Me and my friends have been playing The Age of The Ring Mod online.
We can play with two players without any issue, but the three of us can never play together. I can connect with both of them, and they with me, but they can't connect amongst themselves. I've played with both of them, one at a time, without any issues on different ocasions.

Does anyone have the same problem, any idea why this is happening and what we can do to solve it?
