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.

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.

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

MSCHAPv2
