This document provides information on how to setup a transparent caching
HTTP proxy server using only Linux and squid.

<sect1>What if I want to redirect packets generated on the squid box as well?
<p>
I am aware that a number of people are using squid and Transparent Proxy
in small home networks. In that case, the squid box happens to be a
personal machine as well, so they would like to redirect packets generated
from the local web browser. Thus, an additional command is needed.

<item>iptables -t nat -A OUTPUT -p tcp --dport 80 -j REDIRECT --to-port 3128
</itemize>
<p>Note the the chain used is different (PREROUTING is for packets coming
in from other boxen, OUTPUT is for locally generated packets) and I that I
have omitted the interface (so packets going out any interface will be
redirected. If you have multiple interfaces, you could probably add the
interface specification back in to only redirect packets going out certain
interfaces).
