We have 2 sites seperated by an ASA 5520. There are some servers on one side of the ASA which are hosting IRC (Internet relay chat) and SSH service. The clients for both services are on the other side of the firewall.
We are often seeing two issues:
(A) IRC will time out about every one hour.
(B) SSH sessions which are left idle will time out if they are inactive for about an hour.
Any idea what's happening here?
