Custom Public Ports

Choose your own public port for an exposed service.

Syntax

Add the exact public port after the local port. Use the transport command that matches your service:

exposr tcp <local-port> <public-port>
    exposr udp <local-port> <public-port>

Examples

# Expose local port 3000 on public port 21342
exposr tcp 3000 21342

# Expose local port 8080 on public port 25000
exposr tcp 8080 25000

# Expose Minecraft on its default port
exposr tcp 25565 25565

Considerations

• The requested public port must be available on the server
• The port must be allowed through the server's firewall
• When specifying a custom port, Exposr does not fall back to a random port if it's unavailable
