Hi, I have a Cisco 877 at a remote site which is in VPN mode. It connects to a Cisco concentrator at the HQ. If a users plugs his laptop into the back of the routers 4 port hub it bring the VPN tunnel up, if he takes it out the tunnel will go down.

Normally the 877 will be plugged into a switch but for 2 weeks it won't, so this keeps the tunnel up. Is this normal or can I some how keep the tunnel up?

I can access the external Internet IP of the router to make a config change in the CLI if needed.

I think you can't continously enable the tunnel between centerl site and remote site. Its depends upon the tunnel life time also. Whenever its required you can establish the VPN connection betwwen the devices.
