I can't connect to my WAMP site using the external IP. What to do?

Question

Network administration

Localhost is working properly, there is a connection to the local network . All ports are open, only port 80 for some reason is shown as closed in PFP, the rest, with the same manipulations, are open, TCP and UDP. When I try to connect via IP, chrome writes "Waiting for site.ru" from the bottom

Question: How to connect to my server from another machine using my external IP

Note: The rest of the ports are definitely open, the game servers are working properly, I don't know port 80 ... Explain pliz "on the fingers"
Note 2: IP Dynamic, the provider does not block ports

Answer 1

Let's start with the basics - are you sure that you have a white and not dynamic IP?
Next, what is your network layout? If there is a NAT, is it configured to forward port 80 (by the way, it would be time to use SSL and port 443 already).
Does your ISP allow privileged ports?
