Your best to just dual home the Linux box and connect your LAN machines with
a switch. Otherwise all your internal traffic has to route through the
linux box as opposed to just the switch. Very inefficient! If you want a
DMZ for servers you can tri-home the machine. Putting each computer on
seperate nics on the Linux box is inefficent for LAN traffic and can be a
pain in the ass as far as configuring IPTables is concerned.
