Using the Rubber

Feet

Use the four self-adhesive rubber feet to prevent your Router from moving around on your desk or when stacking with flat top units. Only stick the feet to the marked areas at each corner of the underside of your Router.

Please be careful when you put WL-603 on top of another unit, if the unit underneath is hot, this may impact the reliability of WL-603.

Wall Mounting There are two slots on the underside of the Router that can be used for

wall mounting. The Router must be mounted with the LEDs facing upwards.

When wall mounting the unit, ensure it is within reach of the power outlet. When wall mounting the unit, ensure that the rubber feet are not fixed.

Mounting

Instructions for

Cement Walls

To wall mount the unit:

1 Make two holes 100 mm (3.9 in.) apart and insert two nylon or similar

screw anchors that are suitable for the wall construction.

2 Fix two suitable screws into the anchors, leaving their heads 3 mm (0.12

in.) clear of the wall surface. The screws should be at least 30 mm (1.2 in.) long.

3 Remove any connections in the Router and locate it over the screw heads.

When in line, gently push the Router on to the wall and move it downwards to secure.

Mounting

Instructions for

Wood Walls

Powering Up the Router

To wall mount the unit:

1 Make two holes 100 mm (3.9 in.) apart. 2 Fix two suitable screws directly into the wall, leaving their heads 3 mm

(0.12 in.) clear of the wall surface. The screws should be at least 20 mm (0.75 in.) long.

3 Remove any connections in the Router and locate it over the screw heads.

When in line, gently push the Router on to the wall and move it downwards to secure.

CAUTION: When making connections, be careful not to push the unit up and off the wall.

To power up the Router:

1 Plug the power adapter into the power adapter socket located on the

back panel of the Router.

2 Plug the power adapter into a standard electrical wall socket.

Connecting the Router

The first step for installing your Router is to physically connect it to the telephone socket and then connect it to a computer in order to be able to access the Internet. See Figure 5:

22 CHAPTER 2: INSTALLING THE ROUTER

Figure 5 Connecting the Router

1 Run the provided telephone cable from the wall jack providing ADSL

service to the ADSL port on your Router. When inserting an ADSL RJ-11 plug, be sure the tab on the plug clicks into position to ensure that it is properly seated. If you are using splitterless ADSL service, add low-pass filters between the ADSL wall jack and your telephones. (These filters pass voice signals through but filter data signals out.)

2 Then:

■ If you are using a full-rate (G.dmt) connection, your service provider

will attach the outside ADSL line to a data/voice splitter. In this case you can connect your phones and computer directly to the splitter as shown below (Figure 6):

■ If you are using a splitterless (G.lite) connection, then your service

provider will attach the outside ADSL line directly to your phone system. In this case you can connect your phones and computer directly to the incoming ADSL line, but you will have to add low-pass filters to your phones as shown below (Figure 7)

RUNNING THE SETUP WIZARD

Accessing the Router using the 3Com Detect Application

Running the 3Com Detect Application

The 3Com Detect application works by automatically locating your Router, establishing what IP address it is using and then launching your default web browser to connect directly to it.

The application will only locate your Router if it is on the same subnet as the PC on which the application is running. It will not be able to locate your Router if there is another router between your PC and the Router. The application is only designed to run on Windows operating systems.

The CD-ROM that comes with this Router contains, in addition to the documentation, the 3Com Detect Application.

To use 3Com Detect to connect to the Web interface of your Router, do the following:

On the computer that is connected to your Router (either directly or on a network that is on the same subnet), insert the CD-ROM into its CD drive. If you have autorun enabled, you will be presented with a menu showing the contents of the CD-ROM. Select the 3Com Detect Application link to install the utility. Follow the onscreen instructions.

If the auto-run program does not start, you should browse to your CD-ROM drive, go to the /switch detect directory and double click on setup.exe. Follow the prompts that will take you through the installation process.

Once installed, the 3Com Detect Application can be accessed from the Windows Start/Programs list.

When the 3Com Detect application starts, you will see the Welcome Screen, see Figure 11.

32 CHAPTER 4: RUNNING THE SETUP WIZARD

Firewall 71

Firewall 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.

Special Applications Special Applications let you choose specific ports to be open for specific

applications to work properly with the Network Address Translation (NAT) feature of the Router.

Figure 60 Special Applications Screen

A list of popular applications has been included to choose from. Select the application from the Popular Applications drop-down menu. 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:

1 Specify 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.

2 Specify 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.

3 Check the Enabled checkbox, then click Apply.

76 CHAPTER 5: CONFIGURING THE ROUTER

Virtual 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 Screen

A 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.

If the server that you want to use is not listed in the drop-down menu, you can manually add the virtual server to the table. To manually configure your virtual servers:

1 Enter the IP address, and the description in the spaces provided for the

internal machine.

2 Select the protocol type (TCP, UDP, or both TCP and UDP) from the

drop-down menu.

Firewall 77

3 Specify the public port that will be seen by clients on the Internet, and the

LAN port which the traffic will be routed to.

4 You can enable or disable each Virtual Server entry by checking or

unchecking the appropriate Enabled checkbox.

5 Click Apply to save the changes for each Virtual Server entry.

DMZ If you have a client PC that cannot run an Internet application properly

from behind the firewall, you can open the client up to unrestricted two-way Internet access. This may be necessary if the NAT feature is causing problems with an application such as a game or video conferencing application.

Figure 62 DMZ Screen

Use this feature on a temporary basis. The computer in the DMZ is not protected from hacker attacks.

Check the Enable DMZ box, the IP Address of Virtual DMZ Host will appear.

1 Enter the last digits of the LAN IP address in the Client PC IP Address field.

Enter the IP address (if known) that will be accessing the DMZ PC into the Public IP Address field, so that only the computer on the Internet at this address can access the DMZ PC without firewall protection. If the IP address is not known, or if more than one PC on the Internet will need to access the DMZ PC, then set the Public IP Address to 0.0.0.0.

2 Click Apply.

78 CHAPTER 5: CONFIGURING THE ROUTER

PC Privileges The Router can be configured to restrict access to the Internet, email or

other network services at specific days and times. Restriction can be set for a single computer, a range of computers, or multiple computers.

You can define the traffic type permitted or not-permitted to the Internet.

82 CHAPTER 5: CONFIGURING THE ROUTER

Advanced 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 Settings

Security 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.

VLAN The VLAN screen allows you to setup VLAN groups.

Figure 69 VLAN Screen

Static Routes You can configure static routes in this screen.

Advanced 85

Figure 70 Static Routes Screen

To 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 ROUTER

Figure 71 Add Static Route Screen

Enter 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 87

RIP 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 Screen

You can set up RIP independently on both LAN and WAN interfaces.

1 Check the Enable RIP checkbox. 2 Check the Enable Auto summary checkbox. Auto summarization sends

simplified routing data to other RIP-enabled devices rather than full routing data.

3 Select 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.

4 In 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 ROUTER

5 Use 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.

6 Use 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.

7 In the Password field, enter the required password. 8 Click Apply.

Advanced 89

DDNS 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.com

Figure 73 Dynamic Domain Name Server (DDNS) Screen

1 Check Enable DDNS. 2 Select the provider, and then enter the necessary information provided by

your DDNS provider.

3 Click Apply.

90 CHAPTER 5: CONFIGURING THE ROUTER

SNMP 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 Screen

To Configure SNMP Community:

1 In 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.

2 In 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.

3 Check the appropriate Valid checkbox to enable the communication

channel.

Advanced 91

You can configure your Router to send status messages to the SNMP management agent if a problem occurs on the network. To configure SNMP traps:

1 In the IP Address field, enter the IP address of the PC to which you want

your Router to send status messages.

2 In the Community field, enter the name of the SNMP communication

channel to which you want your Router to send status messages.

3 Set 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 Screen

1 Check the Enable Syslog Server checkbox. 2 Enter the Server LAN IP Address in the space provided. 3 Click Apply.

92 CHAPTER 5: CONFIGURING THE ROUTER

Proxy 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 Screen

1 Check the Enable ProxyARP box. 2 Enter the corresponding IP address in the IP Address From and IP Address

To fields.
