you might also look at APF + BFD as it works as well. Both solutions
are intended for the server and not for a remote host, however you
could probably work around this with a small shell script.
This does beg the question, why are you wanting to ban the IP's on the
router box as opposed to the machine being targeted? The whole point
of a router is to route traffic, not enforce firewall policy. This
would be better handled by a firewall of all things, be it a hardware
appliance (ASA, PIX, Juniper HSC) or iptables on the machine itself.
You might keep in mind that the more firewall rules you add to the
router the slower the network will become as all packets have to be
checked against all rules. Just my opinion ;)
