This is a bad thing. With 2 collision domains on one flat network, you
will have a lot more collisions and other hard to diagnose issues.
Additionally, security is out the window. You can get into the guts of
m0n0wall and make this happen, but it is not recommended. An additioanl
nic or vlans is the best way to go.
