Windows Server 2012 Port Forward for Specifc Host

Question

I am trying to have a specific host be redirected to another port when trying to access a service on port 80.

So, when the client (192.168.1.22) requests a connection to the server (192.168.1.10) on port 80 I would like the server to redirect the request to another port (9080).

Is this something that can be done? I can do it with a custom firewall rule in Linux (iptables) but I need to do this with Windows.

So, client connects to port 80 on the server and is redirected to port 9080. All other clients connect per usual (port 80).

Answer 1

You'll need to use the console:

netsh interface portproxy add v4tov4 listenport={number outside} connectport={port inside} connectaddress={127.0.0.1/destination IP}

Answer 2

Yes. Yes you can. Take a look at the rule scope, specifically look for the section titled: "Which remote IP address does this rule match"

From there it's trivial to make the firewall action do what you want by forwarding that client to another port.
