Subject2.6.27.5 tun/tap problem.

I have one machine that refuses to keep it's ssh tunnels up. None of the
other interfaces show any errors and I've checked for mtu problems etc.

About 40 seconds after the tunnel comes up it stops recieving
packets. If I start a ping on the machine it shows outgoing but not
incomming icmp. The machine on the far side is getting the packets and
replying but it's not making it over the tunnel. Both machines are
2.6.27.5.

Not even sure where to even begin debugging this.
