How to Open Port Windows in Windows Firewall

Why Open Port in Windows Firewall?

Opening a port is needed when:

• Hosting a game server
• Allowing remote management tools
• Running software that requires a specific port

Common examples include HTTP (80), HTTPS (443), and custom app ports.

Steps to Open Port in Windows Firewall

Step 1: Open Windows Firewall with Advanced Security

1. Open Server Manager.
2. Go to Tools → Windows Firewall with Advanced Security.
   

Step 2: Create a New Inbound Rule

1. In the left panel, click Inbound Rules.
2. On the right, click New Rule….
   
3. Choose Port as the rule type and click Next. This tells Windows you want to open a TCP or UDP port.
   

Step 3: Configure Protocol, Port, and Action

1. Select TCP or UDP depending on your application. TCP is the most common.
2. Choose Specific local ports and enter the Specific local ports (e.g., 1093).
   
3. Select Allow the connection and click Next.
   
4. Apply the rule to Domain, Private, and Public profiles.
   • Choose Domain, Private, and Public (check all).
   • Click Next.
     

Step 4: Name and Test the Rule

1. Give the rule a clear name like Allow TCP 1093. Then click Finish.
   
2. Open PowerShell to test whether the port is open using:

Test-NetConnection -ComputerName localhost -Port 1093

Summary

You’ve successfully:

• Added a port to Windows Firewall
• Allowed it for TCP or UDP
• Applied it to all profiles
