This video tells us the method to open ports in Windows 7. Click on myu icon and go to 'Preferences'. Copy the port number from the resulting window. Go to 'Start', 'Control Panel' and 'System and Security'. Go to 'Windows Firewall' and 'Advanced Settings'. Go to 'Inbound Rules' and 'New Rule'. Click on 'Port' and select 'TCP' and 'Specific Local Port'. Type the port number in the text box. Click 'Next' and 'Allow Connection'. Press 'Next' twice and put the name in the space provided for it. Click on 'Next' and the inbound rule will be displayed. For outbound rules, repeat the same procedure selecting 'Outbound Rules' instead of 'Inbound Rules' and 'UDP' instead of 'TCP'. This opens the port.
