this could have already been posted / said but i think the main problem the the ports. Demi god auto detects open ports although trying this out it didnt actually change ports, ie it stayed on 6073, so i think the main problem is that, due to there being a peer to peer conection if somone doesnt have their port open the may cause you to not be able to connect to them thus resulting in that dissconnected from the NAT faccilitator.
