Hi,
From the outset, i.e. around 2003, Wampserver has been a
local Apache, PHP, MySQL/MariaDB development server, i.e. a Windows-based Web development platform for dynamic Web applications, without the need for Internet access.
You won't be able to access Wampserver from the outside.
However, you will be able to access your correctly configured VirtualHost. And this external access can only be made from a PC other than the one on which Wampserver is installed.
Note: Don't put "Require all granted" anywhere and everywhere without knowing what you're doing.
I don't use Wampserver from the outside, perhaps others can give you solutions.
