Dedicated Server Guide

This document is set up to help survivors configure a Windows ZSGO Dedicated server. It is recommended that you have a dedicated machine with a good CPU and it is advised not to use your home machine. Please note that there are several port firewall steps (yar have been warned!).

Download the Dedicated Server Tool from Steam

Download the ZSGO Dedicated Server Tool on Steam

Once purchasing ZSGO on Steam, you will automatically have access to downloading the ZSGO Dedicated Server tool. All you have to do is hit the drop down at the top right of your Steam client and check off "Tools".

Then, find the ZSGO Dedicated Server and Install.

Configuring the ZSGOServer.exe

Do not Launch; create a shortcut. You must create a shortcut and add -server -log to the end of the target.

1. In Steam: Right-click Properties -> Installed Files -> Browse -> Right-click ZSGOServer.exe and create a shortcut.
2. Then, right-click the shortcut go to properties, and add -server -log to the end of the target line.
3. Changing the port If desired (or needed), change the port and query port using the following launch parameters: -port=[PORT] -queryport=[PORT]. The Port and Steam Query port must be different (the default game port is 26900 and the default Steam query port is 27015).
4. Running Multiple Servers on Same Machine If you are running multiple servers on the same machine, you can tie them to specific IP addresses (preferably static) by using -multihome=[IP ADDR]. (Port changes are required if running multiple servers on the same machine).
5. Close / Exit out of steam.
6. Run the shortcut as admin.

Adding Ports to the Firewall

Ensure that your server has ports 26900 & 27015 TCP/UDP, both inbound and outbound (and/or any additional ports specified by you, using the port and query port launch parameters).

Add Inbound ICMP V4 (ping).

Changing the Dedicated Server Settings

Navigate to: [Steam install directory]\steamapps\common\ZSGO Dedicated Server\ZSGO\Content\DedicatedServer\ServerConfig.json

MaxPlayers: Default 4. Can go up to 32 (we recommend a maximum of 20, however you can go higher. Do so at your own risk!).
