About VPN
A VPN provides a secure communication channel (“tunnel”) between two gateway
routers or between a remote PC and a gateway router. The security appliance
provides the following VPN solutions:
• Cisco IPSec VPN Server: The Cisco IPSec VPN Server feature allows the
security appliance to act as a head-end device in remote access VPNs. The
server pushes the security policies to remote clients, so that remote clients
have up-to-date policies in place before establishing the connections. The
server can also terminate the VPN tunnels initiated by the clients. This
flexibility allows mobile and remote users to access critical data and
applications on corporate Intranet. See Configuring the Cisco IPSec VPN
Server, page 233.
