No need to use masquerading at all if you only intend your clients to 
have internet access exclusively through Squid, and your firewall should 
not be doing any packet routing at all ( echo "0" 
 >/proc/sys/net/ipv4/ip_forward )

You should look into using iptables with a 2.4 kernel rather than 
ipchains - iptables looks a little harder but works out way easier.

Paul.
