Cable/DSL VPN Router with 4-Port 10/100 Switch
Virtual Private Networking (VPN) is a security measure that basically creates
a secure connection between two remote locations. This connection is very
specific as far as its settings are concerned; this is what creates the security.
The VPN screen, shown in Figure 6-8, allows you to configure your VPN set-
tings to make your network more secure.

Note: Network security, while a desirable and often necessary
aspect of networking, is complex and requires a thorough under-
standing of networking principles.

Connect on Demand and Max Idle Time You can configure the Router to cut
your connection with your ISP after a specified period of time (Max Idle
Time). If you have been disconnected due to inactivity, Connect on Demand
enables the Router to automatically re-establish your connection as soon as you
attempt to access the Internet again. If you wish to activate Connect on
Demand, click the radio button. If you want your Internet connection to remain
on at all times, enter 0 in the Max Idle Time field. Otherwise, enter the num-
ber of minutes you want to have elapsed before your Internet access discon-
nects.
Keep Alive Option and Redial Period This option keeps your PPPoE-enabled
Internet access connected indefinitely, even when it sits idle. Click the radio
button next to Keep Alive to select it. The default Redial Period is 30 seconds.
