- 8-16 GB
- Default server ports
- 2001 (game), 17777 (query)
- Protocol
- UDP
- Server OS

You never forward any of these. The agent connects outward to our relay; the game's ports stay on your machine.
Bohemia allows community servers under their published server rules; monetizing a server needs their separate approval program.
Why host Arma Reforger with Multiplayer Rally
The 2025 surge made Reforger the new home for milsim communities, and those communities host heavily. The server files are free on SteamCMD and Bohemia publishes the hosting rules.
- Heavy server: Arma Reforger is one of the bigger ones, around 8-16 GB. You'll want a PC with that much RAM to spare on top of everything else.
- Arma Reforger uses several server ports, the classic spot people get stuck setting up by hand. We set every one of them for you.
- Runs the official Arma Reforger server on Windows, Linux. We download it from the publisher and keep the runtime patched.
- Your Arma Reforger world stays set up between sessions. The app handles restarts, updates, and the relay link so the squad can drop in whenever you're online.
How hosting Arma Reforger works
- Step 01
Install Multiplayer Rally
One Windows app. It installs and manages the Arma Reforger dedicated server for you. No command line, no config files.
- Step 02
Pick Arma Reforger
We set the ports, the settings, and the restart schedule. You pick the world name and who's allowed in.
- Step 03
Share your link
You get one address your friends paste into the game, and they're in. Nothing to install on their side, no port forwarding on yours.
Arma Reforger hosting questions
Plan on 8-16 GB of free RAM for a friend-group server. Your PC needs that on top of whatever else it's running; the app checks before installing.
2001 (game), 17777 (query) (UDP). With Multiplayer Rally you don't forward any of them: the agent makes an outbound connection to our relay, and your friends connect to the relay address.
Yes, that's the whole point. The agent on your PC makes an outbound connection to our relay, so you never touch your router. Your friends connect to the relay address and the traffic is tunneled to your Arma Reforger server. Nothing is exposed to the open internet.
Yes. Each player needs their own copy of Arma Reforger to join your server. We host the server side; the game itself comes from the store like always.
Arma Reforger is in our planned launch catalog. Join the waitlist, pick Arma Reforger as your game, and we'll email you when it's live.
Your PC is the server, so the world is offline until you turn it back on, then it's right where you left it. The agent restarts Arma Reforger for you automatically. An always-on managed tier on our hardware comes later.
