Chapter 4. VPN Configuration
If you require more than an ordinary, unencrypted connection to the
Internet, the router supports IPSec to allow secure communications
from a network to another network, or from a client to a network.
The Virtual Private Network (VPN) protects your data by encrypting
it while it is sent across the Internet. Additionally, it assures that the
traffic you are receiving is actually from the computer you are ex-
pecting to exchange traffic with. Up to eight (8) tunnels may be con-
figured on the router.
There are two modes for setting up a VPN using the router: net-
work-to-network and client-to-network. From the Setup Wizard
screen, click on the VPN Settings button to configure your VPN.
Enter a connection name for the tunnel and click ADD. The tunnel is
automatically enabled when you add the name.
4.1 Network-to-Network
In a network-to-network VPN, the VPN joins the network on the LAN
side of the router with another network (which may be the LAN side
of another router). In between the two is a connection that may not
be trusted (the public Internet). The VPN allows traffic to “tunnel”
securely through the network cloud.
