Hi,On all recent RADIUS

Hi,

On all recent RADIUS server implementations, UDP/1812 is the authentication and authorization port, and UDP/1813 is the accouting port. However, in historic RADIUS versions, these ports were different: UDP/1645 for autentication and authorization, and UDP/1646 for accounting.

Best regards,
Peter
