Spec me a firewall

[quackers]

I've been using zonealarm for years without any major problems, until recently when it's taken the decision to randomly block all internet traffic.

I know a lot of people say dont use a firewall if your behind a router etc, but i like being able to control what's going out of my system.

So whats the recommendations chaps? free and easy to use please

Thanks all
