Understanding the "ports are open" problem

A port on the router (also called "a port forwarding") means that a port on a device on your network is forwarded to a port on the router. This allows computers outside of your network to access resources on computers on your network. You might want to do this for the following reasons:

  • Some games want to open a port to enable some features.
  • A network storage device lets you access your files from anywhere if you open a port.
  • A computer in your home can be managed remotely when you open a port.

Opening a port on your router is risky. Your computer resources are in the world. Only the security system on the service that you are available to is keeping the bad guys out. We recommend that you do not open any ports on your router unless you really understand the implications and take the right precautions.

What's the risk of not fixing this problem?

So leaving ports on your router open is trouble loading. Hackers can easily scan your network to look for open ports. When they find open ports, they try to exploit them. A hacker who enters your network through an open port can then access other resources on the network.

If a port is open on the router and you don't know how it was opened, you must have other network security issues. Recommendation: Check all security aspects of all devices running on your home network.

Manufacturer documentation

It is often a good idea to study the router documentation to learn how to troubleshoot problems. Go to the manufacturer's support website where you can download documentation.

Fixed how the "ports are open" problem

Step 1: log into your router

You use a web browser to interact with your router and troubleshoot its configuration problems. Before you can interact with your browser, however, you need to log into it. RouterCheck will give you detailed instructions on how to log into your router.

Step 2: When you log in successfully, the router's home page will open.

Step 3: Navigate to the Ports page.

Want to find a page that allows you to open ports on your router. The page name can be similar to:

  • Port settings
  • Firewall
  • Port forwarding

Navigate to this page by clicking on the appropriate menu items and buttons.

Step 4: If you are successful, your router ports page will open.

Step 5: remove all open ports.

See a list of ports forwarded to your router by a device on your network. The list includes the IP address of the forwarding device and the corresponding port. Verify that there is a control to delete the open port. If there is one, delete it.

Step 6: Run RouterCheck again.

Now that you have resolved your problem, run RouterCheck again to make sure that you really have resolved the problem.
