OK - I think I'm getting closer.

On a hunch, I tried turning off my "eth1" - leaving eth0 and eth2.
It works perfect.

So - I believe I'm not facing a firehol problem (yeah!) - but a routing 
problem.  I guess there are some additional steps I need to take to set 
up a router with two default interfaces.

So while it may be off-topic - can someone either advise me on this or 
point me to a good reference?
