In certain situations, you may need to open up one or more ports for the incoming connections in the Windows 8 Firewall.
I’ve experienced such a situation and explained it in another article IIS Error: Unable to read the value for the given section: AppSettings. If you have come across such a situation, then you can follow the below steps to open up one or many ports in Windows Firewall.
Steps for opening port in Windows 8 Firewall:
- Go to Windows 8 Start Screen.
- Type in the word firewall.
- On typing the search screen will be opened and displayed the results from the Apps by default. In the search result panel, you can see the App Windows Firewall with Advanced…
- Click on Windows Firewall with Advanced… in the search result to launch the Windows Firewall with Advanced Security screen.
- In the advanced screen, click on the Inbound Rules at the left panel.
- Click the New Rule… at the right panel.
- In the New Inbound Rule Wizard, Select Port and click Next.
- Select either TCP or UDP and specify the local port to be opened. Now click Next.
- Select Allow the connection and click Next.
- If you want to open up the port for the connection only if they are secure, then select the option Allow the connection if it is secure.
- If you want to block the incoming connection through this port, then select Block the connection.
- Select when the rule should apply (Domain, Private or Public) and click Next.
- Now enter the name for the new rule and description and click Finish.
- New Rule is created, and you can see it in the Inbound Rule List.
- If you want to modify the rule, double-click the rule to open the properties screen. Property screen will allow you to edit all the properties you have entered while creating the rule.
