This section describes how to configure the DFL-500 as an L2TP VPN server. This section also describes
how to configure Windows 2000 and Windows XP clients to connect to the L2TP VPN.
Configuring L2TP is similar to configuring PPTP. You must configure the DFL-500 to support L2TP by adding
L2TP users and specifying an L2TP address range. You can also require L2TP VPN users to authenticate to

for L2TP.
Make sure that your ISP supports L2TP connections.
