+              The rapid growth of the Internet has astonished most observers. 
+              One reason that the Internet has grown so quickly is due to the 
+              flexibility of the original design. Without developing new 
+              methodologies of IP address assignment, this rapid growth of the 
+              Internet would have exhausted the current supply of IP addresses. In order to cope with a shortage of IP 
+              addresses, several solutions were developed. One widely 
+              implemented solution is Network Address Translation (NAT).<p>NAT is a mechanism for conserving registered IP addresses in large 
+              networks and simplifying IP addressing management tasks. As a 
+              packet is routed through a network device, usually a firewall or 
+              border router, the source IP address is translated from a private 
+              internal network address to a routable public IP address. This allows the packet to be transported over 
+              public external networks, such as the Internet. The public address 
+              in the reply is then translated back to the private internal 
+              address for delivery within the internal network. A variation of 
+              NAT, called Port Address Translation (PAT), allows many internal 
+              private addresses to be translated using a single external public 
+              address.</p>
+              <p>Routers, servers, and other key devices on the network usually require a static 
+              IP configuration, which is entered manually. However, desktop 
+              clients do not require a specific address but rather any one in a 
+              range of addresses. This range is typically within an IP subnet. A 
+              workstation within a specific subnet can be assigned any address 
+              within a range while other values are static, including the subnet 
+              mask, default gateway, and DNS server.</p>
+              <p>The Dynamic Host Configuration Protocol (DHCP) was designed to 
+              assign IP addresses and other important network configuration 
+              information dynamically. Because desktop clients typically make up 
+              the bulk of network nodes, DHCP is an extremely useful timesaving 
+              tool for network administrators.</p>
+              <p>Students completing this module should be able to:</p>

+          NAT translations can be used for a variety of purposes and can be 
+          either dynamically or statically assigned. Static NAT is designed to 
+          allow one-to-one mapping of local and global addresses. This is 
+          particularly useful for hosts which must have a consistent address 
+          that is accessible from the Internet. Such hosts may be enterprise 
+          servers or networking devices.<p>Dynamic NAT is designed to map a 
+          private IP address to a public address. Any IP address from a pool of 
+          public IP addresses is assigned to a network host. Overloading, or 
+          Port Address Translation (PAT), maps multiple private IP addresses to 
+          a single public IP address. Multiple addresses can be mapped to a 
+          single address because each private address is tracked by a port 
+          number.
+          <font face="Arial" size="2" COLOR="#000000">
+        <img border="0" src="../../images/1.gif" align="absmiddle" width="12" height="12"></font><p>PAT uses 
+          unique source port numbers on the inside global IP address to 
+          distinguish between translations. 
+          <font face="Arial" size="2" COLOR="#000000">
+        <img border="0" src="../../images/2.gif" align="absmiddle" width="12" height="12"> </font>The port 
+          number is encoded in 16 bits. The total number of internal addresses 
+          that can be translated to one external address could theoretically be 
+          as high as 65,536 per IP address. Realistically, the number of ports 
+          that can be assigned a single IP address is around 4000. PAT will attempt to 
+          preserve the original source port. If this source port is already 
+          used, PAT will assign the first available port number starting from 
+          the beginning of the appropriate port group 0-511, 512-1023, or 
+          1024-65535. When there are no more ports available and there is more 
+          than one external IP address configured, PAT moves to the next IP 
+          address to try to allocate the original source port again. This 
+          process continues until it runs out of available ports and external IP 
+          addresses.<p>NAT offers the following benefits:<ul>
+              <li>Eliminates reassigning each host a new IP address when 
+              changing to a new ISP. NAT eliminates the need to readdress all 
+              hosts that require external access, saving time and money.</li>
+              <li>Conserves addresses through application port-level 
+              multiplexing. With PAT, internal hosts can share a single public 
+              IP address for all external communications. In this 
+              type of configuration, very few external addresses are required to 
+              support many internal hosts, thereby conserving IP addresses.</li>
+              <li>Protects network security. Because private networks do not 
+              advertise their addresses or internal topology, they remain 
+              reasonably secure when used in conjunction with NAT to gain 
+              controlled external access.</li>

+            <li>
+
+          <font face="Arial" size="2">Increases the flexibility of connections 
+          to the public network. Multiple pools, backup pools, and load 
+          balancing pools can be implemented to assure reliable public network 
+          connections. </font>
+            </li>
+            <li>
+
+          <font face="Arial" size="2">Consistency of the internal network 
+          addressing scheme. On a network without private IP addresses and NAT, 
+          changing public IP addresses requires the renumbering of all hosts on 
+          the existing network. The costs of renumbering hosts can be 
+          significant. NAT allows the existing scheme to remain while supporting 
+          a new public addressing scheme. </font></li>
+          </ul>
+          <p>
+
+          <font FACE="Arial" SIZE="2">
+          NAT is not without drawbacks. Enabling address translation will cause 
+          a loss of functionality, particularly with any protocol or application 
+          that involves sending IP address information inside the IP payload. 
+          This requires additional support by the NAT device.</font></p>
+          <p>
+
+          <font face="Arial" size="2">NAT increases delay. Switching path delays 
+          are introduced because of the translation of each IP address within 
+          the packet headers.</font></p>
+          <p>
+
+          <font face="Arial" size="2">Performance may be a consideration because 
+          NAT is currently accomplished by using process switching. The CPU must 
+          look at every packet to decide whether it has to translate it. The CPU 
+          must alter the IP header, and possibly alter the TCP header.</font></p>
+          <p>
+
+          <font FACE="Arial" SIZE="2">
+          One significant disadvantage when implementing and using NAT is the 
+          loss of end-to-end IP traceability. It becomes much more difficult to 
+          trace packets that undergo numerous packet address changes over 
+          multiple NAT hops. Hackers who want to determine the source of a 
+          packet will find it difficult to trace or obtain the original source 
+          or destination address. </font></p>
+          <p>
+
+          <font FACE="Arial" SIZE="2">
+          NAT also forces some applications that use IP addressing to stop 
+          functioning because it hides end-to-end IP addresses. Applications 
+          that use physical addresses instead of a qualified domain name will 
+          not reach destinations that are translated across the NAT router. 
+          Sometimes, this problem can be avoided by implementing static NAT 
+          mappings. </font></p>

+          <font face="Arial" size="2">Dynamic Host Configuration Protocol (DHCP) 
+          works in a client/server mode. DHCP enables DHCP clients on an IP 
+          network to obtain their configurations from a DHCP server. Less work 
+          is involved in managing an IP network when DHCP is used. The 
+          most significant configuration option the client receives from the 
+          server is its IP address. The DHCP protocol is described in RFC 2131.</font><p>
+
+          <font face="Arial" size="2">A DHCP client is included in most modern 
+          operating systems including the various Windows operating systems, 
+          Novell Netware, Sun Solaris, Linux, and MAC OS. The client requests 
+          addressing values from the network DHCP server.
+          <img border="0" src="../../images/1.gif" align="absmiddle" width="12" height="12"> This 
+          server manages the allocation of the IP addresses and will answer 
+          configuration requests from clients.
+          <img border="0" src="../../images/2.gif" align="absmiddle" width="12" height="12">
+          <img border="0" src="../../images/3.gif" align="absmiddle" width="12" height="12"> The DHCP 
+          server can answer requests for many subnets. DHCP is not intended for 
+          configuring routers, switches, and servers. These type of hosts all 
+          need to have static IP addresses.</font></p>
+          <p>
+
+          <font face="Arial" size="2">DHCP works by providing a process for a 
+          server to allocate IP information to clients. Clients lease the 
+          information from the server for an administratively defined period. 
+          When the lease expires the client must ask for another address, 
+          although the client is typically reassigned the same address.</font></p>
+          <p>
+
+          <font face="Arial" size="2">Administrators typically prefer a network 
+          server to offer DHCP services because these solutions are scalable and 
+          relatively easy to manage. Cisco routers can use a Cisco IOS feature 
+          set, Easy IP, to offer an optional, full-featured DHCP server. Easy IP leases configurations for 24 hours by default. 
+          This is useful in small offices and home offices where the home user 
+          can take advantage of DHCP and NAT without having an NT or UNIX 
+          server. </font>
+          </p>
+          <p>
+
+          <font face="Arial" size="2">Administrators set up DHCP servers to 
+          assign addresses from predefined pools. DHCP servers can also offer 
+          other information, such as DNS server addresses, WINS server 
+          addresses, and domain names. Most DHCP servers also allow the 
+          administrator to define specifically what client MAC addresses can be 
+          serviced and automatically assign them the same IP address each time.

+          BOOTP protocol to enable configuration of diskless workstations. BOOTP 
+          was originally defined in RFC 951 in 1985. As the predecessor of DHCP, 
+          BOOTP shares some operational characteristics. Both protocols are 
+          client/server based and use UDP ports 67 and 68. Those ports are still 
+          known as BOOTP ports.</font><p><font face="Arial" size="2">The four 
+          basic IP parameters:</font><ul>
+            <li><font face="Arial" size="2">IP address</font></li>
+            <li><font face="Arial" size="2">Gateway address</font></li>

+            <p><font face="Arial" size="2">BOOTP does not dynamically 
+            allocate IP addresses to a host. When a client requests an IP address, the BOOTP server 
+          searches a predefined table for an entry that matches the MAC address 
+          for the client. If an entry exists, then the corresponding IP address 
+          for that entry is returned to the client. This means that the binding 
+          between the MAC address and the IP address must have already been 
+          configured in the BOOTP server.</font><p><font face="Arial" size="2">
+          There are two primary differences between DHCP and BOOTP:

+            <li><font face="Arial" size="2">DHCP defines mechanisms through 
+            which clients can be assigned an IP address for a finite lease 
+            period. This lease period allows for reassignment of the IP address 
+            to another client later, or for the client to get another 
+            assignment, if the client moves to another subnet. Clients may also 
+            renew leases and keep the same IP address.</font></li>

+          <ol>
+            <li>
+            A client must have DHCP configured when starting the network 
+            membership process. The client sends a request to a server 
+            requesting an IP configuration. Sometimes the client may suggest 
+            the IP address it wants, such as when requesting an extension to a DHCP lease. The client locates a DHCP server by sending a broadcast 
+            called a DHCPDISCOVER. </li>
+            <li>
+            When the server receives the broadcast, it determines whether it can 
+            service the request from its own database. If it cannot, the server 
+            may forward the request on to another DHCP server. If it can, the DHCP server offers the client IP 
+            configuration information in the form of a unicast DHCPOFFER. The 
+            DHCPOFFER is a proposed configuration that may include IP address, 
+            DNS server address, and lease time.</li>
+            <li>
+            If the 
+            client finds the offer agreeable, it will send another broadcast, a DHCPREQUEST, specifically requesting those particular IP parameters. 
+            Why does the client broadcast the request instead of unicasting it 
+            to the server? A broadcast is used because the first message, the DHCPDISCOVER, may have reached more than one DHCP server. If more 
+            than one server makes an offer, the broadcasted DHCPREQUEST allows 
+            the other servers to know which offer was accepted. The offer 
+            accepted is usually the first offer received. </li>
+            <li>
+            The server that 
+            receives the DHCPREQUEST makes the configuration official by sending 
+            a unicast acknowledgment, the DHCPACK. It is possible, but highly 
+            unlikely, that the server will not send the DHCPACK. This may happen 
+            because the server may have leased that information to another 
+            client in the interim. Receipt of the DHCPACK message enables the 
+            client to begin using the assigned address immediately. </li>
+            <li>
+            If the client detects that the address is already in use on the 
+            local segment it will send a DHCPDECLINE message and the process 
+            starts again. If the client received a DHCPNACK from the server after 
+            sending the DHCPREQUEST, then it will restart the process again.</li>
+            <li>
+            If the client no longer needs 
+            the IP address, the client sends a DHCPRELEASE message to the 
+            server.</font></li>
+          </ol>
+          <p><font face="Arial" size="2"> 
+          Depending on an organization's policies, it may be possible for an end 
+          user or an administrator to statically assign a host an IP address 
+          that belongs in the DHCP servers address pool. Just in case, the Cisco 
+          IOS DHCP server always checks to make sure that an address is not in 
+          use before the server offers it to a client. The server will issue an 
+          ICMP echo request, or will ping, to a pool address before sending the 
+          DHCPOFFER to a client. Although configurable, the default number of 
+          pings used to check for a potential IP address conflict is two.</font></p>

+          DHCP clients use IP broadcasts to find the DHCP server on the segment. 
+          What happens when the server and the client are not on the same 
+          segment and are separated by a router? Routers do not forward these 
+          broadcasts.</font><p>
+          <font FACE="Arial" SIZE="2">
+          DHCP is not the only critical service that uses broadcasts. Cisco 
+          routers and other devices may use broadcasts to locate TFTP servers. 
+          Some clients may need to broadcast to locate a TACACS server. A TACACS 
+          server is a security server. Typically, in a complex hierarchical 
+          network, clients reside on the same subnet as key servers. Such remote 
+          clients will broadcast to locate these servers. However, routers, by 
+          default, will not forward client broadcasts beyond their subnet.</font></p>
+          <p>
+          <font FACE="Arial" SIZE="2">
+          Because some clients are useless without services such as DHCP, one of 
+          two choices must be implemented. The administrator will need to place 
+          servers on all subnets or use the Cisco IOS helper address feature. 
+          Running services such as DHCP or DNS on several computers creates 
+          overhead and administrative difficulties making the first option 
+          inefficient. When possible, administrators should use the </font>
+          <font FACE="Courier New" SIZE="2">
+          <b>ip helper-address</b></font><font FACE="Arial" SIZE="2">
+          command to relay broadcast requests for these key UDP services.</font></p>
+          <p>
+          <font FACE="Arial" SIZE="2">
+          By using the helper address feature, a router can be configured to 
+          accept a broadcast request for a UDP service and then forward it as a 
+          unicast to a specific IP address. By default, the </font>

+          In the particular case of DHCP, a client broadcasts a DHCPDISCOVER 
+          packet on its local segment.
+          <img border="0" src="../../images/1.gif" align="absmiddle" width="12" height="12"> This 
+          packet is picked up by the gateway. If a helper-address is configured, 
+          the DHCP packet is forwarded to the specified address. Before 
+          forwarding the packet, the router fills in the GIADDR field of the 
+          packet with the IP address of the router for that segment. This 
+          address will then be the gateway address for the DHCP client, when it 
+          gets the IP address.

+          The DHCP server receives the discover packet. The server uses the GIADDR field to index into the list of address pools, to find one 
+          which has the gateway address set to the value in GIADDR. This pool is 
+          then used to supply the client with its IP address.
