Subject: Filtering MAC addresses and Multicast
Date: Tue, 01 Aug 2006 10:35:50 +0200	[thread overview]
Message-ID: <44CF1266.5090109@estudiants.urv.cat> (raw)

Hello all,

I have a strange problem using iptables that had been reported yet in 
this list two years ago, but it has not been solved: 
http://lists.netfilter.org/pipermail/netfilter/2004-October/056506.html

I emulate a MANET on an Ethernet by adding iptables rules like these 
(filtering at MAC layer):

/sbin/iptables -t mangle -A PREROUTING -m mac --mac-source 
00:06:5B:12:C9:7A -j DROP
/sbin/iptables -t mangle -A PREROUTING -m mac --mac-source 
00:06:5B:13:4A:69 -j DROP

These rules drop Unicast traffic but they do not drop Multicast traffic.
How can I fix it?

Thank you in advance
Kind regards,
Gerard
