This is the weirdest bit. I set it to high...but it doesn't do anything.
/sbin/ipchains -L says:

Chain output (policy ACCEPT):

In other words, accept anything from anywhere. In effect, there is no
firewall that I can see. I'll rename /etc/rc.d/rc5.d/S80ipchains and
reboot so that it's disabled completely. It's unnecessary anyway, I'm
not routing for anyone, this is an end-user desktop.

Perhaps iptables or your kernel needs to be upgraded.
