Configuring VPDN Group Authentication
Your ISP may require you to use authentication with PPPoE. The Security Appliance PPPoE
Client supports the following authentication protocols:
¦ Password Authentication Protocol (PAP)
¦ Challenge Handshake Authentication Protocol (CHAP)
¦ Microsoft Challenge Handshake Authentication Protocol (MS-CHAP)
To define the authentication protocol for the PPPoE client, you use the following command:
vpdn group group-name ppp authentication pap | chap | mschap
Assigning the VPDN Group Username
To assign the username provided by your ISP to the VPDN group, you use the following
command:
vpdn group group-name localname username
Configuring the VPDN Username and Password
The Security Appliance uses a username and password pair to authenticate to the AC. To
assign a username and password pair for PPPoE authentication, you use the following
command:
vpdn username username password password
NOTE ISPs that use CHAP or MS-CHAP may refer to the username as the remote system
name and the password as the CHAP secret.
