Am I barking up the wrong tree? Thanks all =)
It's clear, however, as others have pointed out it's far easier to block everything and then selectivily allow what you want to talk to you. How do you think iptables will react if you have say 20,000 entries in it? My guess is it will slow your machines down. Go the sensible route and block everything and permit the much smaller list of hosts to connect to you. _______________________________________________ Full-Disclosure - We believe in it.
