So right now I'm using a custom mod pack that someone made but I wanna play it with friends. My server knowledge goes as far as being able to make the server but not connect other people. And I can only make Vanilla servers. So I'm afraid I'm gonna need a lot of help. I need the server to be able to connect with people not in the same internet too. (such as someone using 1's house internet and me using another internet)
i dont know how to set up a modpack launcher, but if you run the server on your pc, all you need to do is find out your ip adress and let others connect to it. watch out, the ip displayed in your network manager is your ip in your home network, but not your ip in the internet!
