Rick,
   This did not seem to be the case, or I am still misunderstanding you. 

Gentoo -> Gentoo - worked
Gentoo - FC2 - failed
FC2 -> Gentoo - worked
FC2 -> FC2 - failed

Gentoo -> FC2 (with iptables disabled at target) - worked
FC2 -> FC2 (with iptables disabled at target) - worked

Why is this a routing issue on the Gentoo box?

Certainly I could have a routing issue on ALL machines I suppose. I
set all machines up the same way, or as close as I could with scripts
all being a bit different, and some boxes are fixed IP and one box was
DHCP from the router. But why should disabling iptables on an FC2 box
have 'fixed' a routing issue on a Gentoo box?

Thanks!
Mark
