I'm running with BungeeCord netwok and all my game servers are on Spigot 1.11.2 latest builds. I can use the /server command to go to any of the worlds, but it isn't clear how the Portals can find which world to go to. I'm using a centralized hub (world) where all users come in and from there, they can (or I'd like them to) go through a portal that connects to one of the other worlds. Same for the Nether Portals for each world and The End Portals.

My game servers are using the 127.0.0.1 address behind the bungeecord server listening on different Ports. Where is the configuration files that allows me to tell Multiverse-Core, Portals, NetherPortals, etc how to connect to the other worlds? Thanks!!
