I have a test environment with ASA5505 (8.2(2)4) and Cisco876W (12.4(24)T)) doing ezVPN with NEM from Router to ASA.
Everything ist fine, tunnel is coming up and I can get through it from both sides.
After an idle time of 60min (=3600s) the tunnel gets disconnected. ASA tells "Reason: User Requested".
But at the router the VPN-Led ist still on and it still has an active SA.
Even if I have traffic from the inside of the router towards the tunnel, it doesn't reestablish.
I have already checked all timeout-values but none ist at 3600s.
ISAKMP Keepalives and ctcp enabled.
Config Snippets are attached.
Thank you for any suggestions
