Subject: Order of match extensions
Date: Thu, 06 Oct 2011 21:55:44 +0100 [thread overview]
Message-ID: <1317934544.26402.2370.camel@andybev-desktop> (raw)
Hi,
Does the order of match extensions matter for iptables rules? Can
someone explain why the following 2 rules produce different results:
1. Matches lots of packets as expected:
iptables -t mangle -A FORWARD -i eth0 -m mark ! --mark 99 \
-m state --state NEW -m statistic --mode nth --every 1 -j LOG
2. Does not match any packets:
iptables -t mangle -A FORWARD -i eth0 -m state --state NEW \
-m statistic --mode nth --every 1 -m mark ! --mark 99 -j LOG
The only difference is the place of the "mark" match (either at the end
or the beginning).
(Debian iptables v1.4.8)
Andy
