Complete LNS and L2TP Client Configuration Example
The following provides a configuration example of an LNS and L2TP Client.
Assumptions
IP Addresses
The LNS server’s LAN IP address is 192.168.100.1 (
LNSserver
) with a mask of 255.255.255.0.
The LNS has a WAN IP address of 192.168.110.1, which is used as the tunnel endpoint.
The LNS connects to the remote
internet
.
The L2TP Client’s LAN IP address is 192.168.101.1 (
soho
) with a mask of 255.255.255.0. Additionally,
192.168.101.1 is also the tunnel endpoint within the L2TP client. The router
soho
connects to the remote
isp
.
Secret/password
A shared tunnel secret of “tunnelsecret” will be used.
PPP Authentication
The LNS will authenticate the client using PPP. The client will not try to authenticate the LNS using
PPP. For PPP authentication, the L2TP client will be known as “lacclient” with a password of
“clientpassword”.
Tunnel
Only the L2TP client (
soho
) will initiate the tunnel and make the connection. The tunnel is routed
through the remote
internet
which is the default route. The LNS server never calls the L2TP client
(
soho
).
