Firewall 71Firewall This section is for configuration settings of the Router’s firewall function.Your Router is equipped with a firewall that will protect your network from a wide array of common hacker attacks including Ping of Death (PoD) and Denial of Service (DoS) attacks. You can turn the firewall function off if needed. Turning off the firewall protection will not leave your network completely vulnerable to hacker attacks, but 3Com recommends that you leave the firewall enabled whenever possible.SPI Stateful Packet Inspection (SPI) - The Intrusion Detection Feature of the Router limits access for incoming traffic at the WAN port.This feature is called a "stateful" packet inspection, because it examines the contents of the packet to determine the state of the communications; i.e., it ensures that the stated destination computer has previously requested the current communication. This is a way of ensuring that all communications are initiated by the recipient computer and are taking place only with sources that are known and trusted from previous interactions. In addition to being more rigorous in their inspection of packets, stateful inspection firewalls also close off ports until connection to the specific port is requested. Figure 57 Firewall Screen
72 CHAPTER 5: CONFIGURING THE ROUTERTo enable the firewall function:1Select the level of protection (High, Medium, or Low) that you desire from the Firewall level drop-down menu.2Click Apply.■For low and medium levels of firewall protection, refer to Figure 58.■For high level of firewall protection, refer to Figure 59.Figure 58 Low and Medium Level Firewall Protection ScreenWhen abnormal network activity occurs, an alerting email will be sent out to you. Enter the following information to receive the email:■Your E-mail Address ■SMTP Server Address■User name ■Password
Firewall 73Figure 59 High Level Firewall Protection Screen If you select high level of protection, you will need to configure additional parameters for the firewall. ■Fragmentation half-open wait - Configures the number of seconds that a packet state structure remains active. When the timeout value expires, the Router drops the un-assembled packet, freeing that structure for use by another packet. ■TCP SYN wait - Defines how long the software will wait for a TCP session to synchronize before dropping the session. ■TCP FIN wait - Specifies how long a TCP session will be maintained after the firewall detects a FIN packet. ■TCP connection idle timeout - The length of time for which a TCP session will be managed if there is no activity. ■UDP session idle timeout - The length of time for which a UDP session will be managed if there is no activity.■H.323 data channel idle timeout - The length of time for which an H.323 session will be managed if there is no activity.
74 CHAPTER 5: CONFIGURING THE ROUTER■Total incomplete TCP/UDP sessions HIGH - Defines the rate of new unestablished sessions that will cause the software to start deleting half-open sessions.■Total incomplete TCP/UDP sessions LOW - Defines the rate of new unestablished sessions that will cause the software to stop deleting half-open sessions.■Incomplete TCP/UDP sessions (per min) HIGH - Maximum number of allowed incomplete TCP/UDP sessions per minute.■Incomplete TCP/UDP sessions (per min) LOW - Minimum number of allowed incomplete TCP/UDP sessions per minute. ■Maximum incomplete TCP/UDP sessions number from same host - Maximum number of incomplete TCP/UDP sessions from the same host. ■Incomplete TCP/UDP sessions detect sensitive time period - Length of time before an incomplete TCP/UDP session is detected as incomplete.■Maximum half-open fragmentation packet number from same host - Maximum number of half-open fragmentation packets from the same host.■Half-open fragmentation detect sensitive time period - Length of time before a half-open fragmentation session is detected as half-open.■Flooding cracker block time - Length of time from detecting a flood attack to blocking the attack.

Then select the row that you want to copy the settings to from the Copy To drop-down menu, and click Copy To. The settings will be transferred to the row that you specified. Click Apply to save the setting for that application.If your application is not listed, you will need to check with the application vendor to determine which ports need to be configured. You can manually enter the port information into the Router. To manually enter the port information: 1Specify the trigger port (the one used by the application when it is initialized) in the Trigger Port column, and specify whether the trigger is TCP or UDP.2Specify the Public Ports used by the application, that will need to be opened up in the firewall for the application to work properly. Also specify whether these ports are TCP or UDP.3Check the Enabled checkbox, then click Apply.
76 CHAPTER 5: CONFIGURING THE ROUTERVirtual Servers The Virtual servers feature allows you to route external (Internet) calls for services such as a web server (port 80), FTP server (Port 21), or other applications through your Router to your internal network. Since your internal computers are protected by a firewall, machines from the Internet cannot get to them because they cannot be 'seen'.If you need to configure the Virtual Server function for a specific application, you will need to contact the application vendor to find out which port settings you need. The maximum number of virtual servers that can be configured is 20. Figure 61 Virtual Servers ScreenA list of popular servers has been included to choose from. Select the server from the Popular servers drop-down menu. Then click Add, your selection will be added to the table.

82 CHAPTER 5: CONFIGURING THE ROUTERAdvanced The Advanced section allows you to set additional parameter details for the Router. You can configure:■Security■VLAN■Static Routes■RIP■DDNS■SNMP■Syslog■Proxy Arp■QoS SettingsSecurity Use the Security screen to set the advanced security settings for the Router.Figure 68 Security Screen
Advanced 83■NAT — Before you enable NAT (Network Address Translation), make sure you have changed the administrator password. NAT is the method by which the Router shares the single IP address assigned by your ISP with the computers on your network. This function should only be disabled by advanced users, and if your ISP assigns you multiple IP addresses or you need NAT disabled for an advanced system configuration. If you have a single IP address and you turn NAT off, the computers on your network will not be able to access the Internet. Other problems may also occur. ■IPSEC NAT-T Pass-through — NAT-T (NAT Traversal) is an Internet Draft proposed to IETF in order to help the problems associated with passing IPsec traffic through NAT Routers. For NAT-T to work, both ends of the connection need to support this function. Ensure that you select NAT-T only if it is needed as it will reduce LAN-WAN throughput. This Router supports NAT-T draft 2 implementation.■Universal Plug and Play — This is a technology that offers seamless operation of voice messaging, video messaging, games, and other applications that are Universal Plug and Play compliant. Some applications require the Router's firewall to be configured in a specific way to operate properly. This usually requires opening TCP and UDP ports and in some instances setting trigger ports. An application that is Universal Plug and Play compliant has the ability to communicate with the Router, basically "telling" the Router which way it needs the firewall configured. The Router ships with the Universal Plug and Play feature disabled. If you are using any applications that are Universal Plug and Play compliant, and want to take advantage of the Universal Plug and Play features, you can enable this feature. Simply check the Enable Universal Plug and Play checkbox. Click Apply to save the change.■WAN Ping Blocking — Computer hackers use what is known as "Pinging" to find potential victims on the Internet. By pinging a specific IP address and receiving a response from the IP address, a hacker can determine that something of interest might be there. The Router can be set up so it will not respond to an Internet Control Message Protocol (ICMP) Ping from the outside. This heightens the level of security of your Router. To turn off the ping response, check Block ICMP Ping and click Apply; the Router will not respond to an ICMP ping from the Internet.
84 CHAPTER 5: CONFIGURING THE ROUTER■MSS Clamping — You might not be able to browse some Web sites or to send email messages that contain attachments from an Internet Connection Sharing client computer if your outbound connection is through a Windows XP-based Internet Connection Sharing host computer that uses Point-to-Point Protocol over Ethernet (PPPoE). This issue may occur if the Windows XP-based Internet Connection Sharing host computer uses a smaller Maximum Transmission Unit (MTU) size on the WAN interface (the PPPoE connection to the Internet) than it uses on the private interface (the Ethernet connection to the Internet Connection Sharing client). If a packet is larger than the MTU size on the WAN interface, the client sends an Internet Control Message Protocol (ICMP) error to the external server to request that the server negotiate the TCP Maximum Segment Size (MSS). However, this message may be blocked by some firewalls. When this occurs, the packet is dropped. To allow the message to go through the firewall, enable MSS Clamping. MSS clamping will make Internet Connection Sharing set the MSS value low enough to match the external interface. ■Remote Administration — This feature allows you to make changes to your Router’s settings from anywhere on the Internet. Four options are available: ■If you do not want to use this feature, select Disable Remote Administration.■Select Enable administration from a single Internet Host, and enter the IP address, to allow only one computer to use the remote administration. This is more secure, as only the specified IP address will be able to manage the Router.■Select Enable administration from a whole Subnet Internet Host, and enter the IP address and subnet mask, to allow PCs from that specific subnet group to use the remote administration.■Select Enable administration from any Internet Host, this allows any computer to access the Router remotely. Before you enable this function, ensure that you have set the Administration Password.
Advanced 85VLAN The VLAN screen allows you to setup VLAN groups. Figure 69 VLAN ScreenStatic Routes You can configure static routes in this screen. Figure 70 Static Routes ScreenTo add a static route entry to the table, click Add (see Figure 71).To change an existing entry, click Edit. To delete an entry, click Delete.
86 CHAPTER 5: CONFIGURING THE ROUTERFigure 71 Add Static Route ScreenEnter the following information: ■Index — the index of the entry.■Network Address — the network address of the static route. ■Subnet Mask — the subnet mask of the route.A network address of 0.0.0.0 and a subnet mask of 0.0.0.0 indicates the default route.■Gateway — the router used to route data to the network specified by the network address.■Interface — select the interface. After you have finished making changes to the table, click Apply.
Advanced 87RIP RIP (Routing Information Protocol) - RIP allows the network administrator to set up routing information on one RIP-enabled device and send that information to all RIP-enabled devices on the network. Figure 72 RIP Parameter ScreenYou can set up RIP independently on both LAN and WAN interfaces.1Check the Enable RIP checkbox. 2Check the Enable Auto summary checkbox. Auto summarization sends simplified routing data to other RIP-enabled devices rather than full routing data.3Select the Operation Mode:■Disable — RIP is not enabled for the WAN or LAN interface.■Enable — RIP is enabled for the WAN or LAN interface. The router will transmit RIP update information to other RIP-enabled devices.■Silent — RIP is enabled, however the Router only receives RIP update messages, it will not transmit any messages itself.4In the Version field, select 1 or 2.3Com recommends that you only use RIPv1 if there is an existing RIP-enabled device on your network that does not support RIPv2. In all other cases, you should use RIPv2.
88 CHAPTER 5: CONFIGURING THE ROUTER5Use the Poison Reverse drop-down menu to enable or disable Poison Reverse on the Router. Enabling Poison Reverse on your Router allows it to indicate to other RIP-enabled devices that they have both routes that point to each other, preventing data loops.6Use the Authentication Required field to choose the mode of authentication:■None — Switches off authentication on the specified interface.■Password — An unencrypted text password that needs to be set on all RIP-enabled devices connected to this Router. RIP information is not shared between devices whose passwords do not match.7In the Password field, enter the required password.8Click Apply.
Advanced 89DDNS The Router provides a list of dynamic DNS providers for you to choose from. Dynamic Domain Name Server (DDNS) enables you to map a static domain name to a dynamic IP address. Before you set up DDNS, you must obtain an account, password or key and static domain name from your DDNS provider. The Router supports five DDNS providers: ■DynDNS.org■TZO.com■Dt DNS.com■No-IP.com■Zoneedit.comFigure 73 Dynamic Domain Name Server (DDNS) Screen1Check Enable DDNS. 2Select the provider, and then enter the necessary information provided by your DDNS provider. 3Click Apply.
90 CHAPTER 5: CONFIGURING THE ROUTERSNMP SNMP (Simple Network Management Protocol) allows remote management of your Router by a PC that has an SNMP management agent installed.Check the Enable SNMP box, the table will appear. Figure 74 SNMP ScreenTo Configure SNMP Community:1In the Community column, enter the name of the SNMP communication channel. Your SNMP management agent needs to be configured with this name so that it can communicate with your Router.2In the Access column, select Read to allow the management agent to collect data (for example, bandwidth usage) from your Router. Select Write to allow the management agent to change the configuration of your Router.3Check the appropriate Valid checkbox to enable the communication channel.
Advanced 91You can configure your Router to send status messages to the SNMP management agent if a problem occurs on the network. To configure SNMP traps:1In the IP Address field, enter the IP address of the PC to which you want your Router to send status messages. 2In the Community field, enter the name of the SNMP communication channel to which you want your Router to send status messages.3Set the Version field to match the version of trap messaging that your SNMP management agent supports. The Router supports V1 and V2c trap messaging.Syslog Using third party syslog software, this Syslog Server tool will automatically download the Router log to the specified server IP address.Figure 75 Syslog Server Screen1Check the Enable Syslog Server checkbox.2Enter the Server LAN IP Address in the space provided. 3Click Apply.
92 CHAPTER 5: CONFIGURING THE ROUTERProxy ARP Proxy ARP is the technique in which one host, usually a Router, answers ARP requests intended for another machine. By “faking” its identity, the Router accepts responsibility for routing packets to the “real” or intended destination. This heightens the security for your network. Figure 76 Proxy ARP Screen1Check the Enable ProxyARP box. 2Enter the corresponding IP address in the IP Address From and IP Address To fields. 3Click Apply.
Advanced 93QoS Settings The QoS (Quality of Service) function allows you to differentiate your network traffic and provide it with high-priority forwarding service.The bandwidth gap between LAN and WAN may significantly degrade performance of critical network applications, such as VoIP, gaming, and VPN. This QoS function allows you to classify traffic of applications and provides them with differentiated services (Diffserv). Figure 77 QoS Settings Screen 1Check the Enable QoS box. 2Enter the value for WAN Out Bandwidth.3Define the minimum percentage of bandwidth for each type of traffic.4Check the corresponding box to allow more bandwidth allocation.5Click Apply.
94 CHAPTER 5: CONFIGURING THE ROUTERVPN The Router has a Virtual Private Network (VPN) feature that provides a secure link between remote users and the corporate network by establishing an authenticated and encrypted tunnel for passing secure data over the Internet. The Router supports three modes of VPN operation: ■IPsec (IP Security) — provides IP network-layer encryption. IPSec can support large encryption networks (such as the Internet) by using digital certificates for device authentication. When setting up an IPSec connection between two devices, make sure that they support the same encryption method.Note: Enabling IPSec VPN disables pass-through to IPSec and L2TP over IPSec Virtual Servers on the LAN. Pass-through outbound from clients on the LAN to servers on the Internet is unaffected.■PPTP (Point-to-Point Tunneling Protocol) — provides a secure tunnel for remote client access to a PPTP security gateway. It is not as secure as IPSec but is easy to administer. PPTP does not support gateway to gateway connections and is only suitable for connecting remote users. Check that your ISP’s routers support this protocol before you use it.Note: Enabling the PPTP Server disables PPTP pass-through to a Virtual Server on the LAN. Pass-through outbound from clients on the LAN to servers on the Internet is unaffected.■L2TP over IPSec — this is a combination of two protocols. L2TP is used to authenticate a user, and IPSec is used to encrypt data. L2TP over IPSec does not support gateway to gateway connections and is only suitable for connecting remote users. Check that your ISP’s routers support this protocol before you use it.Note: Enabling L2TP over IPSec disables pass-through to IPSec and L2TP over IPSec Virtual Servers on the LAN. Pass-through outbound from clients on the LAN to servers on the Internet is unaffected.Using the VPN Tunnel Configuration screen, you can add new IPSec, L2TP over IPSec and PPTP connections, and to edit existing connections. When adding or editing values on this screen remember that both ends of the connection must contain the same information.
VPN 951Check the Enable IPsec box. Figure 78 VPN Screen2Enter the Local ID Name of your VPN. 3Click Add to create a new entry. Figure 79 Add New VPN Tunnel Configuration Screen

6TROUBLESHOOTINGBasic Connection Checks■Check that the Router is connected to your computers and to the telephone line, and that all the equipment is powered on. Check that the LAN Status and SYNC LEDs on the Router are illuminated, and that any corresponding LEDs on the NIC are also illuminated.■Ensure that the computers have completed their start-up procedure and are ready for use. Some network interfaces may not be correctly initialized until the start-up procedure has completed.■If the link status LED does not illuminate for a port that is connected, check that you do not have a faulty cable. Try a different cable.Browsing to the Router Configuration ScreensIf you have connected your Router and computers together but cannot browse to the Router configuration screens, check the following:■Confirm that the physical connection between your computer and the Router is OK, and that the LAN Status LEDs on the Router and network adapter are illuminated and indicating the same speed (10Mbps or 100Mbps). Some NICs do not have status LEDs, in which case a diagnostic program may be available that can give you this information.■Ensure that you have configured your computer as described in Chapter 3. Restart your computer while it is connected to the Router to ensure that your computer receives an IP address.■When entering the address of the Router into your web browser, ensure that you use the full URL including the http:// prefix (e.g. http://192.168.1.1).■Ensure that you do not have a Web proxy enabled on your computer. Go to the Control Panel and click on Internet Options. Select the Connections tab and click on the LAN Settings button at the bottom. Make sure that the Proxy Server option is unchecked.
108 CHAPTER 6: TROUBLESHOOTING■If you cannot browse to the Router, use the winipcfg utility in Windows 98/ME to verify that your computer has received the correct address information from the Router. From the Start menu, choose Run and then enter winipcfg. Check that the computer has an IP address of the form 192.168.1.xxx (where xxx is in the range 2-254), the subnet mask is 255.255.255.0, and the default Router is 192.168.1.1 (the address of the Router). If these are not correct, use the Release and Renew functions to obtain a new IP address from the Router. Under Windows 2000 and Windows XP, use the ipconfig command-line utility to perform the same functions.Connecting to the InternetIf you can browse to the Router configuration screens but cannot access Web sites on the Internet, check the following:■Confirm that the physical connection between the Router and the telephone line is OK, and that the DSL LED on the Router is illuminated.■Ensure that you have entered the correct information into the Router configuration screens as required by your Internet Service Provider. Use the Internet Settings screen to verify this.■Check that the PPPoE or PPPoA user name and password are correct. ■Ensure that your computers are not configured to use a Web proxy. On Windows computers, this can be found under Control Panel > Internet Options > Connections.Forgotten Password and Reset to Factory DefaultsIf you can browse to the Router configuration screen but cannot log on because you do not know or have forgotten the password, follow the steps below to reset the Router to its factory default configuration. CAUTION: All your configuration changes will be lost, and you will need to run the configuration wizard again before you can re-establish your Router connection to the Internet. Also, other computer users will lose their network connections whilst this process is taking place, so choose a time when this would be convenient.1Power off the Router.2Disconnect all your computers and the telephone line from the Router.3Re-apply power to the Router, and wait for it to finish booting up.
Wireless Networking 1094Press and hold the Reset button on the rear panel (see Figure 4 on page 16) for 5 seconds.5The Router will restart, and when the start-up sequence has completed, browse to: http://192.168.1.1 and run the configuration wizard. You may need to restart your computer before you attempt this.6When the configuration wizard has completed, you may reconnect your network as it was before.Wireless Networking■Ensure that you have an 802.11b or 802.11g or 802.11n wireless adapter for each wireless computer, and that it is correctly installed and configured. Verify that each wireless computer has either Windows 98 or higher or MAC OS 8.5 or higher.■Verify that your wireless computers are configured to work in Infrastructure mode and not Ad Hoc mode. The Router contains an Access Point that is designed to operate in Infrastructure mode. Ad Hoc mode is not supported by the Router.■If you have a wired and a wireless NIC in the same computer, ensure that the wired NIC is disabled.■Check the status of the WLAN LED, it should be lit if wireless is enabled and will flash when there is wireless activity. If not lit go to Wireless Settings on page 49 and enable wireless networking.■Ensure that the TCP/IP settings for all devices are correct.■Ensure that the Wireless Clients are using the same SSID or Service Area Name as the Router. The SSID is case-sensitive.■Ensure that the encryption method and level that you use on your clients are the same as those configured on the Router. The Router cannot simultaneously support WPA and WEP encryption.■Ensure that you have the wireless computer enabled in the list of allowed MAC addresses if you are using MAC Address Filtering on the Router. ■If you are having difficulty connecting or are operating at a low speed try changing the antenna positions on the rear of the Router. For more effective coverage you can try reorientating your antennae. Place one antenna vertically and one horizontally to improve coverage.
110 CHAPTER 6: TROUBLESHOOTINGAdditionally consider moving the wireless computer closer to the Router to confirm that the building structure or fittings are not adversely affecting the connectivity. If this resolves the problem consider relocating the wireless computer or the Router, or trying a different channel on the Router.■Sources of interference: The 2.4Ghz ISM band is used for 802.11b and 802.11g. This is generally a licence free band for low power applications, and you may have other devices at your location that operate in this frequency band. You should take care to ensure that there are no devices, like microwave ovens for example, close to the Router or wireless computers as this could affect receiver sensitivity and reduce the performance of your network. If you are unsure try relocating both the wireless computers and the Router to establish whether this problem exists.■Most wireless computer adapters will scan the channels for the wireless Router. If a wireless computer has not located the Router then try initiating a search manually if the client software supports this feature or manually set the channel on your wireless computer to correspond to the Router channel number. Please refer to your wireless computer adapter documentation and vendor to do this.■Speed of connection: The 802.11b and 802.11g standards will automatically choose the best speed depending on the quality of your connection. As the signal quality weakens then the speed falls back to a lower speed. The speeds supported by 802.11g are 54 Mbps, 48 Mbps, 36 Mbps, 24 Mbps, 18 Mbps, 12 Mbps and 6 Mbps. The speeds supported by 802.11b are 11 Mbps, 5.5 Mbps, 2 Mbps and 1 Mbps. In general the closer you are to the Router the better the speed. If you are not achieving the speed you had anticipated then try moving the antenna on the Router or moving the wireless computer closer to the Router. In an ideal network the Router should be located in the centre of the network with wireless computers distributed around it. Applications are generally available with the computer wireless card to carry out a site survey. Use this application to find the optimal siting for your wireless computer. Consult your Computer Card documentation and vendor for more details.
Recovering from Corrupted Software 111Recovering from Corrupted SoftwareIf the system software has become corrupted, the Router will enter a “recovery” state; DHCP is enabled, and the LAN IP address is set to 192.168.1.1. Follow the instructions below to upload a new copy of the system software to a Router unit in this state.Ensure that one of your computers has a copy of the new software image file stored on its hard disk or available on CD-ROM.Check your ISP for the latest version firmware.1Remove power from the Router and disconnect the telephone line and all your computers, except for the one computer with the software image.2You will need to reconfigure this computer to obtain an IP address automatically (see Obtaining an IP Address Automatically on page 25).3Restart the computer, and re-apply power to the Router.4Using the Web browser on the computer, enter the following URL in the location bar: http://192.168.1.1. This will connect you to the Recovery utility in the Router.5Follow the on-screen instructions. Enter the path and filename of the software image file.6When the upload has completed, the Router will restart, run the self-test and, if successful, resume normal operation.7Refer to the Installation Guide to reconnect your Router to the telephone line and the computers in your network. Do not forget to reconfigure the computer you used for the software upload.If the Router does not resume normal operation following the upload, it may be faulty. Contact your supplier for advice.
112 CHAPTER 6: TROUBLESHOOTINGFrequently Asked Questions How do I reset the Router to Factory Defaults?See Forgotten Password and Reset to Factory Defaults on page 108.How many computers on the LAN does the Router support?A maximum of 253 computers on the LAN are supported.How many wireless clients does the Router support?A maximum of 128 wireless clients are supported.There are only 4 LAN ports on the Router. How are additional computers connected?You can expand the number of connections available on your LAN by using hubs, switches and wireless access points connected to the Router. 3Com wireless access points and hubs and switches provide a simple, reliable means of expanding your network; contact your supplier for more information, or visit:http://www.3com.com/Does the Router support virtual private networks (VPNs)?The Router supports VPN passthrough, which allows VPN clients on the LAN to communicate with VPN hosts on the Internet. It is also possible to set up VPN hosts on your LAN that clients elsewhere on the Internet can connect to, but this is not a recommended configuration.
AIP ADDRESSINGThe Internet Protocol SuiteThe Internet Protocol suite consists of a well-defined set of communications protocols and several standard application protocols. Transmission Control Protocol/Internet Protocol (TCP/IP) is probably the most widely known and is a combination of two of the protocols (IP and TCP) working together. TCP/IP is an internationally adopted and supported networking standard that provides connectivity between equipment from many vendors over a wide variety of networking technologies.Managing the Router over the NetworkTo manage a device over the network, the Router must be correctly configured with the following IP information:■An IP address■A Subnet MaskIP Addresses andSubnet MasksEach device on your network must have a unique IP address to operate correctly. An IP address identifies the address of the device to which data is being sent and the address of the destination network. IP addresses have the format n.n.n.x where n is a decimal number between 0 and 255 and x is a number between 1 and 254 inclusive.However, an IP address alone is not enough to make your device operate. In addition to the IP address, you need to set a subnet mask. All networks are divided into smaller sub-networks and a subnet mask is a number that enables a device to identify the sub-network to which it is connected.
114 APPENDIX A: IP ADDRESSINGFor your network to work correctly, all devices on the network must have:■The same sub-network address.■The same subnet mask.The only value that will be different is the specific host device number. This value must always be unique.An example IP address is ‘192.168.100.8’. However, the size of the network determines the structure of this IP address. In using the Router, you will probably only encounter two types of IP address and subnet mask structures.Type OneIn a small network, the IP address of ‘192.168.100.8’ is split into two parts:■Part one (‘192.168.100’) identifies the network on which the device resides.■Part two (‘.8’) identifies the device within the network.This type of IP address operates on a subnet mask of ‘255.255.255.0’.See Ta b l e 3 for an example about how a network with three computers and a Router might be configured.Tab le 3 IP Addressing and Subnet MaskingType TwoIn larger networks, where there are more devices, the IP address of ‘192.168.100.8’ is, again, split into two parts but is structured differently:■Part one (‘192.168’) identifies the network on which the device resides.■Part two (‘.100.8’) identifies the device within the network.Device IP Address Subnet MaskPC 1 192.168.100.8 255.255.255.0PC 2 192.168.100.33 255.255.255.0PC 3 192.168.100.188 255.255.255.0Router 192.168.100.72 255.255.255.0
How does a Device Obtain an IP Address and Subnet Mask? 115This type of IP Address operates on a subnet mask of ‘255.255.0.0’.See Ta b l e 4 for an example about how a network (only four computers represented) and a Router might be configured.Tab le 4 IP Addressing and Subnet MaskingHow does a Device Obtain an IP Address and Subnet Mask?There are three different ways to obtain an IP address and the subnet mask. These are:■Dynamic Host Configuration Protocol (DHCP) Addressing■Static Addressing■Automatic Addressing (Auto-IP Addressing)DHCP Addressing The Router contains a DHCP server, which allows computers on your network to obtain an IP address and subnet mask automatically. DHCP assigns a temporary IP address and subnet mask which gets reallocated once you disconnect from the network.DHCP will work on any client Operating System such as Windows 98, Windows NT 4.0, Windows 2000, Windows XP, and Windows Vista. Also, using DHCP means that the same IP address and subnet mask will never be duplicated for devices on the network. DHCP is particularly useful for networks with large numbers of users on them.Static Addressing You must enter an IP Address and the subnet mask manually on every device. Using a static IP and subnet mask means the address is permanently fixed.Auto-IP Addressing Network devices use automatic IP addressing if they are configured to acquire an address using DHCP but are unable to contact a DHCP server. Automatic IP addressing is a scheme where devices allocate themselves Device IP Address Subnet MaskPC 1 192.168.100.8 255.255.0.0PC 2 192.168.201.30 255.255.0.0PC 3 192.168.113.155 255.255.0.0PC 4 192.168.002.230 255.255.0.0Router 192.168.002.72 255.255.0.0
116 APPENDIX A: IP ADDRESSINGan IP address at random from the industry standard subnet of 169.254.x.x (with a subnet mask of 255.255.0.0). If two devices allocate themselves the same address, the conflict is detected and one of the devices allocates itself a new address. Automatic IP addressing support was introduced by Microsoft in the Windows 98 operating system and is also supported in Windows 2000 and Windows XP.

The rates will switch automatically depending on range and environment.10BASE-T The IEEE specification for 10 Mbps Ethernet over Category 3, 4 or 5 twisted pair cable.100BASE-TX The IEEE specification for 100 Mbps Fast Ethernet over Category 5 twisted-pair cable. Access Point An access point is a device through which wireless clients connect to other wireless clients and which acts as a bridge between wireless clients and a wired network, such as Ethernet. Wireless clients can be moved anywhere within the coverage area of the access point and still connect with each other. If connected to an Ethernet network, the access point monitors Ethernet traffic and forwards appropriate Ethernet messages to the wireless network, while also monitoring wireless client radio traffic and forwarding wireless client messages to the Ethernet LAN.Ad Hoc mode Ad Hoc mode is a configuration supported by most wireless clients. It is used to connect a peer to peer network together without the use of an access point. It offers lower performance than infrastructure mode, which is the mode the router uses. (see also Infrastructure mode.)
130 GLOSSARYAuto-negotiation Some devices in the range support auto-negotiation. Auto-negotiation is where two devices sharing a link, automatically configure to use the best common speed. The order of preference (best first) is: 100BASE-TX full duplex, 100BASE-TX half duplex, 10BASE-T full duplex, and 10BASE-T half duplex. Auto-negotiation is defined in the IEEE 802.3 standard for Ethernet and is an operation that takes place in a few milliseconds.Bandwidth The information capacity, measured in bits per second, that a channel can transmit. The bandwidth of Ethernet is 10 Mbps, the bandwidth of Fast Ethernet is 100 Mbps. The bandwidth for 802.11b wireless is 11Mbps.Category 3 Cables One of five grades of Twisted Pair (TP) cabling defined by the EIA/TIA-586 standard. Category 3 is voice grade cable and can only be used in Ethernet networks (10BASE-T) to transmit data at speeds of up to 10 Mbps. Category 5 Cables One of five grades of Twisted Pair (TP) cabling defined by the EIA/TIA-586 standard. Category 5 can be used in Ethernet (10BASE-T) and Fast Ethernet networks (100BASE-TX) and can transmit data up to speeds of 100 Mbps. Category 5 cabling is better to use for network cabling than Category 3, because it supports both Ethernet (10 Mbps) and Fast Ethernet (100 Mbps) speeds.Channel Similar to any radio device, the Wireless Cable/DSL router allows you to choose different radio channels in the wireless spectrum.

Some vendors of wireless products use SSID interchangeably with ESSID.Subnet Address An extension of the IP addressing scheme that allows a site to use a single IP network address for multiple physical networks. Subnet Mask A subnet mask, which may be a part of the TCP/IP information provided by your ISP, is a set of four numbers configured like an IP address. It is used to create IP address numbers used only within a particular network (as opposed to valid IP address numbers recognized by the Internet, which must assigned by InterNIC).Subnets A network that is a component of a larger network. Switch A device that interconnects several LANs to form a single logical LAN that comprises of several LAN segments. Switches are similar to bridges, in that they connect LANs of a different type; however they connect more LANs than a bridge and are generally more sophisticated.TCP/IP Transmission Control Protocol/Internet Protocol. This is the name for two of the most well-known protocols developed for the interconnection of networks. Originally a UNIX standard, TCP/IP is now supported on almost all platforms, and is the protocol of the Internet.TCP relates to the content of the data travelling through a network — ensuring that the information sent arrives in one piece when it reaches its destination. IP relates to the address of the end station to which data is being sent, as well as the address of the destination network.
