mtaserver.conf

The fields that matter at first:

<config>
    <servername>My RP Server</servername>
    <serverport>22030</serverport>   <!-- game port (UDP) -->
    <httpport>22031</httpport>       <!-- resource file downloads (TCP) -->
    <maxplayers>64</maxplayers>
    <resource src="spawn" startup="1" />
    <resource src="fivemobile_plataforma" startup="1" />
</config>

Each <resource ... startup="1"/> starts a resource when the server boots.

Ports

Open them in your firewall and router:

Port	Protocol	What for
22030	UDP	player connections
22031	TCP	resource file downloads

Test from your phone

With the server running, point the app at your PC's IP on the same Wi-Fi network and port 22030. If your player spawns and walks around, you're ready to start writing resources.

Next step

Read Resources and Lua scripts to build your first resource.
