[K12OSN] OT - Linux router - I'm stuck <-long

[Christopher K. Johnson]

Tim,
What interface is used makes no difference.  Whether the interface used 
has the correct subnet, and whether the correct routes are configured is 
what matters.  You already verified that ip forwarding is on.

I found it too difficult to decipher what the connectivity and routing 
configuration were from the original information.

Take another shot at describing your situation:
Please state the system names and provide the output of 'route -n' for 
each of the systems involved.
It would also help if you document connectivity, for example "system1 
eth0 connects to system2 eth1", etc.
The output of 'iptables -vnL -t filter' and 'iptable -vnL -t nat' for 
each system would be helpful to make sure there is no filtering or 
natting causing the problem.
Then restate what pinging fails using the system names and interfaces 
you have just documented.
Hopefully we can help you with the above information.

Chris
