The best way to do this is on the squid server using iptables, but my
knowledge of iptables is limited and I can't find out how to do this.
How do I tell iptables that IP address should just be passed through the
server and not sent to squid?
Currently if I take an IP address out of the ip rule for forwarding to squid
the web requests from that IP address just fail since the server doesn't run
web and doesn't know that it should just forwarded out into the Internet.



Maybe something like:

/sbin/iptables -A PREROUTING -t nat -p tcp -s 192.168.1.0/20 --dport 80 -j SQUID
/sbin/iptables -A SQUID -d <some ip> -j RETURN
/sbin/iptables -A SQUID -d <some ip> -j RETURN
/sbin/iptables -A SQUID -d <some ip> -j RETURN
/sbin/iptables -A SQUID -j DNAT --to <IP ETH0:1>:3128


does what you want?
