If the router is an actual router (Like cisco / livingstone / etc), or
perhaps even linux routers, I believe for effecient routing you have to
route accross subnets ??

What you can do, perhaps is to assign eth0 and eth1 on the router different
IP addresses from your currently used IP block, and staticly route networks
over that.

Otherwise, you can devide your .224 subnet up and use an dedicated network
for your client computers, which route to the router, and your router and
the rest on an subnet which goes to the internet.
