Fusion Tanknarok Multiplayer


I ve downloaded and created a build for Tanknarok, i took the resources from the unity asset store. So far the game looks great but being new to photon i have a question.

Since i was curious about the multiplayer i ve tryed to open two builds on local network and it worked just fine but when i ve send the build to my brother we could not make the game to connect over the internet.

I want to make the game to work multiplayer over the internet connection so i can test it with my brother. Is there a specific tutorial that i can follow and maybe install other dependencies?
