Select the 6. Authentication Type to be applied to the dial-in connection.
The ECS0016 uses authentication to challenge Administrators who •
dial-in to the gateway. (For dial-in access, the username and
pass word received from the dial-in client are verified against the
local authentication database stored on the ECS0016). The
Administrator must also have their client PC / workstation configured
to use the selected authentication scheme.
Select 7. PAP, CHAP, MSCHAPv2 or None and click Apply.
None• - With this selection, no username or password authentication
is required for dial-in access. This is not recommended.
PAP - • Password Authentication Protocol (PAP) is the usual method
of user authentication used on the internet: sending a username and
password to a server where they are compared with a table of
authorized users. Whilst most common, PAP is the least secure of
the authentication options.
CHAP -• Challenge Handshake Authentication Protocol (CHAP) is
used to verify a user’s name and password for PPP Internet
connections. It is more secure than PAP, the other main
authentication protocol.
MSCHAPv2• - Microsoft Challenge Handshake Authentication
Protocol (MSCHAP) is authentication for PPP connections between
a computer using a Microsoft Windows operating system and a
network access server. It is more secure than PAP or CHAP, and is
the only option that also supports data encryption
