How to forward IP-Port on Windows Machine

You need to open ports from the firewall and forward the packets using netsh command.

Opening Port(s) Access

To manually open a port, follow these steps:

1.    Click Start, and then click My Network Places.

2.    Under Network Tasks, click View Network Connections. (Or, right-click My Network Places on the desktop, and then click Properties.)

3.    Right-click the connection that you use for the Internet, and then click Properties.

4.    Click the Advanced tab, and then click Settings.

Note: If the Settings button is unavailable, ICF is not enabled on this connection, and you do not have to open any ports (because they are all already open).

5.    Click Add to open a new port.

6.    In the Description box, type a friendly name. For example, type File Sharing : Port 445.

7.    In the Name or IP address of the computer hosting this service on your network box, type 127.0.0.1.

Note: You can specify the IP address of an internal computer. But you typically will use 127.0.0.1.

8.    In the External port and Internal port boxes, type the port number. Generally, this number is the same.

9.    Click either TCP or UDP, and then click OK.

10.  Repeat steps 1 through 9 for each port that you want to open.

Forwarding Packets

Run the command given below to forward packets coming from a particular port to OUT_IP:OUT_PORT.

Delete previous forwarding rule

netsh interface portproxy delete v4tov4 listenport=PORT listenaddress=IP

Add a new forwarding rule

netsh interface portproxy add v4tov4 listenport=PORT listenaddress=IP connectport=OUT_PORT connectaddress=OUT_IP
