9.5.4. PPTP/L2TP Clients
The PPTP and L2TP protocols are described in the previous section. In addition to being able to act
as a PPTP or L2TP server, NetDefendOS also offers the ability to act as a PPTP or L2TP clients.
This can be useful if PPTP or L2TP is preferred as the VPN protocol instead of IPsec. One
NetDefend Firewall can act as a client and connect to another unit which acts as the server.
Client Setup
PPTP and L2TP shares a common approach to client setup which involves the following settings:
General Parameters
• Name - A symbolic name for the client.
• Interface Type - Specifies if it is a PPTP or L2TP client.
• Remote Endpoint - The IP address of the remote endpoint. Where this is specified as a URL,
the prefix dns: must be precede it.
