ACS Invalid Administration Connection

[ebuckley]

I have an ACS box that is working properly and you can administer it remotely from any device except behind an 831 doing VPN to the host site. I have looked through the ACS and there are no IP or Port restricitions. Ocassionaly it will actually log in and I get to the home page, but it will then go back to the "Invalid Administration Connection". I am able to use other servers on the same network as the ACS from this device but just not the ACS. I have also changed the tcp-adjust mtu size but still cannot successfully log in. Anyone have any ideas.

The problem is in the Access policy set on the ACS Server.

Actually, I am not blocking ports or ip addresses in the access policy on the ACS. I am not sure what it is at this point.
