Re: Bad Traffic, Port

Are you running Snort on the IPTables machine?  If so even though you are
blocking port 0 traffic, I believe that Snort can still see the traffic
that is coming at the box.  So, you are blocking port 0 but Snort reads
the traffic off of libpcap before it is denied by IPTables.

Hallo,

well, i did this via IPTables; doesn`t work.

Well, if you check the SID,  it says to disallow UDP traffic on Port 0.
