P-320W User’s Guide H A P T E R Network Address Translation (NAT) This chapter discusses how to configure NAT on the Prestige. 8.1 NAT Overview NAT (Network Address Translation - NAT, RFC 1631) is the translation of the IP address of a host in a packet.
P-320W User’s Guide Table 40 NAT Definitions TERM DESCRIPTION Inside This refers to the host on the LAN. Outside This refers to the host on the WAN. Local This refers to the packet address (source or destination) as the packet travels on the LAN.
P-320W User’s Guide Figure 54 How NAT Works 8.1.4 NAT Application The following figure illustrates a possible NAT application, where three inside LANs (logical LANs using IP Alias) behind the Prestige can communicate with three distinct WAN networks. More examples follow at the end of this chapter.
P-320W User’s Guide Note: If you do not assign a Default Server IP Address, the Prestige discards all packets received for ports that are not specified in this screen or remote management. 8.1.6 Port Forwarding: Services and Port Numbers A SUA server set is a list of inside (behind NAT on the LAN) servers, for example, web or FTP, that you can make accessible to the outside world even though NAT makes your whole inside network appear as a single machine to the outside world.
P-320W User’s Guide 8.1.7 Configuring Servers Behind SUA (Example) Let's say you want to assign ports 21-25 to one FTP, Telnet and SMTP server (A in the example), port 80 to another (B in the example) and assign a default server IP address of 192.168.1.35 to a third (C in the example).
P-320W User’s Guide 8.3 Port Forwarding Screen Ordering your rules is important because the Prestige applies the rules in the order that you specify. When a rule matches the current packet, the Prestige takes the corresponding action and the remaining rules are ignored. If there are any empty rules before your new configured rule, your configured rule will be pushed up by that number of empty rules.
P-320W User’s Guide The following table describes the labels in this screen. Table 43 NAT: Port Forwarding LABEL DESCRIPTION Default Server In addition to the servers for specified services, NAT supports a default server.

P-320W User’s Guide P P E N D I X IP Subnetting IP Addressing Routers “route” based on the network number. The router that delivers the data packet to the correct destination host uses the host ID. IP Classes An IP address is made up of four octets (eight bits), written in dotted decimal notation, for example, 192.168.1.1.
P-320W User’s Guide Since the first octet of a class “A” IP address must contain a “0”, the first octet of a class “A” address can have a value of 0 to 127. Similarly the first octet of a class “B” must begin with “10”, therefore the first octet of a class “B”...

P-320W User’s Guide Note: In the following charts, shaded/bolded last octet bit values indicate host ID bits “borrowed” to form network ID bits. The number of “borrowed” host ID bits determines the number of subnets you can have. The remaining number of host ID bits (after “borrowing”) determines the number of hosts you can have...
P-320W User’s Guide Example: Four Subnets The above example illustrated using a 25-bit subnet mask to divide a class “C” address space into two subnets. Similarly to divide a class “C” address into four subnets, you need to “borrow” two host ID bits to give four possible combinations of 00, 01, 10 and 11. The subnet mask is 26 bits (11111111.11111111.11111111.11000000) or 255.255.255.192.

P-320W User’s Guide PPTP Protocol Overview PPTP is very similar to L2TP, since L2TP is based on both PPTP and L2F (Cisco’s Layer 2 Forwarding). Conceptually, there are three parties in PPTP, namely the PNS (PPTP Network Server), the PAC (PPTP Access Concentrator) and the PPTP user. The PNS is the box that hosts both the PPP and the PPTP stacks and forms one end of the PPTP tunnel.
P-320W User’s Guide Figure 137 Example Message Exchange between Computer and an ANT PPP Data Connection The PPP frames are tunneled between the PNS and PAC over GRE (General Routing Encapsulation, RFC 1701, 1702).

P-320W User’s Guide P P E N D I X Wireless LANs Wireless LAN Topologies This section discusses ad-hoc and infrastructure wireless LAN topologies. Ad-hoc Wireless LAN Configuration The simplest WLAN configuration is an independent (Ad-hoc) WLAN that connects a set of computers with wireless stations (A, B, C).
P-320W User’s Guide Figure 139 Basic Service Set An Extended Service Set (ESS) consists of a series of overlapping BSSs, each containing an access point, with each access point connected together by a wired network. This wired connection between APs is called a Distribution System (DS).
P-320W User’s Guide Figure 140 Infrastructure WLAN Channel A channel is the radio frequency(ies) used by IEEE 802.11a/b/g wireless devices. Channels available depend on your geographical area. You may have a choice of channels (for your region) so you should use a different channel than an adjacent AP (access point) to reduce interference.
P-320W User’s Guide Figure 141 RTS/CTS When station A sends data to the AP, it might not know that the station B is already using the channel. If these two stations send data at the same time, collisions may occur when both sets of data arrive at the AP at the same time, resulting in a loss of messages for both stations.
P-320W User’s Guide A large Fragmentation Threshold is recommended for networks not prone to interference while you should set a smaller threshold for busy networks or networks that are prone to interference. If the Fragmentation Threshold value is smaller than the RTS/CTS value (see previously) you set then the RTS (Request To Send)/CTS (Clear to Send) handshake will never occur as data frames will be fragmented before they reach RTS/CTS size.
P-320W User’s Guide IEEE 802.1x In June 2001, the IEEE 802.1x standard was designed to extend the features of IEEE 802.11 to support extended authentication as well as providing additional accounting and control features. It is supported by Windows XP and a number of network devices. Some advantages of IEEE 802.1x are:...
P-320W User’s Guide • Access-Challenge Sent by a RADIUS server requesting more information in order to allow access. The access point sends a proper response from the user and then sends another Access- Request message. The following types of RADIUS messages are exchanged between the access point and the RADIUS server for user accounting: •...
P-320W User’s Guide 3 The wireless station replies with identity information, including username and password. 4 The RADIUS server checks the user information against its user profile database and determines whether or not to authenticate the wireless station. Types of Authentication This section discusses some popular authentication types: EAP-MD5, EAP-TLS, EAP- TTLS, PEAP and LEAP.
P-320W User’s Guide PEAP (Protected EAP) Like EAP-TTLS, server-side certificate authentication is used to establish a secure connection, then use simple username and password methods through the secured connection to authenticate the clients, thus hiding client identity. However, PEAP only supports EAP methods, such as EAP-MD5, EAP-MSCHAPv2 and EAP-GTC (EAP-Generic Token Card), for client authentication.
P-320W User’s Guide Figure 143 WEP Authentication Steps Open system authentication involves an unencrypted two-message procedure. A wireless station sends an open system authentication request to the AP, which will then automatically accept and connect the wireless station to the network. In effect, open system is not authentication at all as any station can gain access to the network.
P-320W User’s Guide Note: EAP-MD5 cannot be used with Dynamic WEP Key Exchange For added security, certificate-based authentications (EAP-TLS, EAP-TTLS and PEAP) use dynamic keys for data encryption. They are often deployed in corporate environments, but for public deployment, a simple user name and password pair is more practical. The following table is a comparison of the features of authentication types.
P-320W User’s Guide The Message Integrity Check (MIC) is designed to prevent an attacker from capturing data packets, altering them and resending them. The MIC provides a strong mathematical function in which the receiver and the transmitter each compute and then compare the MIC. If they do not match, it is assumed that the data has been tampered with and the packet is dropped.
P-320W User’s Guide In a network environment with multiple access points, wireless stations are able to switch from one access point to another as they move between the coverage areas. This is roaming. As the wireless station moves from place to place, it is responsible for choosing the most appropriate access point depending on the signal strength, network utilization or other factors.
P-320W User’s Guide Requirements for Roaming The following requirements must be met in order for wireless stations to roam between the coverage areas. 1 All the access points must be on the same subnet and configured with the same ESSID.
P-320W User’s Guide P P E N D I X Antenna Selection and Positioning Recommendation An antenna couples RF signals onto air. A transmitter within a wireless device sends an RF signal to the antenna, which propagates the signal through the air. The antenna also operates in reverse by capturing RF signals from the air.
P-320W User’s Guide Types of Antennas For WLAN There are two types of antennas used for wireless LAN applications. • Omni-directional antennas send the RF signal out in all directions on a horizontal plane. The coverage area is torus-shaped (like a donut) which makes these antennas ideal for a room environment.
