NAT -- Virtual Servers Setup Port 80

Hello, I want to make my website public but i am having problems with PTCL NAT settings

So, it shows this when I use port 80 and when I try to open my ip it doesn't work


But, using external port 8080 works just fine, except that the ip now is

Obviously, I do not want the external port to be 8080 as I wouldn't be able to setup a domain with that.

Please help me in this matter, The ideal solution will be to somehow move the port of PTCL's settings page to 8080.

But I was unable to find such option in settings
