Joining MP over a 4g LTE network

[sovietkiller]

My friend is trying to join our MP game however it always gives him the connection error message. He has also tried to connect to a dedicated public MP game and it will do the same thing. Even when ours and his firewalls are turned off we cannot get it to connect, he also gets the same issue when trying to use Evolve or Hamachi. He can play CSGO and Battlefield 1 just fine but i think it has to do with VPN or tunneling where the issue may be. Does anyone know why, when using a 4G LTE network, he cannot connect?

No he cannot just use another method of connecting to the internet so dont ask.

The log you posted shows a user creating a server and closing it again five minutes later. Post the logs of client and server trying to establish connection with each other.

I think it fails because of the 4g LTE network your friend uses.

Factorio uses NAT punching to create a port and keeps it active with periodic keepalive packets explained here

Now i did a quick google on 4g nat punching and found this.

This is what i found with a quick google and dont know if it is actually correct. Incase I'm wrong please correct me.

NAT punching is used to determine the external IP/Port of the server, it is not used on the client side.
