We have configured remote access VPN in our ASA5540. (ASA Ver. 7.2(2). We have 3 VPN groups setups. Sometime any users belongs to any of these groups diconnect after 05-06 seconds once they connected. Once I re-start the ASA all users are able stay connected but again it happens after 1-2 days.
Please advise me what causes VPN users to disconnect immediately when they loged-in.
