How to make my server accessible from other networks?

I can access my GitLab server from the devices connected by the same router, but not from other devices. Apparently, using the public IP of my host computer doesnt help the situation either. How can I access the repos from other networks? I know my router IP and subnet and all network related data. I havent set up port forwarding and the


is set as the IP itself… like and not like

Expecting a fast reply :slight_smile:
