How to share open server on windows server 2012?

Question

Domain Name System

We bought a VDS server with virtualization on windows server 2012 (it was necessary). I installed open server on it, because I read articles that you can share it on the Internet. In the settings, I specified a static ip assigned to the server. The domain was bought on reg.ru and is already attached to the hosting dns server in your personal account. On the server itself, in the open server settings, I specified the static ip of the server and added a folder with the name of the purchased domain. But nothing was shared and the server still works only on the machine itself and is not shared on the Internet. Maybe I missed something or you shouldn't share open server at all? It's just convenient)))
