Service(s) languages are: NodeJs, Lua, Php, C.

This time we’ll be running the game network using Wireguard, not OpenVPN. Simple how-to:

1. Install wireguard, instructions can be found here: https://www.wireguard.com/install/.

2. You’ll be given the config file (teamN_M.conf). All former constraints are applicable as well, so each configuration file can be used by one teammate only. To connect, run

wg-quick up <file>

on linux in terminal, or import the file into the native app on macOS or Windows. macOS also has wireguard-tools package with wg-quick command in Homebrew.

3. To disconnect, run

wg-quick down <file>
