Minecraft CurseForge

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!

use this link https://duckduckgo.com/?q=whats my ip&t=lm&atb=v40-7&ia=answer instead - or speedtest.net, whatsmyip.com etc etc

thx for helping me learn the ip thing but I also need to know how to make the server run it make it work with the mods etc.

all you need to do is to set up a minecraft server (vanilla) and then install forge on top of it: http://minecraft.gamepedia.com/Tutorials/Setting_up_a_Minecraft_Forge_server

now you need copy the config and mods folders of your modpack's .minecraft folder to the server's .minecraft, and you're done.
