i have a site with an 806 as the remote access router via VPN to 3005.Using Easy VPN Remote
On the Concentrator, I set the Session to Idle Out after 2 hours of inactivity. it will idle out and immediately dial back in at night as it's supposed to.
but sometimes it does not dial back in.
it is sporadic. it may be fine for 2 weeks and then go bad 2 or 3 nights straight.
the 806 is fine once you reboot it.
BUT if you reboot the 3005, the 806 will not dial back in and negotiate a new tunnel. I have to reboot the 806 for the tunnel to be established.
The 806 is running 12.2(8) EarlyDeployment
