CHAPTER

Configuration
Configuring the VPN Concentrator means setting all the parameters that govern its use and functionality
as a VPN device.
Cisco supplies default parameters that cover typical installations and uses; and once you supply minimal
parameters in Quick Configuration, the system is operational. But to tailor the system to your needs, and
to provide an appropriate level of system security, you should configure the system in detail.

Configuration

This section of the Manager lets you configure all VPN Conce ntrator features and functions.
•Interfaces: parameters specific to the Ethernet interfaces: public, private, and external; WAN
interfaces: ports A and B; plus power supply and voltage sensor alarms.
•System: parameters for system-wide functions: server access, address assignment, tunneling protocols,
IP routing, built-in management servers, system events, and system identification.
•User Management: attributes for groups and users that determine their access to and use of the VPN.
•Policy Management: policies that control data traffic through the VPN via filters, rules, and IPSec
Security Associations; network lists; access times; and NAT.
