Well, you'll end up using iptables anyway right?  If you really want
to -force- folks to get out through a proxy, that is.  Since you
mention that the router is a gentoo box, should be an easy one.

Tough to setup Squid? Naw.  Of course, it's like most things, we don't
know much about your network or the scope of your requirements.  For
our use case, we needed the following:

-forced access through the proxy
-website URL blacklisting and custom redirection based on massive regex lists
--Automated notification on certain 'violations'
-user account login to the proxy before internet access
-username tied to all proxy logs
-'manager' access to log data via nifty graphs on a web server

So, ours took some time.  :)

Ya, I know these folks were uuber paranoid, and wanted the ability to
nab folks for what they felt like was inappropriate internet usage...
Anyway your situation sounds much simpler.  So simple in fact that
just a few tweaks to the default squid.conf can provide you with a
functional config.

There are heaps of doco out there on configuring Squid, so you should
have a look and see what you think.  You can easily get a little test
proxy going on a desktop or laptop to try it out.  :-)

Hope this helps!
