Hi, A simple quesiton. I want to nat few ports from my Linux server to windows machine. I have a seperate IP for it. I want to allow users to connect to port 21, 80, 8443 of the windows machine from outside world as well as LAN users ( the windows box will be in DMZ). Do I write a seperate command for each port? I am unable to use multiple ports at a time. Can someone give an example? Also, does RELATED & ESTABLISHED rules in FORWARD and INPUT chains cover this too? With warm regards, -Payal
