Windows 10 has built-in support for port forwarding but it's not exposed in the Settings interface. Port forwarding allows you to access network resources as if they're hosted on your local machine, which can be helpful when working on a LAN (local area network) or developing with web servers.
In this guide, we'll walk you through adding your own port forwarding rule. For the purposes of this guide, we'll add a rule which routes the address "http://127.0.0.1:9000" to "http://192.168.0.10:80". You'll then be able to visit "http://127.0.0.1:9000" in a browser and view what you would have seen if you'd accessed "http://192.168.0.10:80" directly.
Adding the rule requires use of the command prompt. You'll need to be logged in as an administrator, too. Begin by typing "cmd" into the Start menu. Click the first search result while holding the Control and Shift keys to launch Command Prompt as an administrator.
Next, you'll use the "netsh" command to configure the port-forwarding rule. It's a somewhat long-winded command, so be sure to type it as you see below.
netsh interface portproxy add v4tov4 listenaddress=127.0.0.1 listenport=9000 connectaddress=192.168.0.10 connectport=80
Notice how the values given for "listenaddress", "listenport", "connectaddress" and "connectport" correspond to those we stated earlier. You'll need to make adjustments here to suit the rule you're adding. For example, if you want to route to port 8888 on the device with IP 192.168.0.1, you'd use these values for the "connectport" and "connectaddress" respectively.
When you press enter, the rule will be added and applied immediately. Try visiting the listening address and port in your browser – you should see the content being served by the connect address and port.
When it comes time to remove the rule, return to an administrator command prompt and use the following command:
netsh interface portproxy delete v4tov4 listenaddress=127.0.0.1 listenport=9000
Again, you'll need to adjust the specified listening address and port to match the values you're using. The rule will be deleted immediately and will no longer apply to new network requests.
