Configuring Ipsec Remote-Access Tunnel Group Ppp Attributes - Cisco FirePOWER ASA 5500 series Configuration Manual

Configuring Tunnel Groups
For example, the following commands enable hybrid XAUTH on the inside interface for a tunnel group
called example-group:
hostname(config)# tunnel-group example-group type ipsec-ra
hostname(config)# tunnel-group example-group ipsec-attributes
hostname(config-tunnel-ipsec)# isakmp ikev1-user-authentication (inside) hybrid
hostname(config-tunnel-ipsec)#

Configuring IPSec Remote-Access Tunnel Group PPP Attributes

To configure the Point-to-Point Protocol attributes for a remote-access tunnel group, do the following
steps. PPP attributes apply only to IPSec remote-access tunnel groups. The following description
assumes that you have already created the IPSec remote-access tunnel group.
Enter tunnel-group ppp-attributes configuration mode, in which you configure the remote-access
Step 1
tunnel-group PPP attributes, by entering the following command. The prompt changes to indicate the
mode change:
hostname(config)# tunnel-group tunnel-group-name type ipsec-ra
hostname(config)# tunnel-group tunnel-group-name ppp-attributes
hostname(config-tunnel-ppp)#
For example, the following command designates that the tunnel-group ppp-attributes mode commands
that follow pertain to the tunnel group named TG1. Notice that the prompt changes to indicate that you
are now in tunnel-group ppp-attributes mode:
hostname(config)# tunnel-group TG1 type ipsec-ra
hostname(config)# tunnel-group TG1 ppp-attributes
hostname(config-tunnel-ppp)#
Specify whether to enable authentication using specific protocols for the PPP connection. The protocol

value can be:

•
CHAP and MSCHAPv1 are enabled by default.
The syntax of this command is:
hostname(config-tunnel-ppp)# authentication protocol
hostname(config-tunnel-ppp)#
To disable authentication for a specific protocol, use the no form of the command:
hostname(config-tunnel-ppp)# no authentication protocol
hostname(config-tunnel-ppp)#
For example, the following command enables the use of the PAP protocol for a PPP connection.
hostname(config-tunnel-ppp)# authentication pap
hostname(config-tunnel-ppp)#
The following command enables the use of the MS-CHAP, version 2 protocol for a PPP connection:
