Subject: 2.6.27.5 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.
