For an interface with Point-to-Point Protocol (PPP) encapsulation, you must configure a PPP access profile and bind it to an interface. You create an access profile with a user-defined name that is unique on the security device. You can bind the same access profile to more than one interface, but only one profile can be assigned to an interface.
You can configure a specific instance of Point-to-Point Protocol over ATM (PPPoA) with a username and password and other parameters, and bind the instance to an interface.
Enter the necessary information:
PPP Profile: Enter the name of the profile. Choose a descriptive name to help you identify the profile.
Authentication: Select the authentication method.
CHAP means only Challenge Handshake Authentication Protocol (CHAP) authentication is used.
PAP means only Password Authentication Protocol (PAP) authentication is used.
You can select one or both authentication options. There will be no authentication if neither option is selected.
Static IP: Specifies that the connection uses the IP address assigned to the device's interface.
Netmask: Enter the netmask for the PPP profile.
Passive: Selecting this check box configures the device to not challenge the peer.
Local Name: Enter the username for the PPP profile.
Password: Enter the password for the PPP profile.
NCP: Select the Network Control Protocol (NCP) to be used. You can configure PPP to negotiate with Internet Protocol Control Protocol (IPCP), Internet Protocol version 6 Control Protocol (IPv6CP), or both.
Try IPCP Only: Select this option to enable PPP to negotiate with an IPCP session. This option is selected by default.
Try IPv6CP Only: Select this option to enable PPP to negotiate with an IPv6CP session.
Try IPCP first, then IPv6CP: Select this option to enable PPP to negotiate first with an IPCP session, then with an IPv6CP session.
Try IPv6CP first, then IPCP: Select this option to enable PPP to negotiate first with an IPv6CP session then with an IPCP session.
