I am running a Cisco VPN on my PIX 515e firewall with IOS 6.3 <5> software on it. Over the weekend I cut over to a new T-1 circuit and the IP address on my outside interface changed. I am now not able to connect to my VPN and I get the message:
Reason 412: The remote peer is no longer responding
There is nothing in the access-list that is blocking VPN and is was working fine before I changed the IP address. Does anyone have any ideas on what else may need to be changed?
