Host a Dedicated Evrima Server

A static IP keeps your server's LAN address from changing every time the PC reboots. Without it, your port-forwarding rules go stale.

Evrima dedicated servers need ports open through your router and through Windows Firewall on the host PC.

SteamCMD is Valve's command-line client for downloading dedicated-server binaries. Grab it from the official Valve developer docs, extract it, and run steamcmd.exe once to let it auto-update.

Two files: Game.ini for everything you can tune (server name, mutations, allowed species, RCON, etc.) and Engine.ini for the EOS dedicated-server identity that lets the server start.

Path: C:\theisleserver\TheIsle\Saved\Config\WindowsServer\
If WindowsServerdoesn't exist, create it. Make sure file extensions are visible (File Explorer → … → Options → View → uncheck Hide extensions for known file types) so you save a real .ini and not Game.ini.txt.

Starter template — paste this into your empty Game.ini and tweak from there.

Required for the server to authenticate with Epic Online Services. Without these two lines the server won't start.

[EpicOnlineServices]
DedicatedServerClientId=<your-eos-dedicated-server-client-id>
DedicatedServerClientSecret=<your-eos-dedicated-server-client-secret>

Substitute the two values from your dedicated-server install — they ship as part of the standard Evrima server template and are the same across every host. If you don't have them yet, install the server first (Step 03) and look for the EOS block in the install's default config.

Two paths — pick whichever you'll actually use. The batch script is the production-grade option because it auto-updates and auto-restarts on crash.

?Port=7777 -log -ini:Engine:[EpicOnlineServices]:DedicatedServerClientId=<your-eos-dedicated-server-client-id> -ini:Engine:[EpicOnlineServices]:DedicatedServerClientSecret=<your-eos-dedicated-server-client-secret>

goto TheIsle

Launch the shortcut or batch and watch the log window. Once you see the server register successfully with EOS and start listening, it's live.

1. On a different machine (or your phone's mobile hotspot), launch The Isle, set the Session Filter to Unofficial, and search for your ServerName.
2. If it shows up — congrats, you're live. If it doesn't:
   • Confirm both the UDP and TCP firewall rules are allow inbound.
   • Confirm the router rule's destination IP matches your current static IP.
   • Check the server log window for EOS authentication errors — usually means Engine.iniisn't being read.
3. Try the Steam Game Servers route from your test machine as a second-look check.
