L2Tp Vpn Configuration; Configuring The Dfl-500 As An L2Tp Gateway - D-Link DFL-500 User Manual

No special VPN configuration is required. When the PPTP client connects to the destination PPTP VPN
gateway, the DFL-500 accepts PPTP packets from the internal network. The DFL-500 performs network
address translation to change the source address of these packets to the IP address of the external
interface of the DFL-500. The DFL-500 then forwards the PPTP packets to the PPTP VPN gateway.

L2TP VPN configuration

Configuring L2TP is similar to configuring PPTP. You 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 your
RADIUS server. Finally, to connect to the L2TP VPN, your remote Windows clients must be configured for
L2TP.
Make sure that your ISP supports L2TP connections.
