Configure the L2TP Server
As an alternate solution to IPSec VPN tunnels, you can configure a Layer 2 Tunneling
Protocol (L2TP) server on the VPN firewall to allow users to access L2TP clients over L2TP
tunnels. A maximum of 25 simultaneous L2TP user sessions are supported. (The very first IP
address of the L2TP address pool is used for distribution to the VPN firewall.)
An L2TP Access Concentrator (LAC) typi
cally initiates a tunnel to fulfill a connection request
from an L2TP user; the L2TP server accommodates the tunnel request. After an L2TP tunnel
is established, the L2TP user can connect to an L2TP client that is located behind the VPN
firewall.
IPSec VPN provides stronger authentication and encryption th
an L2TP. (Packets that
traverse the L2TP tunnel are not encapsulated by IPSec.)
You must enable the L2TP server on the VPN firewall, specify an
L2TP
server address pool,
and create L2TP user accounts. (L2TP users are authenticated through local authentication
