RE: VPN Tunnel Stalling

["Paul Melson" <psmelson () comcast net>]

What version of the VPN 3000 software is running on your concentrator, and
what type and rev. is the remote endpoint?  

I saw a similar issue in the wild a couple years back with a 3015 running
one of the 3.x releases (afraid I can't be more specific - it was too long
ago) and a PIX running 6.2 where after about 24 hours (perhaps not
coincidentally the key exchange lifetime), the tunnel would go quiet.
Administratively disconnecting the tunnel at either end and then passing
matching traffic would bring the tunnel back up, as would restarting either
device.  The resolution was to upgrade the 3015's software.

Subject: [fw-wiz] VPN Tunnel Stalling

FW gurus,

I'm having a particular problem with a site-to-site tunnel on a Cisco VPN
Concentrator 3005 (Running 3.6.5). There are a number of other tunnels that
work without issue, but one in particular stalls at least once a day and
traffic stops (although the tunnel remains up). Forcing the session to log
out and letting it come back up results in traffic being able to pass again.

Any thoughts on a possible cause?

Cheers,

/j
