This setting specifies whether you are running a LAN- or Internet-visible game server. An Internet-visible game will be advertised on the master server browser, allowing online players to join your game easily. Note that, even if you set the game to LAN-only, online players will still be able to join if it is possible to reach server_port from the Internet, by adding it manually to their personal server lists.
The setting of lan_internet can be set to:
- 0 = internet-visible, advertised on master server list
- 1 = LAN-only, not advertised.
Note that the setting server_advertise also affects advertising to the master server list.
