9.5.4. PPTP/L2TP Clients
•
Idle Timeout - The time of inactivity in seconds to wait before disconnection.
Using the PPTP Client Feature
One usage of the PPTP client feature is shown in the scenario depicted below.
Here a number of clients are being NATed through NetDefendOS before being connected to a PPTP
server on the other side of the D-Link Firewall. If more that one of the clients is acting as a PPTP
client which is trying to connect to the PPTP server then this will not work because of the NATing.
The only way of achieving multiple PPTP clients being NATed like this, is for the D-Link Firewall
to act as a PPTP client when it connects to the PPTP server. To summarize the setup:
•
A PPTP tunnel is defined between NetDefendOS and the server.
•
A route is added to the routing table in NetDefendOS which specifies that traffic for the server
should be routed through the PPTP tunnel.
