listen

The listen attribute is used to configure the network interfaces and ports on which the RADIUS server will accept requests. This is used to define specific IP addresses and ports for handling RADIUS traffic.

Example configuration of a listen clause:

listen {
    # Transport protocol
    protocol udp;

    # Transport protocol port to listen to
    port 1813;

    # IPv4 address to listen to
    ip 127.0.0.1;
}
