Well, I'm using a 2.2.20 kernel (ipchains), but I dont think there is
any difference between ipchains and iptables here. I have been using
Squid already, but I don't know if it can block referrer information.
The issue is that I want a minimum of servers on this firewall, a
minimum of "holes" and a minimum of information going out. I am really
trying to put up a "zen" and invisible system. I was just thinking of a
command to add in the firewall script to do this.

Yes, I know that a lot of web sites are using such information for
statistics and so on. For me it's mainly a privacy issue. I want to give
away as little information as possible while surfing, and I even think
that this is a good principle...
