Hello,

should ./kipfw <port0> <port1> and another ./kipfw <port0> <port2> work?

I want to have two filtered kipfw instances sharing the same WAN port.

So far I did a quick test lab and it worked, but since it's a lab
environment I don't know if I should expect other problems when I add it to
run in a real scenario.

What problems should I expect? Can they be minimized?

Basic stateless filtering only.
