Man, that was my next question!... NOT! :-0 How in the hell did that
get turned on? Anyway, glad you found it. (I've only got three hairs
left.)

By the way, using iptables on a machine behind a firewall you control is
a bit redundant. If you are a bit paranoid, you could use it to control
which ports are used by applications on localhost and potentially
prevent a trojan from openning a port on your machine. I personally
wouldn't go to such lengths, but it could prove to be usefull. The
reasons I asked where the behaviour and the fact that RH and SuSe both
default to setting one up on install.
