L2Tp/Pptp Server - D-Link NetDefend SOHO DFL-160 User Manual

4.4.3. L2TP/PPTP Server

The Remote Network is the network behind the server to which the client will communicate.
B. Authentication
The client will need a username and password for authentication.
C. IPsec Encryption
L2TP usually uses IPsec as its encryption method.
D. Security Authentication
This section specifies how authentication is done when connecting to the server.
E. MPPE
Microsoft Point to Point Encryption (MPPE) is an optional encryption method usually used only by
PPTP. The method chosen must be compatible with the method chosen on the server.
F. Dial-on-Demand
If this option is enabled, the tunnel will not be set up until traffic is actually sent.
The Idle Timeout is the length of time with inactivity that passes before tunnel disconnection occurs.
4.4.3. L2TP/PPTP Server
This option allows VPN tunnels to be set up based on the L2TP protocol, where the DFL-160 acts as
a L2TP or PPTP server, receiving connection requests from external clients. Such clients are
sometimes called roaming clients since they might not have a fixed IP address and might connect
through temporary connection to a remote network.
Secure VPN connections by external clients could also be achieved, as described previously, using
IPsec tunnels. However, IPsec requires special IPsec client software be installed on the client
computer which can increase the overall complexity and expense of VPN. On many computers, such
as all Microsoft Windows PCs, L2TP and PPTP client software exists as a standard component
which means VPN is much simpler to implement.
The following sections appear in the web interface for setup:
A. General
B. IP Pool Settings
C. Authentication
D. MPPE
D. Idle Timeout
A. General
In this section of the page, the type of tunnel is selected (L2TP or PPTP) and if the tunnel uses IPsec
encryption (this is usually only the case for L2TP tunnels).
