Understanding the VPN Client

The Cisco VPN Client for Mac OS X is a software application that runs on any Macintosh computer using operating system Version 10.2 or later. The VPN Client on a remote PC, communicating with a Cisco VPN device on an enterprise network or with a service provider, creates a secure connection over the Internet. This connection allows you to access a private network as if you were an on-site user, creating a Virtual Private Network (VPN).

The following VPN devices can terminate VPN connections from VPN Clients:

• Cisco IOS devices that support Easy VPN server functionality

• VPN 3000 Series Concentrators

• Cisco PIX Firewall Series, Version 6.2 or later

With the graphical user interface for the VPN Client for Mac OS X, you can establish a VPN connection to a private network; manage connection entries, certificates, events logging; and view tunnel routing data.

You can also manage the VPN Client for Mac OS X using the command-line interface (CLI). If you are running Darwin, or if you prefer to manage the VPN Client from the CLI, refer to the Cisco VPN Client Administration Guide.

Connection Technologies

The VPN Client lets you use any of the following technologies to connect to the Internet:

• POTS (Plain Old Telephone Service)—Uses a dial-up modem to connect.

• ISDN (Integrated Services Digital Network)—May use a dial-up modem to connect.

• Cable—Uses a cable modem; always connected.

• DSL (Digital Subscriber Line)—Uses a DSL modem; always connected.

You can also use the VPN Client on a PC with a direct LAN connection.

OL-5490-01

VPN Client User Guide for Mac OS X

VPN Client Overview

The VPN Client works with a Cisco VPN device to create a secure connection, called a tunnel, between your computer and a private network. It uses Internet Key Exchange (IKE) and Internet Protocol Security (IPSec) tunneling protocols to establish and manage the secure connection.

The steps used to establish a VPN connection can include:

• Negotiating tunnel parameters (addresses, algorithms, lifetime)

• Establishing VPN tunnels according to the parameters

• Authenticating users (from usernames, group names and passwords, and X.509 digital certificates.)

• Establishing user access rights (hours of access, connection time, allowed destinations, allowed

protocols)

• Managing security keys for encryption and decryption

• Authenticating, encrypting, and decrypting data through the tunnel

For example, to use a remote PC to read e-mail at your organization, the connection process might be similar to the following:

Chapter 1 Understanding the VPN Client

Step 1 Connect to the Internet.

Step 2 Start the VPN Client.

Step 3 Establish a secure connection through the Internet to your organization’s private network.

Step 4 When you open your e-mail

• The Cisco VPN device

–

Uses IPSec to encrypt the e-mail message

–

Transmits the message through the tunnel to your VPN Client

• The VPN Client

–

Decrypts the message so you can read it on your remote PC

–

Uses IPSec to process and return the message to the private network through the Cisco VPN device.

IPSec Feature Description

Split tunneling The ability to simultaneously direct packets over the Internet in

clear text and encrypted through an IPSec tunnel. The VPN device supplies a list of networks to the VPN Client for tunneled traffic. You enable split tunneling on the VPN Client and configure the network list on the VPN device.

Support for Split DNS The ability to direct DNS packets in clear text over the Internet to

domains served through an external DNS (serving your ISP) or through an IPSec tunnel to domains served by the corporate DNS. The VPN server supplies a list of domains to the VPN Client for tunneling packets to destinations in the private network. For example, a query for a packet destined for corporate.com would go through the tunnel to the DNS that serves the private network, while a query for a packet destined for myfavoritesearch.com would be handled by the ISP's DNS. This feature is configured on the VPN server (VPN Concentrator) and enabled on the VPN Client by default. To use Split DNS, you must also have split tunneling configured.

Figure 2-2 VPN Client Installer Directory

Preconfiguring the User Profile

Preconfiguring the VPN Client

The VPN Client uses parameters that must be uniquely configured for each remote user of the private network. Together these parameters make up a user profile, which is contained in a profile configuration file (.pcf file).

To distribute preconfigured profiles, copy the configuration files (.pcf files) into the Profiles folder in the vpnclient installer directory.

Any file with a .pcf extension found in this folder is placed in the Profiles directory when the VPN Client is installed.

Preconfiguring the Global Profile

A global profile sets rules for all remote users; it contains parameters for the VPN Client as a whole. The name of the global profile file is vpnclient.ini.

The vpnclient.ini file controls the following features:

• Control of logging services by class

• Certificate enrollment

• Missing group warning message

• VPN Client GUI preferences, such as window locations and sizes

If you do not preconfigure a global profile, the vpnclient.ini file is populated with default settings. Each time you make changes, the vpnclient.ini file is updated and stored.
