I'm trying to play The Hunter: Primal with some friends but since the game it's on Early Beta there are no Dedicated Servers so we have to set up our own.
Thing is the game requieres to open some ports

UDP 42303
UDP 8766

Supposedly I already opened the, but my friends still can't log in into the game.
Does anyone has a tutorial or knows how to open them for a Technicolor TG582n modem?
portforward.com does nothing :(
