I've just been playing around with this. I bet this is a totally
insecure solution for use in a firewall (if it even works, I've haven't
tested it fully yet) but under Linux with IP aliasing support built into
the kernel you can specify multiple IP's to a single nic using:

eth0:0 
address 192.168.1.etc

eth0:1
address 10.0.0.etc

Could you not just assign the nic different IP's and have each IP on a
different IP address range?

This is a assuming you want some mini-itx machine with 1 pci slot to
serve multiple network segments somehow and are to cheap to buy a real
multi network interface on a single PCI card ;)

I look forward to someone ripping that suggestion apart :)
