Firewalling away the ads?

[DarkRyder]

I recently got my household set up behind a firewall (vanilla-sources + shorewall) and would like to use it to filter out known advertisers, but have not found a way to do so.

Shorewall has a "blacklist", but it appears to only work for incoming connections, while I want to block outgoing. Basically, I want to be able to set up something like ZoneAlarm's "Blocked Sites" on the firewall so I don't have to install and configure software on each of the systems behind it.

Any advice?

You could try this:

there are also possibilities to do that with squid

append to /etc/hosts :

of course you still have to do it on each machine, but at least there's no additional software required.

or, it would be pretty easy to convert into iptables rules...
