Well.. it does not actually matter which port Squid listens to. You
still need a redirection or the TCP stack won't accept the traffic and
instead tries to forward it to the real destination.

It works equally well using port 80 as port 3128, or 49765 for that
matters. No functional difference there.

There is one difference in that not runnig Suqid on port 80 allows you
to run a web server on port 80 on the same machine..
