Config Files and Port Forwarding: Proof of a Working Boiii Server Setup
By Marcus Vance
Hosting begins within your primary Black Ops 3 root installation folder (typically located at Steam/steamapps/common/Call of Duty Black Ops III). You will need a clean, verified installation alongside the latest BOiii executable from the community-maintained source.
Inside the game directory, create a dedicated folder structure to hold custom parameters:
<pre>Call of Duty Black Ops III/
├── boiii.exe
├── boiii/
│ ├── server.cfg
│ └── dedicated.bat
└── zone/
</pre>
Launch boiii.exe once to let the binary generate default folders, then close it. Create a new text file in the primary directory, name it dedicated.bat, and set its execution script to launch the binary in server mode. The core command-line argument tells the client not to boot the full graphical user interface, reducing system memory usage by roughly 65%:
<pre>boiii.exe -dedicated -boss +set net_port 27017 +exec server.cfg
</pre>
The -dedicated flag suppresses the game's rendering pipeline, while +set netport 27017 assigns the listening socket. If you intend to run custom Zombies hosting instead of standard multiplayer, append +set fsgame "mods/mod_name" to point directly to installed community maps or gameplay overhauls.
