I recently upgraded my remote vpn access from a VPN concentrator 3030 to an ASA 5540 (8.2.2). For the most part the upgrade completed without trouble. I have had a couple of instantances where remote users are able to connect but not pass traffic. The users are prompted for a username and password (xauth). Authentication passes, they are then prompted to accept (ok) the VPN message banner. No data passes at this point. From the ASA I can see data decrypting and encrypting. From the remote client, I can see data encrypting but no data encrypts.
