Port forwarding for a game server help

[scorpionking674 0]

Hello, how do i port forward? I need to run a game server with 6 ports for ark survival. It is a cluster server and the ports are as follow: Server 1 - 27015, 7777-7778 | Server 2 - 27016, 7779-7780. What all do i need to do here? I was unable to get any of these ports available on here and i just subscribed for airvpn.

Port forwarding works on a first come, first serve basis, so if someone already forwarded 27015 for example you won't be able to. You need to change those ports in ARK's config.
