VPN Client Connection Problem

[walemc]

Hello

We use the untangler Free Version as a Router in our Network:

--> Cablemodem --> Untangler --> Internal Network

We configured the Portforwardings for our Webserver, Public-DNS and VPN and then created a setup for all Users. The VPN Connection worked as expected.

Then we configured a NAT-Policy on the internal interface to reach our Exchange Server. Afterwards we made a new VPN Client Setup File for a new User. Since then, we cannot use the VPN-connection. The error message is:

Tue Jan 10 09:49:23 2012 TLS Error: TLS key negotiation failed to occur within 60 seconds (check your network connectivity)
Tue Jan 10 09:49:23 2012 TLS Error: TLS handshake failed
Tue Jan 10 09:49:23 2012 SIGTERM[soft,tls-error] received, process exiting

The Untangler is still reachable over the Internet (https).
