Yes, it's possible. You mentioned using Dlink DE220 ISA's, I've built this identical router before. There is a floppy disk that comes with the card (you can also download it) that writes the IRQ/IO stuff into the firmware. It's kinda the same as using jumpers, but it uses software to flash the firmware instead. You need a DOS bootable disk to do this. Assign the cards some free pairs of IRQ/IO's (I usually use 10/300 and 5/220 because they're easy to remember) and set them up in /etc/conf.modules. Do an 'insmod ne2000.o irq=10,5 io=0x300,0x220' and voila, eth0 and eth1 appear. Two ifconfig's later and you have a router/firewall. Just remember to label the cards so you can tell which is your inside interface and which is outside :-) -Brian
