This chapter introduces the basics of IPSec VPNs and covers the VPN WebGUI.

VPN

A VPN (Virtual Private Network) provides secure communications between sites

without the expense of leased site-to-site lines. A secure VPN is a combination of

tunneling, encryption, authentication, access control, and auditing technologies or

services used to transport traffic over the Internet or any insecure network that

uses the TCP/IP protocol suite for communication.

Use the screens documented in this chapter to configure rules for VPN

connections and manage VPN connections.

IPSec

Internet Protocol Security (IPSec) is a standards based VPN that offers flexible

solutions for secure data communications across a public network like the

Internet. IPSec is built around a number of standardized cryptographic techniques

to provide confidentiality, data integrity and authentication at the IP layer.
