Last week I decided to use TeamViewer VPN to administer software on a server behind a firewall using RemoteDesktop. It was easy to configure to start-up with the system and make VPN available on the other side but now it fails to connect at the step shown below:

TeamViewer failing to connect

The remote machine is running Windows Server 2008 R2.

Is there a native way to circumvent the external firewall using a server role or feature to make Windows Server do the VPN work?

Do people have better / more reliable experiences with other products such as Hamachi?

The requirements are as follows:

  1. Start at remote system start-up time
  2. Make VPN connections to the remote machine possible

By default TeamViewer uses only the outgoing port 80 - no firewall configuration is usually necessary, however you can open port 5938 which I've found to be necessary on some firewalls. I'm assuming the problem is when you try to connect to a server through TeamViewer and you're not even getting to the RDP part?

I cannot open ports in that firewall as it is administered by another department. Next week I will go and try to configure DirectAccess and other solutions on that machine. – Cetin Sert Mar 5 '11 at 3:42
