Pedro,

Can you post "netstat -rn" output from the machines you are tesing from
in all of the different "lans"?  Also, I've never seen traceroute output
quite like you show.  Could you do traceroutes from your "firewall"
machine to hosts in the other "lans" and from hosts in the other "lans"
to hosts in the other "lans" that would have to cross the "firewall"
machine and post the output of that information?  Also, you *may* have
to use -i with the traceroute (but man says it should *just work*).
