Subject: multiport needs `-p tcp', `-p udp' - Why?
Date: Sat, 27 Feb 2010 10:03:15 -0500 [thread overview]
Message-ID: <4B893433.7020401@gatworks.com> (raw)
In order to get to the chain, the protocol, as well as the interface
must match. PRE_UDP if already filtered for "-p udp" . So why does
multiport require another check for -p udp? Does it really need to have
that option in order for it to work?
> + /sbin/iptables -t filter -N PRE_UDP
> + /sbin/iptables -t filter -A INPUT -i eth1 -p udp -j PRE_UDP
> + /sbin/iptables -t filter -A PRE_UDP -m multiport --dport 137,138,139,512,514,515,1433,1434 -j DROP
> iptables v1.4.5: multiport needs `-p tcp', `-p udp', `-p udplite', `-p sctp' or `-p dccp'
> Try `iptables -h' or 'iptables --help' for more information.
