VPN connection through terminal server

Posted on 2008-10-29
Last Modified: 2010-04-18
I have a terminal server in my network which many remote people use. Some people (no matter how many time I told them no) connect to VPN client on this terminal server. Sometimes I am able to access server locally while they connect to VPN sometime I don't. But in any case terminal server becomes unaccessible from public IP when someone connects to VPN client.

Whats the best way to resolve this situation?

So they log into the server remotely and THEN, from their remote desktop, open a VPN connection FROM the server to somewhere else?

Yes dfxdeimos. Exactly. I need a way to stop them from doing that. This can be anything, MS VPN or webVPN.

Do you use VPNs at all inside the office?

It may be feasable to use the Windows Firewall on the machine in question to block OUTGOING connections on the ports required to establish the VPN connection.

Here is a list of common VPN ports:

I will try blocking all ports listed and see if any user complains about anything.

I am not too sure if it worked or not but I didnt have any issue for last few days.
The solution might have worked or people might not have tried to connect VPN.

Anyway, I will accept your suggestion as solution and will open new post if problem persists.

Thanks a lot for your help.
