Open A Port in Windows 7 Firewall

Automatically Log On To Windows XP


Windows 7’s firewall has been enhanced significantly since XP and Vista but with these enhancements have brought a more complicated interface and less user-friendly ways to customise the open ports and allowed applications.

This HOWTO tells you step by step how to make open a specific port using the built in wizard.

You may need to open ports for many reasons such as using a non-default port for Remote Desktop Connection (RDM), using your PC as a server for applications such as FTP or for gaming.

Here’s how to do it:


  1. Click Start button > Control Panel
  2. Click System and Security
  3. On the right, click Windows Firewall
  4. On the left, click Advanced Settings as show below

  11. Click Next > The Action screen should appear.
  12. Select the Allow the connection radio button as shown below > click Next

    It didn’t work. I’ve gone through all the steps twice and online port checking tools are showing the port is still closed.

      Could it be that your router is blocking the port and not Windows…online port checking tools generally can’t check if a Windows port is open until the router has been configured properly.

      In your router config, check your NAT section.
