I do that with my P100, 40M RAM, 2 NICs. I use LEAF (see my .sig).

Some PCs assign eth0/eth1 based on IRQ used, or by the higher MAC address
of the NIC (I'm told). Actually, tho, as long as you know which card is
which, and label them accordingly, it doesn't really matter, right? The
firewall rules will say things like "forward from eth1 to eth0" (presuming
eth1 is LAN, and eth0 is WAN). As long as the right cable is in the right
NIC, that's all you want. And you can test which is which by PINGing a LAN
address with cable in one NIC. If you get a response, that's the internal
NIC. If not, it's the WAN NIC. :-)
