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 Point-to-Point Tunneling Protocol (PPTP) and Layer Two
Tunneling Protocol (L2TP) 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 Global settings page, you can enable or disable the Gateway’s VPN settings.
