connect

This clause defines the connection parameters for the RADIUS backend server, specifying how Radiator establishes a connection to a server that is specified with specific parameters. These parameters include the transport protocol, either the IP address or the hostname, and the port number. This clause is not mandatory. It is used when RADIUS messages need to be forwarded to another RADIUS server. This is common in roaming scenarios, where authentication requests from local users are handled locally, while requests from roaming partners are forwarded to a remote RADIUS server.

Example configuration of a connect clause:

connect {
    # transport protocol: udp/tcp/tls
    protocol udp;

    # server's IP address
    ip 203.0.113.111;

    # alternatively server's hostname
    #hostname radius1.example.org;

    # destination UDP port
    port 1812;

    # Optional: receive and send buffer size in bytes
    #buffer 1048576;
} # connect
