Hello,

In addition to the above, I have exactly the same issue.

What I can do - no issues seen so far:
Connected via ActiveSync, I can use RDP and connect without any issues to our W2k3 server park.
When I am on the road, I use a 3G cellular connection. Connecting to the internet works without any problems. Over this 3G internet connection, I'm setting up a VPN tunnel to the company. No error messages here: when I click on the connection icon, it tells me I'm connected to VPN.

When I check my IP address via the free tools from Cambridge, VxUtil etc, I can see there's a public internet address 81.x.x.x on my cellular. I would expect another adapter in that same list, displaying me a private IP address from the VPN, but it is not there. Don't know whether this is a shortcoming of VxUtil or not. Let's say it is not, I tried to ping the servers in our private range, thinking I have setup a working VPN connection, but I get time outs...

Now that made me think that our current setup does not allow RDP over VPN, and maybe we need to open some ports on our ISA firewall...
I made an analog connection to the internet (using the PSTN line, plugged into our fax machine), over that connection I set up a VPN tunnel to the company, and then I managed to connect to the servers via RDP without any issues, so the setup seems to be okay...

So then I need to come back to the VPN connection on the WM6 PDA: I should be able to see a 192.168.8.x address, once I have established my connection. Should I be able to see this using the IPConfig tool from Cambridge, or... ?

Anyone else next to the ppl in this thread, having similar issues setting up RDP over a VPN tunnel over a cellular link (3G).

Thanks again,
Mario
