Topic: VPN tunnel idel time detection

[Andre Courchesne]

Hi,

Problem: Remote client leave their VPN tunnel up all night without actually using it...

Is there a way to detect idle time on an VPN (PPTP) tunnel and "safelly" killing the connection if there was no traffic for let's say 30 minutes?

One way I would think is to monitor RX and TX packets on tunnels and if nothing changes for 30 minutes, doing an ifdown on the tunnel. Is that acceptable?

Thanks,
