I have configured Cisco remote access VPN on most of my ASA firewalls without any issue until I have updated all of those ASA to version 8.2.4. It seems that when VPN clients connect to the ASA, they get successful connection but no traffic is happening. I am not sure where the problem lies now because all this remote access VPNs are working before the update. Has anyone encountered this issue before? The ASA versions are 5510s and 5520s. To have a brief idea on the setups please see below:
Scenario 1 (most of our clients)
VPN client (outside) --> INTERNET --> ASA 5510/5520 (successful connection) --> inside network (no network traffic traversing the remote access tunnel)
Scenario 2 (our office, where I remote connect to our clients, Client X represents specific client)
VPN client (inside) --> ASA 5510 --> INTERNET --> Client X ASA 5510/5520 (successful connection) --> Client X network (no network traffic traversing the remote access tunnel)
Thank you for the assistance.
