Forward data from multiple computers to an ip through intermediate server

[harwee]

Similar to proxy server but with port forwarding ?

Let us assume we have three computers(with different ip's) which want to send data to ip x.x.x.x, port:N,
I have developed a software to route these connections to server with ip xx.xx.xx, port:80 , now the server forwards requests from computers to ip x.x.x.x , port: N and receives data from xx.xx.xx.xx and sends the respective data requested to respective computers. Can this be achieved?? This can be achieved when a single computer and server is used but what can be done if there are multiple computers??

Update "Its not just a proxy server" it includes port forwarding

Sounds like you're just describing a basic proxy server.

I edited the post, I do know that this looks like a proxy server but can it should send data to specific port

I suppose it's technically possible. You're essentially describing port forwarding. For example your router can forward port 80 traffic to any other port if you wanted.

You can use iptables rules to set up the forwards.
