In case you are setting up a Web Server like WAMP/XAMPP, the default HTTP Port Number is 80 of TCP

Click “Save/Apply”.

Your port should be forwarded successfully now!

As of March, 2015 PTCL has blocked port forwarding for Dynamic IP DSL connections. For Port Forwarding to work, you must order Static IP from PTCL.
