Environment Variables

The following environment variables are required to run the program:

• UDP_LISTEN_PORT: The port on which the server will listen for incoming UDP packets.
• UDP_DESTINATIONS: A comma-separated list of destination addresses (IP:port) to forward packets to.
• LOG_LEVEL: (Optional) The logging level. Defaults to "info" if not set. Options are: trace, debug, info, warn, error, fatal, panic.

Example:

export UDP_LISTEN_PORT=5000
export UDP_DESTINATIONS=10.0.0.1:6000,10.0.0.2:6000
export LOG_LEVEL=debug
