Subject: Multiple port-fwd on same port  based on src IP
Date: Wed, 20 Sep 2006 14:38:49 -0400	[thread overview]
Message-ID: <45118AB9.8080104@samera.com.py> (raw)

Hi,
I wonder if I can use multiple port forwarding rules to the same IP/Port 
based
on the src IP and forwarding to different internal IPs

It should be something like this:
iptables -t nat -A PREROUTING -p tcp -s CLIENT1_IP -d INET_IP --dport 
1234 -j DNAT --to 192.168.1.1:1234
iptables -t nat -A PREROUTING -p tcp -s CLIENT2_IP -d INET_IP --dport 
1234 -j DNAT --to 192.168.1.2:1234
iptables -t nat -A PREROUTING -p tcp -s CLIENT3_IP -d INET_IP --dport 
1234 -j DNAT --to 192.168.1.3:1234
...

Will it work? Or should I configure some sort of tcp proxy.?

Thanks
Oliver
