I should have read your reply before sending mine off to Bascule. That was
better than my point-point reply.
The firewall as I have it set up does most all you mentioned. I opted for
the
easy way out and used the Linux Router Project, notably Charles Steinkulers
diskimages.
As for the bad form of running most all those things on one box. I agree,
however, as you saw its just a couple of workstations and a printer. Besides
the
ipchains, there is a dnscache, dhcp, ssh, dhclient and portsentry (for
grins).
