	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.
