Preface

The VPN Concentrator provides an HTML-based graphic interface, called the VPN Concentrator Manager, that allows you to configure, administer, and monitor your device easily. The VPN Concentrator Manager has three sets of screens that correspond to these tasks: Configuration screens, Administration screens, and Monitoring screens.

VPN 3000 Series Concentrator Reference Volume I: Configuration is the first in the two volume VPN 3000 Series Concentrator Reference. Together, both volumes document all the screens of the VPN Concentrator Manager.

VPN 3000 Series Concentrator Reference Volume I: Configuration explains how to start and use the VPN Concentrator Manager. It details the Configuration screens and explains how to configure your device beyond the minimal parameters you set during quick configuration.
VPN 3000 Series Concentrator Reference Volume II: Administration and Monitoring provides guidelines for administering and monitoring the VPN Concentrator. It explains and defines all functions available in the Administration and Monitoring screens of the VPN Concentrator Manager. Appendixes to this manual provide troubleshooting guidance and explain how to access and use the alternate command-line interface.

This manual contains only configuration information. It contains no information about administering or monitoring the VPN Concentrator. For administration or monitoring information, refer to VPN 3000 Series Concentrator Reference Volume II: Administration and Monitoring.

This manual also contains no information about installing the VPN Concentrator and initially configuring it. For information about set-up and initial configuration, refer to the VPN 3000 Series Concentrator Getting Started.

Audience

We also assume you are an experienced system administrator or network administrator with appropriate education and training, who knows how to install, configure, and manage internetworking systems. However, virtual private networks and VPN devices might be new to you. You should be familiar with Windows system configuration and management, and you should be familiar with Microsoft Internet Explorer or Netscape Navigator or Communicator browsers.

Prerequisites

We assume you have read the VPN 3000 Series Concentrator Getting Started manual, set up your VPN Concentrator, and followed the minimal configuration steps in quick configuration.

Organization

The chapters and sections of this guide correspond to the Configuration part of the VPN Concentrator Manager table of contents (the left frame of the Manager browser window) and are in the same order they appear there.

This guide is organized as follows:

Chapter	Title	Explains How To...
Chapter 1	Using the VPN Concentrator Manager	Log in, navigate, and use the VPN Concentrator Manager with a browser. It explains both HTTP and HTTPS browser connections, and how to install the SSL certificate for a secure (HTTPS) connection.
Chapter 2	Configuration	Access the Configuration screens.
Chapter 3	Interfaces	Configure the VPN Concentrator Ethernet interfaces, and how to configure the system power supply and voltage sensor alarms.
Chapter 4	System Configuration	Access the System Configuration screens.
Chapter 5	Servers	Configure the VPN Concentrator to communicate with and access servers for user authentication, user accounting, converting host names to IP addresses (DNS), assigning client IP addresses (DHCP), and network time synchronization (NTP).
Chapter 6	Address Management	Configure the client IP addresses available in your private network addressing scheme to let the client function as a VPN tunnel endpoint.
Chapter 7	Tunneling Protocols	Configure system-wide parameters for PPTP and L2TP, how to configure IPSec LAN-to-LAN connections, and how to configure IKE proposals for IPSec. These are the three most popular VPN tunneling protocols.
Chapter 8	IP Routing	Configure static routes, default gateways, and OSPF in the VPN Concentrator IP routing subsystem; how to configure DHCP global parameters; and how to configure redundant systems using VRRP.
Chapter 9	Management Protocols	Configure built-in VPN Concentrator servers that provide management functions: FTP, HTTP and HTTPS, TFTP, Telnet, SNMP, and SSL.
Chapter 10	Events	Configure how the system handles events such as alarms, traps, error conditions, network problems, task completion, or status changes. You can specify several ways to record and send event messages.
Chapter 11	General	Configure the system identification, date, time, and maximum session limit.
Chapter 12	Client Update	Configure the VPN Concentrator to manage, from a central location, distribution of software and firmware updates to VPN 3002 hardware clients deployed in diverse locations.
Chapter 13	Load Balancing Cisco VPN Clients	Configure two or more VPN Concentrators to share their remote access session loads.
Chapter 14	User Management	Configure groups and users with attributes that determine their access to and use of the VPN. Configuring groups and users correctly is essential for managing the security of your VPN.
Chapter 15	Policy Management	Configure network lists, filters, rules, and Security Associations, all of which are policies that govern what data traffic can flow through the VPN. You should develop and configure policies first, since you apply them to groups, users, and interfaces. This chapter also describes NAT configuration.

Note This guide is the first volume of the complete VPN Concentrator Manager reference. It documents only configuration tasks. For information on administering or monitoring your VPN Concentrator, refer to the VPN 3000 Series Concentrator Reference Volume II: Administration and Monitoring.

Technical Assistance Center

The Cisco Technical Assistance Center (TAC) is available to all customers who need technical assistance with a Cisco product, technology, or solution. Two levels of support are available: the Cisco TAC Web Site and the Cisco TAC Escalation Center.

Cisco TAC inquiries are categorized according to the urgency of the issue:

Priority level 4 (P4)—You need information or assistance concerning Cisco product capabilities, product installation, or basic product configuration.
Priority level 3 (P3)—Your network performance is degraded. Network functionality is noticeably impaired, but most business operations continue.
Priority level 2 (P2)—Your production network is severely degraded, affecting significant aspects of business operations. No workaround is available.
Priority level 1 (P1)—Your production network is down, and a critical impact to business operations will occur if service is not restored quickly. No workaround is available.

The Cisco TAC resource that you choose is based on the priority of the problem and the conditions of service contracts, when applicable.

Cisco TAC Web Site

You can use the Cisco TAC Web Site to resolve P3 and P4 issues yourself, saving both cost and time. The site provides around-the-clock access to online tools, knowledge bases, and software. To access the Cisco TAC Web Site, go to this URL:

http://www.cisco.com/tac

All customers, partners, and resellers who have a valid Cisco service contract have complete access to the technical support resources on the Cisco TAC Web Site. The Cisco TAC Web Site requires a Cisco.com login ID and password. If you have a valid service contract but do not have a login ID or password, go to this URL to register:
