[np] Thanks for the response but as I mentioned in my post I am aware that
iptables has this functionality. My question was relating to ipchains. I'm
pretty sure it doesn't as I don't seem to be able to find any reference to
it in R.L.Zieglers 'Linux Firewalls' but thought I would just check with the
group to make sure.
You can't filter packets based on MAC addresses with ipchains!
