Re: UDP Port 0 not blockable



well ... if you put a filter using iptables and you are using tcpdump (or
snort) to see if the packets are still coming in, of course that you'll see
that the packets are still coming in, if you are monitoring the fastethernet
(or ethernet) interface on your router, because tcpdump and/or snort are
capturing the packets BEFORE iptables. I hope I'm right :)
