134 Chapter 4: Configuring Cisco VPN 3000 for Remote Access Using Preshared Keys
VPN Concentrator Configuration
Three major categories of activities that should be performed on network devices are
configuration, administration, and monitoring. The browser-based VPN 3000 Concentrator
Series Manager was designed with those functions in mind. The remainder of this chapter
focuses on the configuration capabilities of the VPN concentrator.
Remote access VPNs can be established with minimal equipment. Most of your users connect
through the Internet, so their infrastructure costs are minimal. While you should place the
concentrator behind or in parallel with a firewall, you could establish a robust VPN network
with just a border router and your concentrator.
Administration requirements for the Cisco VPN 3000 Concentrator Series are fairly standard. You
could configure the concentrators completely from the CLI using either a directly connected
console monitor or by Telnetting to the concentrator. However, the best option for configuring this
series of concentrators is through the GUI that you access through a web browser.
Microsoft Internet Explorer version 4.0 or higher is the recommended browser to use, but you
can also use Netscape Navigator/Communicator version 4.0 or higher. You must enable the
use of JavaScript and cookies in the browser application in order for the Cisco VPN 3000
Concentrator Manager to work properly. Nothing needs to be installed on your workstation
other than the browser software.
