I need help setting up a server I am working with. I am not very knowledgeable in regards to Linux. With that in mind I have read several HOWTO's and I am convinced that SNAT is what I need to do this. What I am trying to do is I have to servers on two different T1's located on the same switch. I would like server1 (my Linux Server) to accept an incoming connecting via its IP address on T1(1) 12..22.81.18 on port 10025 and forward that request to server2(my Windows Mail Server) on T1(2) 204.250.113.2 on port 25 I have tried several combinations of iptables -t nat -A POSTROUTING -p tcp -o eth0 -j SNAT --dport 10025 --to 204.250.113.2:25 What am I doing wrong or am I looking at the wrong tool.
