Which means .. *ding* *ding* *ding* .. you'll have to install a proxy
firewall! I don't suppose those Cisco NAT's will do any good here will
they Paul? However, if you can't renumber the bad hosts or if you are
using RFC1918 numbers solely to protect yourself against having to
renumber when you change providers, then a NAT is a very handy solution to
use along with packet filtering.
