Port forward to web server

peter zaher

I have Website published on IIS as http on port 8888.

I added it as Web Server and created business role add authentication method.

I can access the website on new port 8887 from Lan, when i tried to access the website using Public ip from wan didn't worked.

I tried to create DNAT for the new port but still face the same problem.

 

Regards,

Peter Zaher
