Real World L2TP Troubleshooting If you have trouble connecting via L2TP, try establishing an L2TP VPN connection from inside the internal network (this tests whether the problem is in the firewall configuration). Check Event Viewer and use Network Monitor to perform a network capture, if necessary. L2TP connections might not work properly if the client computer is behind a NAT firewall. If you receive Error 778 or Error 801 on the client when establishing a VPN connection, verify that the Windows Small Business Server enterprise root CA certificate appears in the list of Trusted Root Certification Authorities, and that the correct server certificate is used by IAS (see the Modifying the Small Business Remote Access Policy section earlier in this chapter). Clearing the Validate Server Certificate check box in the Advanced Security Settings dialog box on the client can also resolve these errors, though at the expense of mutual authentication.

Securing 802.11 (Wi-Fi) networks is a subject of much debate and a myriad of options. (See the Real World sidebar, Wireless Security Strategies, appearing later in this chapter.) One of the most sophisticated methods of securing an 802.11 network is using 802.1X authentication in conjunction with WEP or WPA encryption. Although setting up 802.1X authentication evokes panic in the hearts of many administrators due to its complexity, it s not as hard as you might think, especially when done in a simplified manner suitable for small businesses, as discussed in the following sections.

If no songs are listed in the playlist, click All Audio on the drop-down list to display a list of available audio tracks, and start a song. 6. Click the Select visualization or album art button, and then click Musical Colors on the drop-down list. The visualization changes to reflect the first of the Musical Colors options, Night Lights:

Deploying 802.1X authentication is a complex process, so it s extremely important to carefully follow the steps in each section, doublecheck your work, and not skip any sections.

Real World Wireless Security Strategies There are a number of strategies for securing wireless 802.11a/b/g networks:

broadcasting and using static IP addresses for clients, MAC address filtering can be hacked easily with a network sniffer, requires a lot of administrative work and hassle, and is a complete waste of time.

secures a network against casual hacking attempts, but is easily defeated by monitoring network traffic for an extended period of time (which can be as short as several hours on a busy network even when 128-bit keys are used). WEP encryption also requires manually typing long encryption keys on all clients and access points, which can be a nuisance. To maximize security with WEP, change encryption keys weekly if possible.

for wireless networks, but you must manually type network keys on all clients and access points, unless 802.1X authentication is used. Not all client operating systems support WPA yet only newer access points support it and WPA can be easily compromised when the keys used aren t long (128 bits), randomly generated strings.

of securing wireless networks is to place access points in a perimeter network and have clients establish a VPN connection to access the internal network. However, there is some performance impact; Group Policy Computer Configuration doesn t work over VPN links; and remote administration of clients only works while the VPN is connected.

WPA encryption is very secure (keys are generated dynamically and mutual authentication occurs) and offers the most seamless client experience authentication takes place using the user account and digital signatures. This is the preferred wireless solution by Microsoft; however, it does require additional configuration on the server and clients, as well as access points that support 802.1X authentication.

The 802.1X authentication standard requires the use of an authentication protocol. There are two worth considering:

Microsoft Challenge Handshake Authentication Protocol version 2 (MS-CHAP v2)

Extensible Authentication Protocol-Transport Layer Security (EAP-TLS)
