Are you playing a game or using an app that requires certain ports to be open? If you are using apps like BitTorrent clients, or multiplayer servers for games, they may require you to set up port forwarding. You may also need to set up port forwarding if you are trying to connect a server, or are using your computer as a server. While making changes to your router might sound intimidating, it's actually quick and easy! This wikiHow article teaches you how to set up port forwarding on your router.

Things You Should Know

Most routers have a firewall that blocks unwanted traffic to your network.
Port forwarding creates a special path that allows devices and apps to connect to the internet through the firewall.
You can create special rules for port forwarding using your router's web interface.

Setting Up Port Forwarding

Understand your router's interface. The user interface is going to be different for each router make and model. You may need to look around or check your user's manual/online documentation to find the Port Forwarding settings in your router's user interface. Use the default gateway address for your router to access your router's user interface on PC or Mac. For example, if you wanted to find the port forwarding section on a Linksys router, you would search for linksys port forwarding and look for your router's model number from there. Be prepared to think outside the box when looking for router page items; for example, if you don't see "Advanced" listed somewhere on your router's page, keep looking—don't just give up there.

Log in to your router's user interface. To do so, you will need to find the default gateway address for your router and enter it in a web browser. Then you will need to log in to the router's user interface using the admin username and password. If you have not changed the username and password, you will need to use the default username and password, which will be listed in your router's user manual or online documentation. If you are not sure how to find the default gateway address and access your router's user interface, see Accessing Your Router on Windows or Accessing Your Router on Mac.

Find the Port Forwarding section. Although each router's page will be slightly different, common menu labels for the section of settings that contains Port Forwarding are "Port Forwarding", "Applications", "Gaming", "Virtual Servers", "Firewall", and "Protected Setup" The following are where you can find the port forwarding settings for different router brands: Linksys — Click the Applications & Games (or Apps & Games) tab, and then click Single Port Forwarding to open a single port or Port Range Forwarding to open a range of multiple ports. . Netgear — Click Advanced Setup and then click Port Forwarding/Port Triggering or Ports - Custom Services. Belkin — Click Virtual Servers below the "Firewall" header in the menu to the left. Asus— Click WAN in the menu to the left and then click Virtual Server/Port Forwarding.

Find a port forwarding preset. Many routers will have a drop-down menu with pre-configured options for well-known applications. If you need to open ports for one of these applications, select it from the "Service Name" or "Application" (or similar) drop-down menu and then save your changes by clicking Save (or similar). For example, Minecraft is a common program for which people forward ports, so you might find a Minecraft setting here.

Create a custom entry. If the program you want to add is not listed, you will need to create a custom port forwarding entry. Each router will have a slightly different way of doing this, although the required information is the same for any router: Name or Description — Enter a name for the service (e.g., "Minecraft"). This isn't usually required, but it will help you keep track of your various port forwarding rules. Type or Service Type — This can be TCP, UDP, or both. If you aren't sure of which one to use, select Both or TCP/UDP. Inbound or Start — The first port number goes here. You should research your selected port number to make sure it isn't already taken by a specific application. Private or End — The second port number goes here. If you only want to open one port, enter the same port number here; if you wish to open a range of ports, type the number of the port at the end of the range into this text field (e.g., entering "3570" in the first field and "3580" in the second field would open ports 3570 through 3580).

Enter your computer's private IP address. This goes in the "Private IP" or "Device IP" field. You can find your private IP address on PC or on Mac. If your computer has a dynamic IP address that changes ever so often, you may need to assign your computer a static IP address to keep it from changing. Depending on your router, this text field may already be filled with your computer's IP address. If so, skip this step.

Save your settings. Click the Save or Apply button. If prompted, you'll also need to allow your router to restart in order for the changes to take effect. You may also have to check an "Enabled" or "On" box next to the forwarded port row.
