HaruHostBy address
Copy the Server Address from the server's Details tab and send it to friends with the password. They join by that address the same way as any Arma Reforger dedicated server. This is the join on Windows, with the Tunnel or with Ports, and for a server on Ports on a VPS.
From the server list on Linux
When HaruHost runs as a service on Linux, as the one-command install sets it up, a tunneled server shows in Arma Reforger's server list at the Tunnel's public address. Friends search the Server Title from the Details tab and join it there. New servers are named HaruHost Arma Reforger and a number until you change it.
Without port forwarding
- Choose Add → New game server, pick the PC or server, then Arma Reforger. On the Steam Account step, pick or add the Steam account HaruHost downloads the server with.
- Choose Tunnel on the Connection step. For an existing server, turn the Tunnel on from its Details tab.
- Pick a region, or Closest region (automatic), and start the server.
The server gets a public address with no router setup, even behind CGNAT, Starlink or mobile internet. On Linux the Tunnel needs HaruHost running as a service, as the one-command install on Ubuntu sets it up. Regions are on the Tunnel page.
Can't connect?
- Check that the server shows as online in HaruHost.
- Copy the whole Server Address, with the port after the colon.
- In the server list, search the exact Server Title, not the Server Name, which is only HaruHost's label for the server.
- With Ports, the server's ports must be reachable from the internet. Or turn on the Tunnel.
Questions
Can I host Arma Reforger behind CGNAT?
Yes, with the Tunnel, on Windows or when HaruHost runs as a service on Linux. Players connect to the relay's address, so CGNAT and your router don't matter.
Where do I find the Server Title?
On the server's Details tab in HaruHost, above the Server Address. It is the name players see and search in the server list.
