License, player connection & OneSync RedM

License, player connection & OneSync RedM

For a public RedM server to accept players, you must configure the Cfx.re license key, network settings, OneSync and possibly a whitelist. This guide covers Keymaster, ports, login address and visibility in the list of servers.

Cfx.re License Key (Keymaster)

1. Log in to keymaster.fivem.net with your Cfx.re account
2. Create a key for RedM (not FiveM)
3. Link the IP of your hosted server if requested
4. Copy the key to server.cfg : sv_licenseKey "votre_cle"
5. Restart the server

Ports & firewalls

• Main port: 30120 UDP/TCP (default)
• Port txAdmin if used: according to panel configuration
• At Anthony IT Solutions, game ports are opened automatically for your instance

Connection address

Format: IP:30120 or nom.custom.domain:30120 If you have a DNS reverse. Players can:

• Use F8 in RedM: connect IP:PORT
• Add server to favorites
• Go through a link redm://connect/IP:PORT on your website or Discord

OneSync

OneSync improves entity synchronization (players, horses, PNJ). In server.cfg :

• onesync on or onesync infinity according to slots and scripts
• Adjust sv_maxclients to your offer
• Some scripts require OneSync Infinity for >32 slots

Visibility list servers

• sv_hostname, attractive and unique name
• sets sv_projectName and sets sv_projectDesc
• sets tags, roleplay, western, francophone...
• Banner and icon via Asset Cfx.re if configured

Whitelist & Security

For a serious RP server, activate a whitelist (Discord bot, VORP script, or dedicated resource) before opening to the public. Limit direct connections during beta test.

Troubleshooting

• License key invalid, bad key or unregistered IP Keymaster
• Connecting failed, port, local client firewall, offline server
• Server full, increase slots or check offer

Logical suite: start RedM, resources.
