Configuring VPN Settings
A Virtual Private Network (VPN) is a technology designed to increase the security of
information transferred over the Internet. A VPN creates a private encrypted tunnel from the
user's computer, through the local wireless network, through the Internet, all the way to the
corporate servers and database.
The Gateway supports the Internet Protocol Security (IPSec) to secure IP traffic. IPSec
builds “virtual tunnels” between a local and remote subnet for secure communication
between two networks. This connection is commonly known as a Virtual Private Network
(VPN).
Alternatively, tunneling protocols such as L2TP and PPTP can be used to achieve a secure
connection (such as to a corporate LAN) over the Internet. These tunneling protocols can
optionally be secured themselves using IPSec.
Using the VPN menu, you can enable or disable the Gateway’s VPN settings. If the VPN
settings are enabled, you can use VPN submenus to:
y
Allow PC clients behind the Gateway to access the IPSec VPN tunnel. See page 147.
y
Define the VPN tunnel configuration. See page 148.
Using the VPN Menu
You can use the VPN menu to enable or disable the Gateway’s VPN functions. By default,
the Gateway’s Virtual Private Network (VPN) settings are disabled.
To access the VPN menu, click
VPN
in the menu bar. Figure 83 shows an example of the
menu and Table 33 describes the options you can select.
