-> uname -a Linux syspeo 2.6.23.jml-054 #1 SMP PREEMPT Thu Oct 11 22:32:06 CEST 2007 i686 GNU/Linux -> dpkg -l |grep libc6 ii libc6 2.3.6.ds1-13 GNU C Library: Shared libraries I would like to use iptables for igmp procotol. It seems this protocol is well known by iptables, because when inserting following command : sudo iptables \ --insert OUTPUT \ --protocol igmp \ --jump ACCEPT \ --out-interface eth1 \ --destination IGMP.MCAST.NET no error is returned by iptables. But, when dumping output tables from iptables, the protocol is not known and it is not possible to make the difference bettween a 'all protocol' or a 'igmp protocol' filter. -> sudo iptables --verbose --line-number --numeric --list OUTPUT |grep -i '224.' 1 0 0 ACCEPT 2 -- * eth1 0.0.0.0/0 224.0.0.22 best regards --
