Starting Home System with a Firewall
I'm a beginner to Unix System Administration and I'd like to start first by having a server setup as a firewall. What would be a good distro to do this with? I'll be running it on an old computer. I plan on using command line only with this box.
Also, where can I start reading about doing this?
Currently, there will only be workstations under (is that the correct term?) this firewall.
Once I get my hands on more boxes though I plan on setting up some more servers.

APF(1) General Commands Manual APF(1)
NAME
apf - easy iptables based firewall system
SYNOPSIS
apf
DESCRIPTION
This manual page documents briefly the apf command. This manual page was written for the Debian distribution because the original program
does not have a manual page.
Advanced Policy Firewall (APF) is an iptables (netfilter) based firewall system designed around the essential needs of today's Internet
deployed servers and the unique needs of custom deployed Linux installations. The configuration of APF is designed to be very informative
and present the user with an easy to follow process, from top to bottom of the configuration file. The management of APF on a day-to-day
basis is conducted from the command line with the 'apf' command, which includes detailed usage information and all the features one would
expect from a current and forward thinking firewall solution.
OPTIONS
apf follow the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is included below.
-s|--start
load all firewall rules
-r|--restart
stop (flush) & reload firewall rules
-l|--list
list all firewall rules
-t|--status
output firewall status log
-e|--refresh

-a <HOST CMT|--allow <HOST COMMENT>

-d <HOST CMT|--deny <HOST COMMENT>

-u <HOST>|--remove <HOST>
