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.
