Config Files and Port Forwarding: Proof of a Working Boiii Server Setup
By Marcus Vance
The heart of your setup is the server.cfg file, located in your boiii directory. If this file contains malformed syntax, the executable defaults to local loopback mode, preventing external traffic from joining.
Open the file with an editor like Notepad++ or VS Code and structure your baseline settings:
<pre>// Host Identity & Passwords
set livesteamserver_name "My Dedicated BOiii Match"
set g_password "" // Leave blank for public matches
set rcon_password "SecureAdminPass2026" // Remote administration key
// Match Environment
set sv_maxclients 8 // 4 for Zombies, up to 18 for MP
set sv_allowAnonymous 0
set scrgameallowkillcam 1
set party_maxplayers 8
// Zombies Baseline
set g_gametype "zclassic"
set uizmmapstart "zm_factory" // The Giant / Der Riese
// Network Sockets & Tick Stability
set svnetworkfps 30
set sv_minPing 0
set sv_maxPing 250
</pre>
Assigning an rconpassword is mandatory. Without it, you cannot restart broken rounds or kick disruptive players without killing the operating process via Windows Task Manager. For competitive multiplayer maps, adjust ggametype to tdm, dom, or sd, followed by the respective map file string (such as mpfringe or mpcombine).
