Actually you only need the PCI. I've both used a 486DX2-66 MB with PCI
and a P-100 PCI MB for my firewall. The IPCHAINS rules list is long,
about 100 entries. Each worked fine. I have 10/100 PCI NICs on each
link. It's a 3 NIC system with a DMZ for my web/DNS server. My DMZ
only talks at 10Mbps due to there only being a 10Mb HUB on it.
When setting up my firewall/router box I evicted the PCI graphics card
for an ISA one. I wanted the slot for the NIC. The disk on the box
is a lowly 100Mbyte IDE salvaged from a system I helped upgrade. I
have a stack of them laying around to use as replacements. I even
went as far as loading duplicates of my firewall setup on a couple of
them to serve as spares incase of failure.
As for the web server box, it got the better and larger hard disks,
but it's also a slow box. It all depends on how much dynamic content
you wish to dish out. My pages are mostly static. I can get by with
a wimpy system.
