INTRODUCING THE ROUTER

Welcome to the world of networking with 3Com. In the modern business environment, communication and sharing information is crucial. Computer networks have proved to be one of the fastest modes of communication but, until recently, only large businesses could afford the networking advantage. The OfficeConnect product range from 3Com has changed all this, bringing networks to the small office. The products that compose the OfficeConnect range give you, the small office user, the same power, flexibility, and protection that has been available only to large corporations. Now, you can network the computers in your office, connect them all to a single Internet outlet, and harness the combined power of all of your computers.
OfficeConnect Wireless 54Mbps/108Mbps 11g cable/DSL Router
The OfficeConnect Wireless 54Mbps/108Mbps 11g cable/DSL Router is designed to provide a cost-effective means of sharing a single broadband Internet connection amongst several wired and wireless computers. The Router also provides protection in the form of an electronic firewall, preventing anyone outside of your network from seeing your files or damaging your computers. The Router can also prevent your users from accessing Web sites which you find unsuitable. Figure 1 shows an example network without a Router. In this network, only one computer is connected to the Internet. This computer must always be powered on for the other computers on the network to access the Internet.
CHAPTER 1: INTRODUCING THE ROUTER
Figure 1 Example Network Without a Router
When you use the Router in your network (Figure 2), it becomes your connection to the Internet. Connections can be made directly to the Router, or to an OfficeConnect Switch or Hub, expanding the number of computers you can have in your network.

A screen similar to Figure 8 should be displayed. 4 Select the Never Dial a Connection option.

LAN Settings

Figure 24 LAN IP Address Screen
This screen displays a suggested LAN IP address and subnet mask of the Router. It also allows you to change the IP address and subnet mask. DHCP The Router contains a Dynamic Host Configuration (DHCP) server that can automatically configure the TCP/IP settings of every computer on your network.
Figure 25 DHCP Server Setup Screen
To activate the DHCP Server option, select Enable the DHCP server with the following settings: and specify the IP pool range. The largest available continuous IP pool will be automatically entered; if this is not appropriate, make your required changes. To disable DHCP, select Do not enable the DHCP server. Click Next when you have finished.

Wireless Settings

Figure 26 Wireless Configuration Screen
This screen displays the Channel and Service Area Name. It also allows you to change these settings. There are a maximum of 14 channels, the number available to you is dependent on the country you reside in. Selecting Clear Channel Select from the Channel drop-down list allows the Router to automatically select an available channel when first powered on. The Service Area Name default for 3Com products is 3Com. Up to 32 (case sensitive) characters can be entered for the Service Area Name. 3Com strongly recommends that you change the SSID to something other than the default. Click Next when you have finished. If you are configuring the Router from a wireless computer any changes you make to the wireless configuration will result in communication between the Router and your computer being lost. This is why 3Com strongly recommends that you configure the Router from a wired computer. It is very important that you set up your wireless clients to use the same Service Area Name or SSID as the one you use on this screen. If your clients use a different Service Area Name then they will not be able to communicate with the Router. The choice of channel is less important as Clients will generally search all of the available channels. You should however make a note of the
channel you select as this may be useful if you experience problems with your clients. Summary
Figure 27 Configuration Summary Screen
When you complete the Setup Wizard, a configuration summary will display. 3Com recommends that you verify the configuration information of the Router and then print this page for your records. Click Finish to display the Wizard completed screen, shown in Figure 28
Figure 28 Wizard Completed Screen
If you have made changes to the LAN Settings or wireless configuration options, you may need to reconfigure the computer you are using in order to make contact with the Router again. Your Router is now configured and ready for use.
See Chapter 5 for a detailed description of the Router configuration screens.

Service Area Name/SSID This allows you to name your Wireless network. The Service Area Name/SSID field will accept any alphanumeric string and has a maximum length of 32 characters. Your Wireless computers must be configured with exactly the same name or you will not establish a connection. The Service Area Name may also be referred to as "ESSID" depending on your networking vendor. By default the Router uses the name "3Com". 3Com recommends that you change the default name. In order that your wireless computers can connect to the Router, you must:
Use Infrastructure Mode not Ad hoc Mode Have the same Service Area Name as the Router. Have the same Channel number as the Router. Use the same encryption type and keys as the Router. Ensure that the PC is included in the aouthorized Wireless PCs list if Connection Control is enabled.
Enable Broadcase SSID Disable this feature after you have installed your wireless network to improve the security of your network. When the check box is checked, the Router will broadcast the Service Area Name/SSID of your wireless network, whick reduces the security of your Router as it allows any wireless client to see your wireless LAN. If you have a wireless client that can detect all the available SSIDs in your area, your client will not list the Router SSID unless this feature is enabled. THe clients will still be able to connect, provided that they are supplied with the SSID. 3Com recommends that you install your wireless network with this feature enabled and than disable it once you have set up the Router and wireless clients. SSID If required, enter a name that you want to use to uniquely identify the device at the SSID prompt.

Encryption

When setting up wireless networks, it is important to remember that with encryption disabled, anyone with a Wireless PC can eavesdrop on your network. 3Com recommends that you get the network working with encryption disabled first and then enable it as the last step. This will simplify setting up your network. You can configure wireless security such as WEP or WPA encryption on this screen. Note: it is recommended that you use WPA encryption over WEP if your wireless clients support WPA All of the wireless clients must use the same security settings in order to connecdt to the router.

Dynamic IP Address

Figure 35 Connection Parameters Screen - Dynamic IP
If this mode is selected, your IP Address, Subnet Mask, and DNS Address will be obtained automatically from your ISP. They are not displayed on this screen, but may be viewed on the Status screen (click on Status and Logs on the left hand menu bar).

Firewall

On the main frame of the Firewall setup screen is a menu with six tabs: Virtual Servers, Special Applications, PCs Privileges, URL Filter, Content Filter and SPI. Selecting the Firewall option on the main menu displays the Virtual Servers setup screen. Virtual Servers Screen

Virtual Servers

Virtual DMZ
DMZ (De-Militarized Zone) Host is a computer without the protection of the firewall. This feature allows a single computer to be exposed to unrestricted 2-way communication from outside of your network. This feature should be used only if the Virtual Server or Special Applications options do not provide the level of access needed for certain applications. To configure one of your computers as a DMZ host, enter the last digit(s) of the IP address of the computer in the IP Address of DMZ Host text box, and then click Save.
Virtual Server Activating and configuring a virtual server allows one or more of the computers on your network to function as a public server. For example, one of your computers could be configured as an FTP server, allowing others outside of your office network to download files of your choosing. Or, if you have created a Web site, you can configure one of your computers as a Web server, so that others can view your Web site. If you want to host ftp server or online gaming, you must open up ports on the router. This page allows you to setup port forwarding for the specified applications. Before using forwarding, you should assian static IP addresses to the designated PCs. Click Save to save the settings.

Special Applications

Special Applications Screen
Select Special Apps tab to display Authorized Application setup screen. Some software applications require special or multiple connections to the Internet and these would normally be blocked by the firewall. For example Internet Telephony or Video conferences require multiple connections. So that these special applications can work properly and are not blocked, the firewall needs to be told about them. In each instance there will be a trigger port and incoming port(s), where traffic on the trigger port tells the firewall to open the incoming ports. Each defined Special Application only supports a single computer user, and up to 10 Special Applications can be defined. Any incoming ports opened by a Special Application trigger will be closed after five minutes of inactivity. Special Application allows the router to keep track of outgoing data for specific port numbers. The router remembers which computer sends out what data, so when the requested data returns through the router, the data is sent back to the proper computer by way of IP address and port mapping rules. Click Save to save the setting.

Only one computer on your network can use the special application at any one time. SPI Select Firewall from the main menu, then select the SPI to display the SPI screen. SPI Screen
Check the Enable SPI and Anti-Dos Firewall protection check box to enable SPI. When this feature is enabled, all incoming packets will be blocked except for those types that you allow in the Stateful Packet Inspection section. Web Filters:You can select to filter Proxy, Java, ActiveX, and/or Cookies. Click Save to save the setting.
QOS QoS(Quality of Service) manages information as it is transmitted and received. It ensures better service to those application with a higher priority.

Upgrade

Upgrade Screen
The Upgrade facility allows you to install on the Router any new releases of system software that 3Com may make available. To install new software, you first need to download the software from the 3Com support web site to a folder on your computer. Once you have done this, select Browse to tell your web browser where this file is on your computer, and then click Apply. The file will be copied to the Router, and once this has completed, the Router will restart. Although the upgrade process has been designed to preserve your configuration settings, it is recommended that you make a backup of the configuration beforehand, in case the upgrade process fails for any reason (for example, the connection between the computer and the Router is lost while the new software is being copied to the Router).

Advanced

The upgrade procedure can take up to two minutes, and is complete when the Alert LED has stopped flashing and is permanently off. Make sure that you do not interrupt power to the Router during the upgrade procedure; if you do, the software may be corrupted and the Router may not start up properly afterwards.
Selecting Advanced from the main menu displays the following five tabs in your Web browser window: Static Route, RIP, Security and Syslog. The Router supports static route functionality. Select the Static Route tab to display the screen Static Route screen

Static Route

The following information is displayed for each static route:
Index - the index of the static route Network Address - the network address of the route. If network address and subnet mask are both set to 0.0.0.0, this is the default route. Subnet Mask - the subnet mask of the route. If network address and subnet mask are both set to 0.0.0.0, this is the default route. Gateway - the gateway used to route data to the network specified by the network address.
The Router supports the Routing Information Protocol (RIP). RIP allows you to set up routing information on one RIP enabled device, and have that routing information replicated to all RIP enabled devices on the network. LAN and WAN interfaces can be configured independently of each other. Select the RIP tab to display the screen RIP screen

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.
How do I reset the Router to Factory Defaults? See Forgotten Password and Reset to Factory Defaults.
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 Cable/DSL 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 OfficeConnect hubs and switches provide a simple, reliable means of expanding your network; contact your supplier for more information, or visit:

Each 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.
APPENDIX B: IP ADDRESSING
For 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 One In 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 an example about how a network with three computers and a Router might be configured.
Table 4 IP Addressing and Subnet Masking
Device PC 1 PC 2 PC 3 Router IP Address 192.168.100.8 192.168.100.33 192.168.100.188 192.168.100.72 Subnet Mask 255.255.255.0 255.255.255.0 255.255.255.0 255.255.255.0
Type Two In 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.
How does a Device Obtain an IP Address and Subnet Mask?
This type of IP Address operates on a subnet mask of 255.255.0.0. See an example about how a network (only four computers represented) and a Router might be configured. IP Addressing and Subnet Masking
Device PC 1 PC 2 PC 3 PC 4 Router IP Address 192.168.100.8 192.168.201.30 192.168.113.155 192.168.002.230 192.168.002.72 Subnet Mask 255.255.0.0 255.255.0.0 255.255.0.0 255.255.0.0 255.255.0.0
There are three different ways to obtain an IP address and the subnet mask. These are:
