Problem using Cisco VPN to connect through a watchguard firewall

Asked by aspensystems in Watchguard Firewall

Tags: vpn, cisco, watchguard, firewall

I have a Watchguard 750e (recently installed).  I am attempting to use a Cisco VPN client to connect to a remote site.  Problem is that once connected, I am unable to access any network services on the remote site.  There are no error messages on the firewall to indicate a deny, and I have run a packet scanner on the internal machine and everything looks good here as well.  I do not have access to the remote concentrator or configuration.

I have enabled the following ports to allow through the firewall:  TCP 50, TCP 51, UDP 500, UDP 4500 and TCP 10000.  This connection is using NAT/PAT (as they all do).

Now, here is the interesting thing, I can connect to <some> Cisco VPN's this way, and have no problems, there are only a couple of them that show this behavior.  Any ideas?  Watchguard tech support really stinks.Start Free Trial
