPN Pptp over wifi in HTC Leo

Hi!
I have been trying to connect to my to vpn pptp server (witopia.net) for 2 days. I tried every combination that i could think, but there must be something i am doing wrong. I think the mobile is trying to connect to the vpn server through gsm because everytime i try to connect the gsm signal bars disappear for a few moments. How can i make sure that the vpn connection goes through wifi?
I have managed to actually connect to the vpn server, but i cannot access websites like facebook and youtube from the Leo (I live in China and they are blocked). I am able to access blocked services through my iphone and laptop through the same vpn connection.
Any suggestions?
Thanks

PPTP on WM6 is a major problem. Especially if the server (and most do) required MPPE. Its one of the few niggles I have about WM. If you own the server your best setting up the conection using L2TP/IPSEC.
Or if you dont own the VPN server, and have a server laying around the house (as I do) you could set up your server to use the PPTP VPN then set there server as a Proxy, and connect WM6 to the server via proxy...so basically WM6>Proxy>VPN>interwebs

Hi Jagnet, Thank you for your reply.
Unfortunately i am not able to use Ipsec/L2TP in China, only PPTP works fine with blocked sites.
After trying many combinations, there is a step that i havent been able to figure it out.
Once i am in Start > Settings > Connections (tab) > Connections (icon) > Advanced (tab) > Select Networks, How do i select the WIFI connection in "Programs that automatically connect to the internet should connect using" opcion? . On the modem tab i only can choose "celullar line", "Celullar line (GPRS)" or "Hayes Compatible on COM1:", there is nothing about WIFI there, so when i try to connect at the vpn server specified in "Programs that automatically connect to a private network should connect using", the phone seems to be trying to connect via GPRS.
¿Any ideas?
Thanks

having similar issues with HD2. CMCC as well, in China.
I am getting a proxy IP address if I check on ipchicken.com, etc
but I am not able to open FB.
I am not using the PPTP option, but using their SSL service with
openVPN. but STILL not working..
right now on support chats with witopia.

VPN PPTP is simply broken in WM. It will work, but only with no encryption at all, which beats the purpose.

First of all sorry for bumping this old thread. But I have been looking and it seems kinda close to what I`m doing, oh a little new to vpn.
I have managed to sucessfully connect the HD2 via VPN in connections only when on the lan (outwith I need to contact O2 to get it enabled apparently). I setup a dialup connection in Win 7; HD2 says I`m connected to the VPN.
However heres the thing. Am I right in thinking that folders by default have to be shared. Therefore when using resco I can see network folders anyway, when connected to wifi.
So how would I prove that I can see folders shared to the VPN and not on the LAN as I cant seem to prove whether I`m seeing the folder via LAN and not on the VPN?
Sorry if its confusing but perhaps you get my drift? Or am I missing the point entirely....
