In this example I’m going to allow all traffic requesting port 80 (the default HTTP “web” port) through.
Open a Port in Windows 7’s Firewall
- Open Control Panel from the Start menu.
- Select Windows Firewall.
[1]Note: If Windows Firewall is not available, change View by to Large icons at the top right of the Control Panel window.
- Select Advanced settings in the left column of the Windows Firewall window.
[2] - Select Inbound Rules in the left column of the Windows Firewall with Advanced Security window.
[3]Note: You can prevent outbound traffic by selecting Outbound Rules.
- Select New Rule in the right column.
[4] - Select Port in the New Inbound Rule Wizard and then click Next.
[5] - Select which protocol this rule will apply to (TCP or UDP), select Specific local ports, type a port number (80), port numbers (80,81), or a range of port numbers (5000-5010) and then click Next.
[6] - Select Allow the connection and then click Next.
[7] - Select when this rule applies (check all of them for the port to always stay open) and then click Next.
[8] - Give this rule a name and then click Finish to add the new rule.
[9]
The port is now open and ready to be used.
