Page 60
Chapter 5 Wireless A good way to come up with effective security keys, passwords and so on is to use obscure information that you personally will easily remember, and to enter it in a way that appears random and does not include real words. For example, if your mother owns a 1970 Dodge Challenger and her favorite movie is Vanishing Point (which you know was made in 1971) you could use “70dodchal71vanpoi”...
Chapter 5 Wireless For example, if the wireless network has a RADIUS server, you can choose WPA or WPA2. If users do not log in to the wireless network, you can choose no encryption, Static WEP, WPA-PSK, or WPA2-PSK. Usually, you should set up the strongest encryption that every device in the wireless network supports.
Chapter 5 Wireless When Intra-BSS traffic blocking is enabled, wireless station A and B can still access the wired network but cannot communicate with each other. Figure 33 Basic Service set 5.8.5 MBSSID Traditionally, you need to use different APs to configure different Basic Service Sets (BSSs). As well as the cost of buying extra APs, there is also the possibility of channel interference.
Page 63
Chapter 5 Wireless WPS allows you to quickly set up a wireless network with strong security, without having to configure security settings manually. Each WPS connection works between two devices. Both devices must support WPS (check each device’s documentation to make sure). Depending on the devices you have, you can either press a button (on the device itself, or in its configuration utility) or enter a PIN (a unique Personal Identification Number that allows one device to authenticate the other) in each of the two devices.
Page 64
Chapter 5 Wireless Ensure WPS is enabled on both devices. Access the WPS section of the AP’s configuration interface. See the device’s User’s Guide for how to do this. Look for the client’s WPS PIN; it will be displayed either on the device, or in the WPS section of the client’s configuration interface (see the device’s User’s Guide for how to find the WPS PIN - for the LTE Device, see Section 5.4 on page...

Chapter 16 VPN Figure 107 Transport and Tunnel Mode IPSec Encapsulation Transport Mode Transport mode is used to protect upper layer protocols and only affects the data in the IP packet. In Transport mode, the IP packet contains the security protocol (AH or ESP) located after the original IP header and options, but before any upper layer protocols contained in the packet (such as TCP and UDP).
Chapter 16 VPN Figure 108 Two Phases to Set Up the IPSec SA In phase 1 you must: • Choose a negotiation mode. • Authenticate the connection by entering a pre-shared key. • Choose an encryption algorithm. • Choose an authentication algorithm. •...
Chapter 16 VPN • Aggressive Mode is quicker than Main Mode because it eliminates several steps when the communicating parties are negotiating authentication (phase 1). However the trade-off is that faster speed limits its negotiating power and it also does not provide identity protection. It is useful in remote access situations where the address of the initiator is not know by the responder and both parties want to use pre-shared key authentication.
Chapter 16 VPN Figure 109 NAT Router Between IPSec Routers Normally you cannot set up an IKE SA with a NAT router between the two IPSec routers because the NAT router changes the header of the IPSec packet. NAT traversal solves the problem by adding a UDP port 500 header to the IPSec packet.
Chapter 16 VPN The type of ID can be a domain name, an IP address or an e-mail address. The content is the IP address, domain name, or e-mail address. Table 66 Local ID Type and Content Fields LOCAL ID TYPE= CONTENT= Type the IP address of your computer.

Chapter 17 VoIP After successful registration, the SIP server knows that the users (identified by their dedicated SIP URIs) are represented by the UA, and knows the IP address to which the SIP requests and responses should be sent. Registration is initiated by the User Agent Client (UAC) running in the VoIP gateway (the LTE Device).
Page 181
Chapter 17 VoIP The client device (A in the figure) sends a call invitation to the SIP proxy server B. The SIP proxy server forwards the call invitation to C. Figure 119 SIP Proxy Server SIP Redirect Server A SIP redirect server accepts SIP requests, translates the destination address to an IP address and sends the translated IP address back to the device that sent the request.
Page 182
Chapter 17 VoIP Client device A then sends the call invitation to client device C. Figure 120 SIP Redirect Server SIP Register Server A SIP register server maintains a database of SIP identity-to-IP address (or domain name) mapping. The register server checks your user name and password when you register. When you make a VoIP call using SIP, the RTP (Real time Transport Protocol) is used to handle voice data transfer.
Chapter 17 VoIP A sends a SIP INVITE request to B. This message is an invitation for B to participate in a SIP telephone call. B sends a response indicating that the telephone is ringing. B sends an OK response after the call is answered. A then sends an ACK message to acknowledge that B has answered the call.
Chapter 17 VoIP Type of Service (ToS) Network traffic can be classified by setting the ToS (Type of Service) values at the data source (for example, at the LTE Device) so a server can decide the best method of delivery, that is the least cost, fastest route and so on.
