Subject: Problem with SNAT and same port number
Date: Mon, 23 Feb 2004 13:30:59 +1000 [thread overview]
Message-ID: <200402231330.59035.netfilter@serverguy.net> (raw)
Hi,
I am wanting to change the source address of outgoing packets that have a src
port of 53.
I have tried
/sbin/iptables -A POSTROUTING -p tcp -t nat -o bond0 --sport 53 -j SNAT
--to-source 192.168.0.1:53
This doesnt work, it seems to be that you cant SNAT to a port the same as the
original src port because
/sbin/iptables -A POSTROUTING -p tcp -t nat -o bond0 --sport 53 -j SNAT
--to-source 192.168.0.1
/sbin/iptables -A POSTROUTING -p tcp -t nat -o bond0 --sport 53 -j SNAT
--to-source 192.168.0.1:52
both works, but obviously not the same results as I wanted because the src
port is also changed.
Is there any other way to do what I am wanting??
TIA
