Subject: need assistence for PREROUTING
Date: Tue, 11 Jul 2006 01:43:56 +0200	[thread overview]
Message-ID: <200607110143.56894.fvgi242ss@wlanhacking.de> (raw)

I have a webserver/firewall behind a dsl-router.
The router opens port 80,...,...,4444.

machine 1:  192.168.178.112 + Firewall + Webserver Port 80, 1 Nic
machine 2:  192.168.178.32  + Webserver Port 80, 1 Nic

Now i want machine 1 to redirect all requests on Port 4444 to Port 
80 machine 2.


The following does not work:

$IPTABLES -t nat -A PREROUTING -i $ETH -p tcp --sport 
$UNPRIVPORTS --dport 4444 -d xxx.xxx.xxx.xxx -j DNAT --t
o-destination 192.168.178.32

$IPTABLES -A FORWARD -i $ETH -o $ETH --p tcp --sport $UNPRIVPORTS -d 
192.168.178.32 --dport 80 -m state --state NEW -j
 ACCEPT

$IPTABLES -A FORWARD -i $ETH -o $ETH -m state --state 
ETABLISHED,RELATED -j ACCEPT

Any hints?

Thanx.
