If you have login access to your router, you can manually configure port settings. This isn't something you'll need very often, but it's useful to know how to do it in case you need it.

What is a port?

Ports are like house numbers. They're used to help direct packets and network traffic to specific applications and devices. Each application uses a unique port number.

Most port management happens automatically in the background, but sometimes you may need to manually adjust your port settings. This is especially common when setting up multiplayer servers for gaming on your home network. In cases like this, you may need to open a specific port.

Router Login

Routers can often be accessed using a web browser. You can use any device that has a browser, including smartphones. In most cases, you can use the router's IP address in the address bar. If you aren't sure what yours is, check out our guide on how to find your router IP address.

Once you reach the login screen, log in to the router. If this is your first time logging in, you will need the default login credentials. If you received the router from your ISP, contact them for the username and password. If you purchased your own router, check with the manufacturer.

Port Settings

Once you're logged in, look for settings designated for making port adjustments. The exact location will vary between models and manufacturers. You may need to look under advanced settings menus.

Change Port Settings

When you find port settings, take note of the existing configuration. You may want to save a screenshot of them before making any changes.

Make the changes you need for the port settings and look for an option to save them.

If you aren't able to make the changes or receive an error when trying, you may need support from the ISP or manufacturer. Try researching online for your router model. It's likely that other people have tried to open a port on the same router before and shared information about the process. Managing ports is a common router function and you can usually find tips for your router model online.
