We have a simple remote access vpn configured in cisco asa firewall ASA 5580-20 with code 8.2.5.
Randomly or once in a while all the remote users are unable to ping/telnet/access the resources through the asa, though they are able to establish vpn client session.
The problem would exist for 1-2 hrs and automatically it will get resolved. There wont be any config change in firewall before or after the problem. Can someone give hint on what could be the problem and how to troubleshoot further. It would be better if you can give all the commands in a single update.
