So me and my friend wanted to create a server and connect to each other through hamachi, however the connection between us was relayed. However, when a third person joined our network, both of us had a direct tunnel with him. When the person I had a relayed connection with tried using an LTE hotspot on his computer, it became a direct tunnel with both me and the third person. I believe the issue has something to do with his router, but im not exactly sure what it is since the relayed connection is just between me and him and he doesn't have this issue with anyone else who connects. If someone could help me out that would be greatly appreciated.
