To list all of the features would take about a dozen or so pages therefore, I'll briefly cover some of the VPN Client's more important features in Table 12-1. For IPsec, it supports both main and aggressive modes for ISAKMP/IKE Phase 1 MD5 and SHA-1 HMAC functions pre-shared keys, mutual group authentication, digital certificates, and XAUTH user authentication DH group 1, 2, and 5 keys and DES, 3DES, AES-128, and AES-256 (AES is new in version 3.6) encryption. There are many, many features that the VPN Client provides some are based on open standards and some are proprietary to Cisco. Because the software implements client features, the VPN Client can have only one session active at a time. It can be used to establish a secure IPsec session using either a dialup connection via PPP, a wireless connection, or even a LAN-based connection, such as Ethernet. The Cisco VPN Client for Windows (Version 4.6) supports Windows 98, Windows NT 4.0, Windows ME, Windows 2000, and Windows XP platforms. Also, Cisco used to offer two other clients, but these have been discontinued: the Cisco Secure VPN Client (discontinued in 2003) and the Cisco VPN 5000 Client (discontinued in 2002). Because of space constraints, I will not be covering the non-Windows versions of the client. Therefore, this book will focus on using the 4.6 Windows client and I'll point out differences between the 3.x and 4.x clients as I proceed through the chapter. The GUI interfaces between the two are different however, how you perform tasks within each client is very similar. There are two basic versions of the Cisco software client for Windows: Versions 3.x and 4.x. The following sections will discuss the features and installation of the VPN Client for Microsoft Windows. Other VPN connection methods, such as PPTP, L2TP/IPsec, and WebVPN, are not supported with Cisco VPN Client software. Supported servers include the VPN 3000 series concentrators, IOS-based routers, and PIX and ASA security appliances. The Cisco VPN Client uses IPsec to establish a remote access VPN session to an Easy VPN Server using Cisco Easy VPN technology. Of the four, the Microsoft and Macintosh clients support a graphical user interface (GUI) the other two use a command-line interface (CLI). The Cisco VPN Client is a VPN remote access client that runs on Microsoft Windows PCs, Linux PCs (Intel-based), Macintoshes (Mac OS X), and Sun UltraSPARC workstations (Solaris).
