MAX 6000/3000 Network Configuration Guide

 11-39

For the purposes of this example, a MAX authenticates the initial PPP dial-in by its dialed 
number. (DNIS authentication is not required for tunnel authentication.) Another MAX 
operates as an L2TP Network Server (LNS).

The following settings configure a Connection profile for the PPP client and specify a Client 
ID name:

Ethernet

Connections

Tunnel options... 

Profile type=Mobile-client

Tunnel protocol=L2TP

Tunnel-Type (64)

Tunneling protocol(s) to be used. Must be set to L2TP (3) or L2F 
(2) to use this feature. 

Tunnel-Server-Endpoint 
(67)

IP address or hostname of the tunnel end point. If a DNS lookup   
returns several IP addresses, the system attempts to establish a 
tunnel to each address in turn.

Tunnel-Password (69)

Shared secret for authenticating the tunnel. 

Tunnel-Client-Auth-ID 
(90)

Name sent to the tunnel end point by the system requesting the 
tunnel (the NAS or LAC) during the tunnel authentication phase. 
The name can contain up to 31 characters. See “How the system 
name is selected” on page 11-42.

Tunnel-Server-Auth-ID 
(91)

Name sent from the tunnel end point (the gateway or LNS) to the 
system initiating the tunnel during the tunnel authentication phase. 
The name can contain up to 31 characters.

Tunnel-Server-Auth-ID (91) does not apply unless the protocol 
used to establish the tunnel is L2TP or L2F. The attribute can be 
specified in access-response packets and is generated in 
accounting-request packets.
