Subject: Filter out broadcast messages
Date: Wed, 07 Jan 2004 14:44:42 -0700	[thread overview]
Message-ID: <BAY10-F77TIFprhMOgR0003cd8a@hotmail.com> (raw)

Hi,

I would like to filter out all broadcast messages.  The packets could come 
from 255.255.255.255 or multiple other addresses of the form 10.*.*.255.  
What kind of syntax do I use to DROP these packets?  The line below will 
filter out packets from 255.255.255.255 but I'm not sure what syntax to use 
to DROP the other adresses.

iptables -A INPUT -d 255.255.255.255 -p udp -j DROP

Regards,
GJ
