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.
