Start your Arma 3 server

One Arma 3 dedicated server allows you to host multiplayer military, co-op or life RP missions for your community. This guide explains how to start from the Anthony IT Solutions panel, UDP ports, address recovery and first checks before hosting your players.

Arma 3 uses Steam Query and BattlEye for anti-heat. The server must have a valid Steam license (included in the offer).
