should be setting up an ethernet bridge.
Yes, a bridge is not routing. but how do you route between two interfaces on the same subnet? AFAIK you can't, hence requiring a bridge.
Per default, bridging will let anything through, unless traffic is filtered in some way.
Yes, bridging allows everything through as if the device were simply a piece of wire. There are some apps that will allow you to filter this traffic and set up rules. I used http://ebtables.sourceforge.net/ ebtables to do this and it worked like a bomb. Similar chain string setup as iptables, this made it fairly simple to pick up and run.
