Cisco 3002 Hardware client connects a tunnel to 3030 concentrator in Network Extension mode.
Machines at the central site are able to reach resources behind the 3002 (via ping etc) once data is sent from behind the 3002.
If tunnel is left idle for a few hours, the Cisco 3030 reports the tunnel to be up and active, however at this point in time, no data can be sent from the (we are unable to ping devices behind the 3002) until data is sent from behind the 3002.
It seems that the 3002 looses its connection from the 3030 then imediately rebuilds a new connection. I have all timeouts set to "0" within the group settings for the 3002. Therefore the 3002 should keep all its connections up indefinitely. However this does not happen.
The logs on the 3030 indicate that the disconnection takes place with a reason "User required".
I would like to have the 3002 maintain its tunnel connection indefinitely.
Am I missing something here....
Is it not possible to do this, or is this a bug in Cisco's code
