iptables Forwarding issue
I have been working on this for quite some time,
still have not find a solution.
have pc1 acts as firewall, pc2 has some services running on it
so i need to forward the request from firewall to the pc2 and the other way around.
i need 2 ports to be working like that
1 - 2260 for ssh (pc1) -> maps to 2260 on pc2
2 - 8091 for tomcat (pc1) -> maps to 8080 on pc2
my ssh works great here are the rules for ssh:
-A FORWARD -p tcp -i $WAN_IFace --destination-port 2260 --destination 192.168.1.10 -j ACCEPT
-t nat -A PREROUTING -p tcp -i $WAN_IFace --destination-port 2260 -j DNAT --to-destination 192.168.1.10:2260
$IPT -t nat -A PREROUTING -p tcp -i $Local_IFace --destination-port 2260 --destination $INET_ADDRESS -j DNAT --to-destination 192.168.1.10:2260
when I do the tomcat stuff i have this:
-A FORWARD -p tcp -i $WAN_IFace --destination-port 8080 --destination 192.168.1.10 -j ACCEPT
-t nat -A PREROUTING -p tcp -i $WAN_IFace --destination-port 8091 -j DNAT --to-destination 192.168.1.10:8080
-t nat -A PREROUTING -p tcp -i $Local_IFace --destination-port 8091 --destination $INET_ADDRESS -j DNAT --to-destination 192.168.1.10:8080
These rules look fine to me, but no matter what i do it does not work.
I know that the tomcat is running and listening to the port 8080, I also tried
forward to the port 80 just to make sure that its not tomcat causing it.
I hope someone can help me out.
thanks

Is it possible to run anything else on port 8080 just to make sure its not a fault on the client end?
Also is SELinux on?

Hi, I am a moron.
No the SElinux was off, that's first thing i checked.
There was ANOTHER! firewall in place that manages the local connections of the network that would not allow these ports to communicate. So my iptables as i expected were correct.
.. i guess classic id-10-t problem.
