Description
Type of RADIUS
Authentication
Select an authentication protocol.
PAP (Password Authentication Protocol)
CHAP (Challenge Handshake Authentication Protocol)
MS-CHAPv2 (Microsoft Challenge Handshake Authentication
Protocol)
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 provides stronger security than the above two. Selecting
this option will support both MS-CHAPv1 and MS-CHAPv2.

Accounting Port
The defaults are standard ports -- 1812 and 1813.
