In the
Remote Address
field, enter the IP address to be assigned to the dial-‐in client. You can
select any address for the Remote IP Address. It, and the Local IP Address, must both be in the
same network range (
e.g.
200.100.1.12 and 200.100.1.67).
In the
Local Address
field, enter the IP address for the Dial-‐In PPP Server. This is the IP address
that will be used by the remote client to access
console server
once the modem connection is
established. You can select any address for the Local IP Address but it must be in the same
network range as the Remote IP Address.
The
Default Route
option enables the
dialed PPP connection to become the default route for
the
Console server
.
The
Custom Modem Initialization
option allows you to enter a custom AT string modem
initialization string (
for example,
AT&C1&D3&K3).
You must select the
Authentication Type
to apply to the dial-‐in connection. The
console server
uses authentication to challenge
Administrators
who dial-‐in to the
console server
. (For dial-‐in
access, the username and password received from the dial-‐in client are verified against the local
authentication database stored on the
console server
). The
Administrator
must also configure
the client PC/workstation to use the selected authentication scheme. Select
PAP, CHAP,
MSCHAPv2,
or
None,
and click
Apply.
None
With this selection, no username or password authentication is required for
dial-‐in access. We do not recommend this.
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. While 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.
