 |
|
I know this has been talked about again and again, but a search on Google doesn't provide any clear, simple solutions to port forwarding under IPTables. This is the 'normal' port forwarding as in under NAT routers: port X on a machine routes to port Y on another machine behind the NAT, and traffic flows both ways (through NAT). How would I do this?

Lets suppose you want to port forward 4662 TCP (edk) to 192.168.0.50 and your router wan interface is ppp0:
| Code: | iptables -A FORWARD -i ppp0 -o ethX -p tcp --dport 4662 -j ACCEPT #This line only if you have a DROP, then ACCEPT policy.
iptables -A PREROUTING -p tcp --dport 4662 -i ppp0 -j DNAT --to 192.168.0.50:4662 #this one will do the trick |
Where ethX should be replaced with your lan network adapter name.
Regards.
