# MASQ timeouts # [...]
Increasing the timeouts might not help since an inactive session will not cause any traffic. It might be wise to just configure ssh/sshd to send keep-alives. If the keep-alive thingy doesn't work out for you, you could still tunnel some arbitrary port through the connection and send a syn every once in a while into the tunnel. This should do it, too.
I hope that is of use :-)
