                                    | IP Address/Hostname  | IP address or hostname of your Radius server. | 
                                
                                    |  Type of RADIUS Authentication | Select an authentication protocol.  
                                            
                                                PAP (Password Authentication Protocol)
                                                CHAP (Challenge Handshake Authentication
                                                  Protocol) Note - 
                                                  CHAP is generally considered more secure
                                                  because the user name and password are encrypted,
                                                  while in PAP they are transmitted in the
                                                  clear.
                                                
                                                MS-CHAPv2 (Microsoft Challenge Handshake
                                                  Authentication Protocol) Note - 
                                                   MS‑CHAPv2 provides stronger security than
                                                  the above two. Selecting this option supports both
                                                  MS-CHAPv1 and MS-CHAPv2.

                                            with the Radius server before timing out. Type the timeout period in seconds. |
