Hey, I want to port forward a port from my linux server to another box in my local network, i tried some iptables command but it didn't work.
How should i forward this.

I am a friend of Xeross, and we are working together on this problem.

Let me explain it a bit better:

We currently have this network layout:

I know it isn't very wise to connect servers with WiFi, but this was the only way.

We have forwarded every port in the LinkSys router to the TZXS01 server. This is the server we want to configure.

We have port 7711 listening on TZXS02, so we want to direct incoming trafic on port 7711 to 192.168.1.201:7711.

Problem is, we only got one network interface: wlan0.

We have tried to do this with iptables, but it didn't work out.

here is current iptables config:

Code:

root@TZXS01:~# iptables -L ; iptables -t nat -L
Chain INPUT (policy ACCEPT)
target     prot opt source               destination

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination
Chain PREROUTING (policy ACCEPT)
target     prot opt source               destination
DNAT       tcp  --  anywhere             535697DF.cable.casema.nl tcp dpt:7711 to:192.168.1.201:7711

Chain POSTROUTING (policy ACCEPT)
target     prot opt source               destination
SNAT       tcp  --  192.168.1.201        anywhere            tcp spt:7711 to:83.86.151.223:7711

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination
