Subject: [LARTC] Error in "15.10 Example of full nat solution with QoS"?
Date: Thu, 06 Oct 2005 01:30:54 +0000	[thread overview]
Message-ID: <91740-22005104613054248@earnware.com> (raw)

Near the end of section 15.10, the following commands are shown for prioritizing SYN packets:

   iptables -t mangle -I PREROUTING -p tcp -m tcp --tcp-flags SYN,RST,ACK SYN -j MARK --set-mark 0x1
   iptables -t mangle -I PREROUTING -p tcp -m tcp --tcp-flags SYN,RST,ACK SYN -j RETURN

Shouldn't the "-I" option really be "-A"? Like so:

   iptables -t mangle -A PREROUTING -p tcp -m tcp --tcp-flags SYN,RST,ACK SYN -j MARK --set-mark 0x1
   iptables -t mangle -A PREROUTING -p tcp -m tcp --tcp-flags SYN,RST,ACK SYN -j RETURN

Won't using "-I" cause these entries to be inserted at the top of the chain, putting the RETURN before the MARK is set? Maybe I'm missing something.
