If your Windows 2000 or Windows XP VPN clients are either making L2TP/IPSec connections or using certificates for user-level authentication to various corporate resources, you must install certificates on the VPN client computer. For L2TP/IPSec connections, you must install a computer certificate on the VPN client computer to provide authentication for establishing an IPSec security association (SA). For userlevel authentication using the Extensible Authentication Protocol-Transport Layer

Security (EAP-TLS) authentication protocol, you can use either a user certificate or a smart card. You can use another method for L2TP/IPSec authentication known as a preshared key, which can be used in place of certificates if certificate services are not available, but this method is only minimally supported by Microsoft operating systems because of security issues inherent with preshared keys. Microsoft recom mends the use of certificates for all IPSec-enabled communications including L2TP/IPSec. For user certificate-based authentication, if a company has not deployed the Microsoft Active Directory directory service, the computer user must request a user certificate from a Windows Server 2003 certificate authority (CA) on the company intranet. If the company has a deployment of Active Directory on Windows Server 2003, users can be automatically configured with certificates upon logon to the sys tem by using the new auto-enrollment CA features of Windows Server 2003. For smart card based authentication, a network administrator must configure an enroll ment station and issue smart cards with certificates that are mapped to individual user accounts. The use of smart cards is an excellent idea if you want to have twofactor authentication for all users. By using two-factor authentication, you can maintain security much more easily because a hacker cannot break in if he discov ers one of the factors. The hacker would need to have the smart card and the per sonal identification number (PIN) to activate the smart card. Only the actual user in physical possession of the smart card can provide both of those items. For more information about installing certificates on VPN client computers, see the Certificate Infrastructure section in this chapter.

versions of Microsoft operating systems, use the CM components of Win dows Server 2003 to create the custom VPN connection profile for distribu tion and to maintain the phone-book database for your POPs. Doing this will allow you to maintain the clients with CMAK rather than maintaining support for each individual operating system that is being used. The same CM profiles will operate across all supported operating systems.

for a Certificate Services installation and, if possible, use Active Directory on Windows Server 2003 to take advantage of the auto-enrollment CA feature.
If you are using Windows XP or Windows 2000 VPN clients and user-level
certificate authentication with EAP-TLS, you must install either a user certifi cate on the VPN client computer or a user certificate on the smart card used by the VPN client computer. Again, if possible, use Active Directory on Win dows Server 2003 the proper certificate will be installed for each user when they log on.
Internet Network Infrastructure
In all our discussions of remote access solutions for VPN, we will be working with connections over the Internet. This means we are reliant on the Internet, which is the intermediate network, to provide certain services and transports to the users. You need to check several items to make sure the Internet communications system will be able to connect your users to your VPN server. To create a VPN connection to a VPN server across the Internet, you need to verify the following items first before any connections can be created:
