I got the above setup based on my understanding of the handbook, so > forgive me if I didn't understand it correctly :) I believe the actual fault is that you don't understand how networks are done, based on the /etc/rc.conf entries you've listed above. I suggest that you pick up Computer Networks: A System Approach by Peterson and Davie to pick up a basic idea of how networking and routing works, and maybe consult <http://en.wikipedia.org/wiki/Classful_network>; as a basis for planning out how things will be done, in particular with network addresses. Providing netstat -nr" output would be beneficial as well when troubleshooting issues with routing, as well as any firewall rules you have in place. -Garrett
