The Re-Volt Hideout

I am a member of a group of new players to Re-Volt. We have followed the multiplayer instructions provided and are still unable to connect with one another. All running the same RVGL and RV House. All green names in the chat room of RV House. A couple hosts have already forwarded the ports as instructed, even if there seems to be a couple sets of instructions out there for this.

When the server is launched everyone just gets stuck on the main splash screen of the game after the connection times out. Direct IP connection times out as well. Assuming we use the public IP typed directly into the menu after clicking join.

Any tips or tricks to what we are doing wrong?

The host needs to forward port UDP 2310.
Then it will work.
