What, if any, firewall do you have installed?

I had the same problem here when I (finally) got a wireless setup.  I 
tried a bunch of firewalls and and settled on arno-iptables-firewall
and privoxy.

Now I can surf the web and don't have many sites eating not only my 
bandwidth but also eating up my 5 Gig monthly allocation.
