The following steps explain the Quick Mode process in detail: 1. Computer Red performs an IKE mode policy lookup to determine the full policy. (IKE negotiation does not factor in the port number, IP address, or other factors that might have triggered the negotiation.) 2. Computer Red proposes its options (cryptographic as well as frequency of key changes, and so on) and filters to Computer Blue. 3. Computer Blue does its own IKE mode policy lookup. If it finds a match with that proposed by Computer Red, it completes the Quick Mode negotiation to create a pair of IPSec SAs. 4. One SA is outbound, the other is inbound, each SA is identified by a Security Parameters Index (SPI), and the SPI is part of the header of each packet sent. Com puter Red s IPSec driver uses the outbound SA and signs, and, if specified, encrypts the packets. If hardware offload of IPSec cryptographic functions is supported by the network card, the IPSec driver just formats the packets; otherwise, it formats and cryptographically processes the packets. 5. The IPSec driver passes the packets to the network adapter driver. 6. The network adapter driver puts the datagrams on the network.

7. The network adapter at Computer Blue receives the (encrypted) packets from the network. 8. The SPI is used to find the corresponding SA. (This SA has the associated crypto graphic key necessary to decrypt and process the packets.) 9. If the network adapter is specifically designed to perform encryption and therefore can decrypt the packets, it will do so. It passes the packets to the IPSec driver. 10. Computer Blue s IPSec driver uses the inbound SA to retrieve the keys and pro cesses the packets if necessary. 11. The IPSec driver converts the packets back to normal IP packet format and passes them to the TCP/IP driver that passes them to the receiving application. 12. IPSec SAs continue processing packets. SAs are refreshed by IKE Quick Mode negotiation for as long as the application sends and receives data. When the SAs become idle, they are deleted. 13. IKE Main Mode is not deleted when idle. It has a lifetime of 8 hours, but this num ber is configurable (5 minutes to a maximum of 48 hours). New traffic triggers a new Quick Mode negotiation. If IKE Main Mode expires, a new IKE mode is nego tiated when needed.

1. In the console tree for Internet Authentication Service, right-click Remote Access Policies, and then click New Remote Access Policy. 2. On the Welcome To The New Remote Access Policy Wizard page, click Next. 3. On the Policy Configuration Method page, type Quarantined VPN remote access connections in the Policy Name text box, and click Next. 4. On the Access Method page, select VPN and click Next. 5. On the User Or Group Access page, select Group and click Add. 6. In the Select Groups dialog box, type VPNUsers in the Enter The Object Names To Select text box. Specify the location as example.com. Click OK. The VPNUsers group in the example.com domain is added to the list of groups on the User Or Group Access page. Click Next. 7. On the Authentication Methods page, the MS-CHAP v2 authentication proto col is selected by default. Click Next. 8. On the Policy Encryption Level page, clear the Basic Encryption and Strong Encryption check boxes and click Next. 9. On the Completing The New Remote Access Policy Wizard page, click Finish. 10. In the console tree for Internet Authentication Service, click Remote Access Policies, then in the details pane, right-click the Quarantined VPN Remote Access Connections policy, and click Properties.

This approach has the weakness of suggesting that the asterisk is part of the variable name, which it isn t. The variable can be used either with or without the asterisk. The best approach is to declare a type for the pointer and use that instead. An example is shown in Listing 31-55:

Note Switches and routers between Computer Red and Computer Blue will simply forward the encrypted packets to their destination. However, a firewall or packet filtering router must be configured to allow IPSec traffic to pass.

Creating an IPSec Policy is easy. Creating one that does exactly what you want it to is not always so easy. This far, you have learned how policy works. Now you will use that knowledge to create a simple policy that you can use to block access to port 80 and another to ensure encryption of data between two computers. The two major tools used to create policy are IP Security and Netsh. The next section describes how to cre ate a policy from the command line. The exercises at the end of this section teach you how to use the GUI tool and Netsh.

Netsh is a native Windows Server 2003 command-line scripting tool that you can use to display or modify the local or remote network configuration of a computer running Windows Server 2003. You can run Netsh from a batch file or from the command prompt. The Netsh IPSec commands cannot be used on any other Windows computer.
