Wireless LAN Networking

This section provides background information on wireless LAN networking technology. Consult

the Glossary for definitions of the terminology used in this section.

THE INFORMATION IN THIS SECTION IS FOR YOUR REFERENCE. CHANGING

NETWORK SETTINGS AND PARTICULARLY SECURITY SETTTINGS SHOULD ONLY

BE DONE BY AN AUTHORIZED ADMINISTRATOR.

Transmission Rate (Transfer Rate)

The SMCWBR14-N2 provides various transmission (data) rate options for you to select. In most

networking scenarios, the factory default Best (automatic) setting proves the most efficient. This

setting allows your SMCWBR14-N2 to operate at the maximum transmission (data) rate. When the

communication quality drops below a certain level, the SMCWBR14-N2 automatically switches to

a lower transmission (data) rate. Transmission at lower data speeds is usually more reliable.

However, when the communication quality improves again, the SMCWBR14-N2 gradually

increases the transmission (data) rate again until it reaches the highest available transmission

rate.

Types of Wireless Networks

Wireless LAN networking works in either of the two modes: ad-hoc and infrastructure. In infra-

structure mode, wireless devices communicate to a wired LAN via access points. Each access

point and its wireless devices are known as a Basic Service Set (BSS). An Extended Service Set

(ESS) is two or more BSSs in the same subnet. In ad hoc mode (also known as peer-to-peer

mode), wireless devices communicate with each other directly and do not use an access point.

This is an Independent BSS (IBSS).

To connect to a wired network within a coverage area using access points, set the operation mode

to Infrastructure (BSS). To set up an independent wireless workgroup without an access point, use

Ad-hoc (IBSS) mode.

AD-HOC (IBSS) NETWORK

Ad-hoc mode does not require an access point or a wired network. Two or more wireless stations

communicate directly to each other. An ad-hoc network may sometimes be referred to as an

Independent Basic Service Set (IBSS).

To set up an ad-hoc network, configure all the stations in ad-hoc mode. Use the same SSID and

channel for each station.

When a number of wireless stations are connected using a single access point, you have a Basic

Service Set (BSS).

In the ESS diagram below, communication is done through the access points, which relay data

packets to other wireless stations or devices connected to the wired network. Wireless stations

can then access resources, such as a printer, on the wired network.

In an ESS environment, users are able to move from one access point to another without losing the

connection. In the diagram below, when the user moves from BSS (1) to BSS (2) the WLAN client

devices automatically switches to the channel used in BSS (2).

Introduction

The SMCWBR14-N2 is a high-performance, wireless router that supports high-speed wireless

networking at home, at work or in public places.

Unlike most routers, the SMCWBR14-N2 provides data transfers at up to 300Mbps when using 11n

(Draft) connection. This router is also backwards compatible with 802.11g or 11b devices. This means

that you do not need to change your entire network to maintain connectivity. You may sacrifice some

of 11n’s (Draft) speed when you mix 11n (Draft) and 11b/g devices, but you will not lose the ability to

communicate when you incorporate the 11n (Draft) standard into your 11b/g network. You may

choose to slowly change your network by gradually replacing the 11b/g devices with 11n (Draft)

devices.

Installation Considerations

The SMCWBR14-N2 lets you access your network, using a wireless connection, from virtually

anywhere within its operating range. Keep in mind, however, that the number, thickness and location

of walls, ceilings, or other objects that the wireless signals must pass through, may limit the range.

Typical ranges vary depending on the types of materials and background RF (radio frequency) noise

in your home or business. The key to maximizing wireless range is to follow these basic guidelines:

1 Keep the number of walls and ceilings between the SMCWBR14-N2 and other network

devices to a minimum - each wall or ceiling can reduce your wireless product’s range from

3-90 feet (1-30 meters.) Position your devices so that the number of walls or ceilings is

minimized.

2 Be aware of the direct line between network devices. A wall that is 1.5 feet thick (.5 meters), at

a 45-degree angle appears to be almost 3 feet (1 meter) thick. At a 2-degree angle it looks

over 42 feet (14 meters) thick! Position devices so that the signal will travel straight through a

wall or ceiling (instead of at an angle) for better reception.

3 Building Materials can impede the wireless signal - a solid metal door or aluminum studs may

have a negative effect on range. Try to position wireless devices and computers with wireless

adapters so that the signal passes through drywall or open doorways and not other materials.

4 Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices or appliances

that generate extreme RF noise.

Getting Started

For a typical home setup, you will need a Broadband (Cable/xDSL) Internet service and Modem

with Ethernet connection. Consult with your Cable or xDSL provider for proper installation of the

modem. Please do the following:

1. Connect your Broadband modem (Cable/xDSL) to the blue WAN port on the Barricade™

2. Connect the network card of your PC to the yellow LAN port on the Barricade™ using the

yellow RJ-45 cable provided. Now connect the power adapter.

3. Reboot PC. Start web browser and enter address http://192.168.2.1. When prompted enter

password smcadmin then click [Log In]. Note: The User Name must be set to Admin.

4. Click [BASIC], then [Setup Wizard], then [Launch Internet Connection Setup Wizard]. Follow

the on screen instructions to complete the set-up and reboot the Barricade™. You are now

ready to enjoy your Internet connection.

Using the Configuration Menu

Whenever you want to configure your SMCWBR14-N2, you can access the Configuration Menu

through your PC by opening the Web-browser and typing in the IP Address of the SMCWBR14-N2.

The SMCWBR14-N2 default IP address is: http://192.168.2.1

¾ Open the Web browser.

¾ Type in the IP Address of the Router (http://192.168.2.1).

If you have changed the default IP Address assigned to the SMCWBR14-N2, make sure

you enter the correct IP Address.

¾ Select Admin in the User Name field.

¾ Enter Password: smcadmin (default).

¾ Click Log In.

If you have changed the default password assigned to the SMCWBR14-N2, make sure you

enter the correct password.

Basic

The Basic tab provides the following configuration options: INTERNET, WIRELESS and NETWORK

SETTINGS.

Basic_Internet

Setup Wizard

If you are new to networking and have never configured a router before, click on Setup Wizard

and the router will guide you through a few simple steps to get your network up and running.

Manual Configure

If you consider yourself an advanced user and have configured a router before, click Manual

Configure to input all the settings manually.

Basic_Wireless

The wireless section is used to configure the wireless settings for your router. Note that changes made

in this section may also need to be duplicated on wireless clients that you want to connect to your

wireless network.

To protect your privacy, use the wireless security mode to configure the wireless security features. This

device supports three wireless security modes including: WEP, WPA-Personal, and WPA-Enterprise.

WEP is the original wireless encryption standard. WPA-Enterprise provides a higher level of security.

WPA-Personal does not require an authentication server. The WPA-Enterprise option requires a

RADIUS authentication server.

Enable Wireless

This option allows you to enable/disable the wireless AP function. The wireless can also be

turned ON/OFF by the slide switch on the back panel. When the wireless is enabled, the

following parameters are in effect.

Wireless Network Name

When you are browsing for available wireless networks, this is the name that will appear in the

list (unless Visibility Status is set to Invisible, see below). This name is also referred to as the

SSID. For security purposes, it is highly recommended to change from the pre-configured

network name.

Enable Auto Channel Scan

If you select this option, the router automatically finds the channel with least interference and

uses that channel for wireless networking. If you disable this option, the router uses the

channel that you specify with the following Wireless Channel option.

Wireless Channel

A wireless network uses specific channels in the wireless spectrum to handle communication

between clients. Some channels in your area may have interference from other electronic

devices. Choose the clearest channel to help optimize the performance and coverage of your

wireless network.

802.11 Mode

If all of the wireless devices you want to connect with this router can connect in the same

transmission mode, you can improve performance slightly by choosing the appropriate "Only"

mode. If you have some devices that use a different transmission mode, choose the

appropriate "Mixed" mode.

Channel Width

The "Auto 20/40 MHz" option is usually best. The other options are available for special

circumstances. Note that when 20/40MHz option is selected, an extended channel will be used

to extend the data rate.

Transmission Rate

By default the fastest possible transmission rate will be selected. You have the option of

selecting the speed if necessary.

Visibility Status

The Invisible option allows you to hide your wireless network. When this option is set to Visible,

your wireless network name is broadcast to anyone within the range of your signal. If you're not

using encryption then they could connect to your network. When Invisible mode is enabled,

you must enter the Wireless Network Name (SSID) on the client manually to connect to the

network.

Security Mode (NONE, WEP, WPA-Personal, WPA-Enterprise)

Unless one of these encryption modes is selected, wireless transmissions to and from your

wireless network can be easily intercepted and interpreted by unauthorized users.

WEP

A method of encrypting data for wireless communication intended to provide the same level of

privacy as a wired network. WEP is not as secure as WPA encryption. To gain access to a

WEP network, you must know the key. The key is a string of characters that you create. When

using WEP, you must determine the level of encryption. The type of encryption determines the

key length. 128-bit encryption requires a longer key than 64-bit encryption. Keys are defined by

entering in a string in HEX (hexadecimal - using characters 0-9, A-F) or ASCII (American

Standard Code for Information Interchange - alphanumeric characters) format. ASCII format is

provided so you can enter a string that is easier to remember. The ASCII string is converted to

HEX for use over the network. Four keys can be defined so that you can change keys easily. A

default key is selected for use on the network.

Example:

64-bit hexadecimal keys are exactly 10 characters in length. (12345678FA is a valid string

of 10 characters for 64-bit encryption.)

128-bit hexadecimal keys are exactly 26 characters in length.

(456FBCDF123400122225271730 is a valid string of 26 characters for 128-bit

encryption.)

64-bit ASCII keys are up to 5 characters in length (DMODE is a valid string of 5

characters for 64-bit encryption.)

128-bit ASCII keys are up to 13 characters in length (2002HALOSWIN1 is a valid string of

13 characters for 128-bit encryption.)

Note that, if you enter fewer characters in the WEP key than required, the remainder of the key

is automatically padded with zeros.

WPA-Personal and WPA-Enterprise

Both of these options select some variant of Wi-Fi Protected Access (WPA) -- security

standards published by the Wi-Fi Alliance. The WPA Mode further refines the variant that the

router should employ.

WPA Mode: WPA is the older standard; select this option if the clients that will be used with

the router only support the older standard. WPA2 is the newer implementation of the stronger

IEEE 802.11i security standard. With the "WPA or WPA2" option, the router tries WPA2 first,

but falls back to WPA if the client only supports WPA. The strongest cipher that the client

supports will be used. With the "WPA2 Only" option, the router associates only with clients that

also support WPA2 security. If the clients support the AES cipher, it will be used across the

wireless network to ensure best security.

Group Key Update Interval: The amount of time before the group key used for broadcast and

multicast data is changed.

WPA-Personal

This option uses Wi-Fi Protected Access with a Pre-Shared Key (PSK).

Pre-Shared Key: The key is entered as a pass-phrase of up to 63 alphanumeric characters in

ASCII (American Standard Code for Information Interchange) format at both ends of the

wireless connection. It cannot be shorter than eight characters, although for proper security it

needs to be of ample length and should not be a commonly known phrase. This phrase is used

to generate session keys that are unique for each wireless client.

Example:

Wireless Networking technology enables ubiquitous communication

WPA-Enterprise

This option works with a RADIUS Server to authenticate wireless clients. Wireless clients

should have established the necessary credentials before attempting to authenticate to the

Server through this Gateway. Furthermore, it may be necessary to configure the RADIUS

Server to allow this Gateway to authenticate users.

Authentication Timeout: Amount of time before a client will be required to re-authenticate.

RADIUS Server IP Address: The IP address of the authentication server.

RADIUS Server Port: The port number used to connect to the authentication server.

RADIUS Server Shared Secret: A pass-phrase that must match with the authentication

server.

MAC Address Authentication: If this is selected, the user must connect from the same

computer whenever logging into the wireless network.

Advanced:

Optional Backup RADIUS Server

This option enables configuration of an optional second RADIUS server. A second

RADIUS server can be used as backup for the primary RADIUS server. The second

RADIUS server is consulted only when the primary server is not available or not

responding. The fields Second RADIUS Server IP Address, RADIUS Server Port,

Second RADIUS server Shared Secret, Second MAC Address Authentication provide

the corresponding parameters for the second RADIUS Server.

Basic_Network Settings

Use this section to configure the internal network settings of your router. The IP Address that is

configured here is the IP Address that you use to access the Web-based management interface. If

you change the IP Address here, you may need to adjust your PC’s network settings to access the

network again.

Router Settings

These are the settings of the LAN (Local Area Network) interface for the router. The router's

local network (LAN) settings are configured based on the IP Address and Subnet Mask

assigned in this section. The IP address is also used to access this Web-based management

interface. It is recommended that you use the default settings if you do not have an existing

network.

IP Address

The IP address of your router on the local area network. Your local area network settings

are based on the address assigned here. For example, 192.168.2.1.

Subnet Mask

The subnet mask of your router on the local area network.

Local Domain Name

This entry is optional. Enter a domain name for the local network. The router's DHCP

server will give this domain name to the computers on the wireless LAN. So, for example,

if you enter mynetwork.net here, and you have a wireless laptop with a name of chris,

that laptop will be known as chris.mynetwork.net. Note, however, if the router's settings

specify "DHCP (Dynamic)" Address, and the router's DHCP server assigns a domain

name to the AP, that domain name will override any name you enter here.

DNS Relay

When DNS Relay is enabled, the router plays the role of a DNS server. DNS requests

sent to the router are forwarded to the ISP's DNS server. This provides a constant DNS

address that LAN computers can use, even when the router obtains a different DNS

server address from the ISP upon re-establishing the WAN connection. You should

disable DNS relay if you implement a LAN-side DNS server as a virtual server.

RIP (Routing Information Protocol)

Used to broadcast routing information among routers.

Enable RIP

Enable RIP if required by the ISP, if the LAN has multiple routers, or if the LAN has

auto-IP devices.

RIP Operating mode

This router supports both version 2 and version 1 of the RIP specification.

V1. Use if none of the routers supports Version 2.

V2 Broadcast. Use if some routers are capable of Version 2, but some are only capable

of Version 1.

V2 Multicast. Use if this is the only router on the LAN or if all the routers support Version

Router Metric

The additional cost of routing a packet through this router. The normal value for a simple

network is 1. This metric is added to routes learned from other routers; it is not added to

static or system routes.

Act as default router

Make this router the preferred destination for packets that are not otherwise destined.

Allow RIP updates from WAN

For security, disable this option unless required by the ISP.

RIP Password

RIP Version 2 supports the use of a password to limit access to routers through the RIP

protocol. If the ISP or other LAN router requires a RIP password, enter the password here.

DHCP Server Settings

DHCP stands for Dynamic Host Configuration Protocol. The DHCP section is where you

configure the built-in DHCP Server to assign IP addresses to the computers and other devices

on your local area network (LAN).

Enable DHCP Server

Once your router is properly configured and this option is enabled, the DHCP Server will

manage the IP addresses and other network configuration information for computers and

other devices connected to your Local Area Network. There is no need for you to do this

yourself.

The computers (and other devices) connected to your LAN also need to have their TCP/IP

configuration set to "DHCP" or "Obtain an IP address automatically".

When you set Enable DHCP Server, the following options are displayed.

DHCP IP Address Range

These two IP values (from and to) define a range of IP addresses that the DHCP Server

uses when assigning addresses to computers and devices on your Local Area Network.

Any addresses that are outside of this range are not managed by the DHCP Server; these

could, therefore, be used for manually configured devices or devices that cannot use

DHCP to obtain network address details automatically.

It is possible for a computer or device that is manually configured to have an address that

does reside within this range. In this case the address should be reserved (see Static

DHCP Client below), so that the DHCP Server knows that this specific address can only

be used by a specific computer or device.

Your router, by default, has a static IP address of 192.168.2.1. This means that addresses

192.168.2.2 to 192.168.2.254 can be made available for allocation by the DHCP Server.

Example:

Your router uses 192.168.2.1 for the IP address. You've assigned a computer that you

want to designate as a Web server with a static IP address of 192.168.2.3. You've

assigned another computer that you want to designate as an FTP server with a static IP

address of 192.168.2.4. Therefore the starting IP address for your DHCP IP address

range needs to be 192.168.2.5 or greater.

Example:

Suppose you configure the DHCP Server to manage addresses From: 192.168.2.100

To: 192.168.2.199. This means that 192.168.2.3 to 192.168.2.99 and 192.168.2.200 to

192.168.2.254 are NOT managed by the DHCP Server. Computers or devices that use

addresses from these ranges are to be manually configured. Suppose you have a web

server computer that has a manually configured address of 192.168.2.100. Because

this falls within the "managed range" be sure to create a reservation for this address

and match it to the relevant computer (see Static DHCP Client below).

DHCP Lease Time

The amount of time that a computer may have an IP address before it is required to renew

the lease. The lease functions just as a lease on an apartment would. The initial lease

designates the amount of time before the lease expires. If the tenant wishes to retain the

address when the lease is expired then a new lease is established. If the lease expires

and the address is no longer needed than another tenant may use the address.

Always Broadcast

If all the computers on the LAN successfully obtain their IP addresses from the router's

DHCP server as expected, this option can remain disabled. However, if one of the

computers on the LAN fails to obtain an IP address from the router's DHCP server, it may

have an old DHCP client that incorrectly turns off the broadcast flag of DHCP packets.

Enabling this option will cause the router to always broadcast its responses to all clients,

thereby working around the problem, at the cost of increased broadcast traffic on the LAN.

Add/Edit DHCP Reservation

This option lets you reserve IP addresses, and assign the same IP address to the network

device with the specified MAC address any time it requests an IP address. This is almost the

same as when a device has a static IP address except that the device must still request an IP

address from the router. The router will provide the device the same IP address every time.

DHCP Reservations are helpful for server computers on the local network that are hosting

applications such as Web and FTP. Servers on your network should either use a static IP

address or use this option.

Computer Name

You can assign a name for each computer that is given a reserved IP address. This may

help you keep track of which computers are assigned this way. Example: Game Server.

IP Address:

The LAN address that you want to reserve.

MAC Address

To input the MAC address of your system, enter it in manually or connect to the router's

Web-Management interface from the system and click the Copy Your PC’s MAC

Address button.

A MAC address is usually located on a sticker on the bottom of a network device. The

MAC address is comprised of twelve digits. Each pair of hexadecimal digits are usually

separated by dashes or colons such as 00-0D-88-11-22-33 or 00:0D:88:11:22:33. If your

network device is a computer and the network card is already located inside the computer,

you can connect to the router from the computer and click the Copy Your PC’s MAC

Address button to enter the MAC address.

As an alternative, you can locate a MAC address in a specific operating system by

following the steps below:

Windows 98

Windows Me

Go to the Start menu, select Run, type in winipcfg, and hit Enter. A

popup window will be displayed. Select the appropriate adapter from the

pull-down menu and you will see the Adapter Address. This is the MAC

address of the device.

Windows 2000

Windows XP

Go to your Start menu, select Programs, select Accessories, and select

Command Prompt. At the command prompt type ipconfig /all and hit

Enter. The physical address displayed for the adapter connecting to the

router is the MAC address.

Mac OS X Go to the Apple Menu, select System Preferences, select Network, and

select the Ethernet Adapter connecting to the router. Select the Ethernet

button and the Ethernet ID will be listed. This is the same as the MAC

address.

DHCP Reservations List

This shows clients that you have specified to have reserved DHCP addresses. An entry can be

changed by clicking the Edit icon, or deleted by clicking the Delete icon. When you click the

Edit icon, the item is highlighted, and the "Edit DHCP Reservation" section is activated for

editing.

Number of Dynamic DHCP Clients

In this section you can see what LAN devices are currently leasing IP addresses.

Revoke

The Revoke option is available for the situation in which the lease table becomes full or

nearly full, you need to recover space in the table for new entries, and you know that

some of the currently allocated leases are no longer needed. Clicking Revoke cancels the

lease for a specific LAN device and frees an entry in the lease table. Do this only if the

device no longer needs the leased IP address, because, for example, it has been

removed from the network.

Reserve

The Reserve option converts this dynamic IP allocation into a DHCP Reservation and

adds the corresponding entry to the DHCP Reservations List.

Advanced

The Advanced tab provides the following configuration options: Virtual Server, Special Applications,

Gaming, StreamEngine, Routing, Access Control, WEB Filter, MAC Address Filter, Firewall,

Inbound Filter, Advanced Wireless and Advanced Network.

Advanced_Virtual Server

The Virtual Server option gives Internet users access to services on your LAN. This feature is useful

for hosting online services such as FTP, Web, or game servers. For each Virtual Server, you define a

public port on your router for redirection to an internal LAN IP Address and LAN port.

Example:

You are hosting a Web Server on a PC that has LAN IP Address of 192.168.2.50 and your ISP

is blocking Port 80.

1. Name the Virtual Server (for example: Web Server)

2. Enter the IP Address of the machine on your LAN (for example: 192.168.2.50

3. Enter the Private Port as [80]

4. Enter the Public Port as [8888]

5. Select the Protocol (for example TCP).

6. Ensure the schedule is set to Always

7. Click Save to add the settings to the Virtual Servers List

8. Repeat these steps for each Virtual Server Rule you wish to add. After the list is

complete, click Save Settings at the top of the page.

With this Virtual Server entry, all Internet traffic on Port 8888 will be redirected to your internal

web server on port 80 at IP Address 192.168.2.50.

Virtual Server Parameters

Name

Assign a meaningful name to the virtual server, for example Web Server. Several

well-known types of virtual server are available from the "Application Name" drop-down

list. Selecting one of these entries fills some of the remaining parameters with standard

values for that type of server.

IP Address

The IP address of the system on your internal network that will provide the virtual service,

for example 192.168.2.50. You can select a computer from the list of DHCP clients in the

"Computer Name" drop-down menu, or you can manually enter the IP address of the

server computer.

Protocol

Select the protocol used by the service. The common choices -- UDP, TCP, and both UDP

and TCP -- can be selected from the drop-down menu. To specify any other protocol,

select "Other" from the list, then enter the corresponding protocol number ( as assigned

by the IANA) in the Protocol box.

Private Port

The port that will be used on your internal network.

Public Port

The port that will be accessed from the Internet.

Inbound Filter

Select a filter that controls access as needed for this virtual server. If you do not see the

filter you need in the list of filters, go to the Advanced → Inbound Filter screen and create

a new filter.

Schedule

Select a schedule for when the service will be enabled. If you do not see the schedule you

need in the list of schedules, go to the Tools → Schedules screen and create a new

schedule.

Add/Edit Virtual Server

In this section you can add an entry to the Virtual Servers List below or edit an existing entry.

Enable

Entries in the list can be either active (enabled) or inactive (disabled).

Save

Saves the new or edited virtual server entry in the following list. When finished updating

the virtual server entries, you must still click the Save Settings button at the top of the

page to make the changes effective and permanent.

Virtual Servers List

The section shows the currently defined virtual servers. A Virtual Server can be changed by

clicking the Edit icon, or deleted by clicking the Delete icon. When you click the Edit icon, the

item is highlighted, and the "Edit Virtual Server" section is activated for editing.

You might have trouble accessing a virtual server using its public identity (WAN-side

IP-address of the gateway or its dynamic DNS name) from a machine on the LAN. Your

requests may not be looped back or you may be redirected to the "Forbidden" page.

This will happen if you have an Access Control Rule configured for this LAN machine.

The requests from the LAN machine will not be looped back if Internet access is blocked at the time of

access. To work around this problem, access the LAN machine using its LAN-side identity.

Requests may be redirected to the "Forbidden" page if web access for the LAN machine is restricted

by an Access Control Rule. Add the WAN-side identity (WAN-side IP-address of the router or its

dynamic DNS name) on the Advanced → Web Filter screen to work around this problem.

Advanced_Special Applications

An application rule is used to open single or multiple ports on your router when the router senses data

sent to the Internet on a "trigger" port or port range. An application rule applies to all computers on

your internal network.

Parameters for an Application Rule

Example:

You need to configure your router to allow a software application running on any computer

on your network to connect to a web-based server or another user on the Internet.

Name

Enter a name for the Special Application Rule, for example Game App, which will help

you identify the rule in the future. Alternatively, you can select from the Application list of

common applications.

Application

Instead of entering a name for the Special Application rule, you can select from this list of

common applications, and the remaining configuration values will be filled in accordingly.

Trigger Port Range

Enter the outgoing port range used by your application (for example 6500-6700).

Trigger Protocol

Select the outbound protocol used by your application (for example Both).

Input Port Range

Enter the port range that you want to open up to Internet traffic (for example 6000-6200).

Input Protocol

Select the protocol used by the Internet traffic coming back into the router through the

opened port range (for example Both).

Schedule

Select a schedule for when this rule is in effect. If you do not see the schedule you need

in the list of schedules, go to the Tool s → Schedules screen and create a new schedule.

With the above example application rule enabled, the router will open up a range of ports from

6000-6200 for incoming traffic from the Internet, whenever any computer on the internal

network opens up an application that sends data to the Internet using a port in the range of

6500-6700.

Add/Edit Special Applications Rule

This section is where you define and edit Special Applications Rules.

Save

Saves the new or edited Special Applications Rule in the following list. When finished

updating the special applications rules, you must still click the Save Settings button at the

top of the page to make the changes effective and permanent.

Special Applications Rules List

The section shows the currently defined special applications rules. A special applications rule

can be changed by clicking the Edit icon, or deleted by clicking the Delete icon. When you click

the Edit icon, the item is highlighted, and the "Edit Special Applications Rule" section is

activated for editing.

Advanced_Gaming

Multiple connections are required by some applications, such as internet games, video conferencing,

Internet telephony, and others. These applications have difficulties working through NAT (Network

Address Translation). This section is used to open multiple ports or a range of ports in your router and

redirect data through those ports to a single PC on your network. You can enter ports in various

formats:

Range (50-100)

Individual (80, 68, 888)

Mixed (1020-5000, 689)

Example:

Suppose you are hosting an online game server that is running on a PC with a private IP

Address of 192.168.2.50. This game requires that you open multiple ports (6159-6180, 99) on

the router so Internet users can connect.

Port Forwarding Fields

Name

Give the rule a name that is meaningful to you, for example Game Server. You can also select

from a list of popular games, and many of the remaining configuration values will be filled in

accordingly. However, you should check whether the port values have changed since this list

was created, and you must fill in the IP address field.

IP Address

Enter the local network IP address of the system hosting the server, for example 192.168.2.50.

TCP Ports To Open

Enter the TCP ports to open (for example 6159-6180, 99).

UDP Ports To Open

Enter the UDP ports to open (for example 6159-6180, 99).

Inbound Filter

Select a filter that controls access as needed for this rule. If you do not see the filter you need

in the list of filters, go to the Advanced → Inbound Filter screen and create a new filter.

Schedule

Select a schedule for the times when this rule is in effect. If you do not see the schedule you

need in the list of schedules, go to the Tools → Schedules screen and create a new schedule.

With the above example values filled in and this Gaming Rule enabled, all TCP and UDP traffic

on ports 6159 through 6180 and port 99 is passed through the router and redirected to the

Internal Private IP Address of your Game Server at 192.168.2.50.

Edit/Add Game Rule

Here you can add entries to the Game Rules List below, or edit existing entries.

Enable

Each entry in Game Rules List can be active (enabled) or inactive (disabled)

Save

Saves the new or edited Game Rule in the following list. When finished updating the game

rules, you must still click the Save Settings button at the top of the page to make the changes

effective and permanent.

Game Rules List

The section shows the currently defined game rules. A game rule can be changed by clicking

the Edit icon, or deleted by clicking the Delete icon. When you click the Edit icon, the item is

highlighted, and the "Edit Game Rule" section is activated for editing.

Advanced_StreamEngine

The StreamEngine feature helps improve your network gaming performance by prioritizing the data

flows of network applications.

StreamEngine Setup

Enable StreamEngine

Enable this option for better performance and experience with online games and other

interactive applications, such as VoIP.

Automatic Classification

This option is enabled by default so that your router will automatically determine which

programs should have network priority.

Dynamic Fragmentation

This option should be enabled when you have a slow Internet uplink. It helps to reduce

the impact that large low priority network packets can have on more urgent ones by

breaking the large packets into several smaller packets.

Automatic Uplink Speed

When enabled, this option causes the router to automatically measure the useful uplink

bandwidth each time the WAN interface is re-established (after a reboot, for example).

Measured Uplink Speed

This is the uplink speed measured when the WAN interface was last re-established. The

value may be lower than that reported by your ISP as it does not include all of the network

protocol overheads associated with your ISP's network. Typically, this figure will be

between 87% and 91% of the stated uplink speed for xDSL connections and around 5

kbps lower for cable network connections.

Manual Uplink Speed

If Automatic Uplink Speed is disabled, this options allows you to set the uplink speed

manually. Uplink speed is the speed at which data can be transferred from the router to

your ISP. This is determined by your ISP. ISPs often specify speed as a downlink/uplink

pair; for example, 1.5Mbps/284kbps. For this example, you would enter "284".

Alternatively you can test your uplink speed with a service such as www.dslreports.com.

Note however that sites such as DSL Reports, because they do not consider as many

network protocol overheads, will generally note speeds slightly lower than the Measured

Uplink Speed or the ISP rated speed.

Connection Type

By default, the router automatically determines whether the underlying connection is an

xDSL/Frame-relay network or some other connection type (such as cable modem or

Ethernet), and it displays the result as Detected xDSL or Frame Relay Network. If you

have an unusual network connection in which you are actually connected via xDSL but for

which you configure either "Static" or "DHCP" in the WAN settings, setting this option to

xDSL or Other Frame Relay Network ensures that the router will recognize that it needs

to shape traffic slightly differently in order to give the best performance. Choosing xDSL

or Other Frame Relay Network causes the measured uplink speed to be reported

slightly lower than before on such connections, but gives much better results.

Detected xDSL or Frame Relay Network

When Connection Type is set to Auto-detect, the automatically detected connection

type is displayed here.

StreamEngine Rules

A StreamEngine Rule identifies a specific message flow and assigns a priority to that flow. For

most applications, automatic classification will be adequate, and specific StreamEngine Rules

will not be required.

Conflicting rules are not permitted. Conflicting rules are those that share any combination of

source address/port, destination address/port, and protocol. Rejecting conflicting rules ensures

that every flow defined in a rule receives the expected priority and avoids indeterminate

prioritization that could reduce QoS effectiveness.

Name

Create a name for the rule that is meaningful to you.

Priority

The priority of the message flow is entered here -- 1 receives the highest priority (most

urgent) and 255 receives the lowest priority (least urgent). Priority 0 is reserved. Flows

that are not prioritized by any rule receive lowest priority.

Protocol

The protocol used by the messages. The common choices can be selected from the

drop-down menu. To specify any other protocol, enter its protocol number (as assigned by

the IANA) in the Protocol box.

Source IP Range

The rule applies to a flow of messages whose LAN-side IP address falls within the range

set here.

Source Port Range

The rule applies to a flow of messages whose LAN-side port number is within the range

set here.

Destination IP Range

The rule applies to a flow of messages whose WAN-side IP address falls within the range

set here.

Destination Port Range

The rule applies to a flow of messages whose WAN-side port number is within the range

set here.

Add/Edit StreamEngine Rule

Advanced_Routing

Add/Edit Route

Adds a new route to the IP routing table or edits an existing route.

Enable: Specifies whether the entry will be enabled or disabled.

Destination IP: The IP address of packets that will take this route.

Netmask: One bits in the mask specify which bits of the IP address must match.

Gateway: Specifies the next hop to be taken if this route is used. A gateway of 0.0.0.0 implies

there is no next hop, and the IP address matched is directly connected to the router on the

interface specified: LAN or WAN.

Interface: Specifies the interface -- LAN or WAN -- that the IP packet must use to transit out of

the router, when this route is used.

Metric: The route metric is a value from 1 to 16 that indicates the cost of using this route. A

value of 1 is the lowest cost, and 15 is the highest cost. A value of 16 indicates that the route is

not reachable from this router. When trying to reach a particular destination, computers on your

network will select the best route, ignoring unreachable routes.

Save: Saves the new or edited route in the following list. When finished updating the routing

table, you must still click the Save Settings button at the top of the page to make the changes

effective and permanent.

Routes List

The section shows the current routing table entries. Certain required routes are predefined and

cannot be changed. Routes that you add can be changed by clicking the Edit icon, or deleted

by clicking the Delete icon. When you click the Edit icon, the item is highlighted, and the "Edit

Route" section is activated for editing.

Advanced_Access Control

The Access Control section allows you to control access in and out of devices on your network. Use

this feature as Parental Controls to only grant access to approved sites, limit web access based on

time or dates, and/or block access from applications such as peer-to-peer utilities or games.

Enable

By default, the Access Control feature is disabled. If you need Access Control, check this

option.

When Access Control is disabled, every device on the LAN has unrestricted access

to the Internet. However, if you enable Access Control, Internet access is restricted

for those devices that have an Access Control Policy configured for them. All other

devices have unrestricted access to the Internet.

Policy Wizard

The Policy Wizard guides you through the steps of defining each access control policy. A

policy is the "Who, What, When, and How" of access control -- whose computer will be

affected by the control, what internet addresses are controlled, when will the control be in

effect, and how is the control implemented. You can define multiple policies. The Policy Wizard

starts when you click the button below and also when you edit an existing policy.

Add Policy

Click this button to start creating a new access control policy.

Policy Table

This section shows the currently defined access control policies. A policy can be changed by

clicking the Edit icon, or deleted by clicking the Delete icon. When you click the Edit icon, the

Policy Wizard starts and guides you through the process of changing a policy. You can enable

or disable specific policies in the list by clicking the "Enable" checkbox.

Advanced_WEB Filter

This section is where you add the Web sites to be used for Access Control. The Web sites listed here

are used when the Web Filter option is enabled in Access Control.

The Web Filter section is one of two means by which you can specify the web sites you want to allow.

You also have the alternative of using the Sentinel Parental Controls Service, which allows you to

specify broad categories of web sites and saves you the trouble of entering specific web site URLs.

For more information about the Sentinel service, refer to Tools → Sentinel.

Web Filter Parameters

Web Site

Enter the address of the web site that you want to allow; for example: google.com. Do

not enter the http:// preceding the address. Enter the most inclusive domain; for example,

enter u-media.com and access will be permitted to both www.u-media.com and

support.u-media.com.

Many web sites construct pages with images and content from other web sites.

Access will be forbidden if you do not enable all the web sites used to construct

a page. For example, to access my.yahoo.com, you need to enable access to

yahoo.com, yimg.com, and doubleclick.net.

Add/Edit Web Site

This is where you can add Web sites to the Allowed Web Site List or change entries in the

Allowed Web Site List.

Enable

Entries in the Allowed Web Site List can be activated or deactivated with this checkbox.

New entries are activated by default.

Allowed Web Site List

The section lists the currently allowed web sites. An allowed web site can be changed by

clicking the Edit icon, or deleted by clicking the Delete icon. When you click the Edit icon, the

item is highlighted, and the "Edit Web Site" section is activated for editing.

Advanced_MAC Address Filter

The MAC address filter section can be used to filter network access by machines based on the unique

MAC addresses of their network adapter(s). It is most useful to prevent unauthorized wireless devices

from connecting to your network. A MAC address is a unique ID assigned by the manufacturer of the

network adapter.

Enable MAC Address Filter

When this is enabled, computers are granted or denied network access depending on the

mode of the filter.

Misconfiguration of this feature can prevent any machine from accessing the

network. In such a situation, you can regain access by activating the factory

defaults button on the router itself.

Filter Settings

Mode

When "only allow listed machines" is selected, only computers with MAC addresses listed

in the MAC Address List are granted network access. When "only deny listed machines"

is selected, any computer with a MAC address listed in the MAC Address List is refused

access to the network.

Filter Wireless Clients

When this is selected, the MAC address filters will be applied to wireless network clients.

Filter Wired Clients

When this is selected, the MAC address filters will be applied to wired network clients.

Add/Edit MAC Address

In this section, you can add entries to the MAC Address List below, or edit existing entries.

clicking the Edit icon, or deleted by clicking the Delete icon. When you click the Edit icon, the

item is highlighted, and the "Edit MAC Address" section is activated for editing.

Advanced_Firewall

The router provides a tight firewall by virtue of the way NAT works. Unless you configure the router to

the contrary, the NAT does not respond to unsolicited incoming requests on any port, thereby making

your LAN invisible to Internet cyber attackers. However, some network applications cannot run with a

tight firewall. Those applications need to selectively open ports in the firewall to function correctly. The

options on this page control several ways of opening the firewall to address the needs of specific types

of applications. See also Virtual Server, Port Forwarding, Application Rules, and UPnP for related

options.

Firewall Settings

Enable SPI

SPI ("stateful packet inspection" also known as "dynamic packet filtering") helps to

prevent cyber attacks by tracking more state per session. It validates that the traffic

passing through that session conforms to the protocol. When the protocol is TCP, SPI

checks that packet sequence numbers are within the valid range for the session,

discarding those packets that do not have valid sequence numbers.

Whether SPI is enabled or not, the router always tracks TCP connection states and

ensures that each TCP packet's flags are valid for the current state.

NAT Endpoint Filtering

The NAT Endpoint Filtering options control how the router's NAT manages incoming

connection requests to ports that are already being used.

Endpoint Independent

Once a LAN-side application has created a connection through a specific port, the NAT

will forward any incoming connection requests with the same port to the LAN-side

application regardless of their origin. This is the least restrictive option, giving the best

connectivity and allowing some applications (P2P applications in particular) to behave

almost as if they are directly connected to the Internet.

Address Restricted

The NAT forwards incoming connection requests to a LAN-side host only when they come

from the same IP address with which a connection was established. This allows the

remote application to send data back through a port different from the one used when the

outgoing session was created.

Port And Address Restricted

The NAT does not forward any incoming connection requests with the same port address

as an already establish connection.

Note that some of these options can interact with other port restrictions. Endpoint Independent

Filtering takes priority over inbound filters or schedules, so it is possible for an incoming

session request related to an outgoing session to enter through a port in spite of an active

inbound filter on that port. However, packets will be rejected as expected when sent to blocked

ports (whether blocked by schedule or by inbound filter) for which there are no active sessions.

Port and Address Restricted Filtering ensures that inbound filters and schedules work precisely,

but prevents some level of connectivity, and therefore might require the use of port triggers,

virtual servers, or port forwarding to open the ports needed by the application. Address

Restricted Filtering gives a compromise position, which avoids problems when communicating

with certain other types of NAT router (symmetric NATs in particular) but leaves inbound filters

and scheduled access working as expected.

UDP Endpoint Filtering

Controls endpoint filtering for packets of the UDP protocol.

TCP Endpoint Filtering

Controls endpoint filtering for packets of the TCP protocol.

DMZ Host

DMZ means "Demilitarized Zone." If an application has trouble working from behind the router,

you can expose one computer to the Internet and run the application on that computer.

When a LAN host is configured as a DMZ host, it becomes the destination for all incoming

packets that do not match some other incoming session or rule. If any other ingress rule is in

place, that will be used instead of sending packets to the DMZ host; so, an active session,

virtual server, active port trigger, or port forwarding rule will take priority over sending a packet

to the DMZ host. (The DMZ policy resembles a default port forwarding rule that forwards every

port that is not specifically sent anywhere else.)

The router provides only limited firewall protection for the DMZ host. The router does not

forward a TCP packet that does not match an active DMZ session, unless it is a connection

establishment packet (SYN). Except for this limited protection, the DMZ host is effectively

"outside the firewall". Anyone considering using a DMZ host should also consider running a

firewall on that DMZ host system to provide additional protection.

Packets received by the DMZ host have their IP addresses translated from the WAN-side IP

address of the router to the LAN-side IP address of the DMZ host. However, port numbers are

not translated; so applications on the DMZ host can depend on specific port numbers.

The DMZ capability is just one of several means for allowing incoming requests that might

appear unsolicited to the NAT. In general, the DMZ host should be used only if there are no

other alternatives, because it is much more exposed to cyber attacks than any other system on

the LAN. Thought should be given to using other configurations instead: a virtual server, a port

forwarding rule, or a port trigger. Virtual servers open one port for incoming sessions bound for

a specific application (and also allow port redirection and the use of ALGs). Port forwarding is

rather like a selective DMZ, where incoming traffic targeted at one or more ports is forwarded

to a specific LAN host (thereby not exposing as many ports as a DMZ host). Port triggering is a

special form of port forwarding, which is activated by outgoing traffic, and for which ports are

only forwarded while the trigger is active.

Few applications truly require the use of the DMZ host. Following are examples of when a

DMZ host might be required:

• A host needs to support several applications that might use overlapping ingress ports

such that two port forwarding rules cannot be used because they would potentially be in

conflict.

• To handle incoming connections that use a protocol other than ICMP, TCP, UDP, and

IGMP (also GRE and ESP, when these protocols are enabled by the PPTP and IPSec

ALGs ).

Enable DMZ

Putting a computer in the DMZ may expose that computer to a variety of

security risks. Use of this option is only recommended as a last resort.

DMZ IP Address

Specify the LAN IP address of the LAN computer that you want to have unrestricted

Internet communication. If this computer obtains its address Automatically using DHCP,

then you may want to make a static reservation on the Basic → Network Settings page so

that the IP address of the DMZ computer does not change.

Non-UDP/TCP/ICMP LAN Sessions

When a LAN application that uses a protocol other than UDP, TCP, or ICMP initiates a session

to the Internet, the router's NAT can track such a session, even though it does not recognize

the protocol. This feature is useful because it enables certain applications (most importantly a

single VPN connection to a remote host) without the need for an ALG.

Note that this feature does not apply to the DMZ host (if one is enabled). The DMZ host always

handles these kinds of sessions.

Enable

Enabling this option (the default setting) enables single VPN connections to a remote host.

(But, for multiple VPN connections, the appropriate VPN ALG must be used.) Disabling

this option, however, only disables VPN if the appropriate VPN ALG is also disabled.

Application Level Gateway (ALG) Configuration

Here you can enable or disable ALGs. Some protocols and applications require special

handling of the IP payload to make them work with network address translation (NAT). Each

ALG provides special handling for a specific protocol or application. A number of ALGs for

common applications are enabled by default.

PPTP

Allows multiple machines on the LAN to connect to their corporate networks using PPTP

protocol. When the PPTP ALG is enabled, LAN computers can establish PPTP VPN

connections either with the same or with different VPN servers. When the PPTP ALG is

disabled, the router allows VPN operation in a restricted way -- LAN computers are

typically able to establish VPN tunnels to different VPN Internet servers but not to the

same server. The advantage of disabling the PPTP ALG is to increase VPN performance.

Enabling the PPTP ALG also allows incoming VPN connections to a LAN side VPN server

(refer to Virtual Server).

IPSec (VPN)

Allows multiple VPN clients to connect to their corporate networks using IPSec. Some

VPN clients support traversal of IPSec through NAT. This option may interfere with the

operation of such VPN clients. If you are having trouble connecting with your corporate

network, try disabling this option.

Check with the system administrator of your corporate network whether your VPN client

supports NAT traversal.

Note that L2TP VPN connections typically use IPSec to secure the connection. To achieve

multiple VPN pass-through in this case, the IPSec ALG must be enabled.

RTSP

Allows applications that use Real Time Streaming Protocol to receive streaming media

from the internet. QuickTime and Real Player are some of the common applications using

this protocol.

Windows/MSN Messenger

Supports use on LAN computers of Microsoft Windows Messenger (the Internet

messaging client that ships with Microsoft Windows) and MSN Messenger. The SIP ALG

must also be enabled when the Windows Messenger ALG is enabled.

FTP

Allows FTP clients and servers to transfer data across NAT. Refer to the

Advanced → Virtual Server page if you want to host an FTP server.

H.323 (Netmeeting)

Allows H.323 (specifically Microsoft Netmeeting) clients to communicate across NAT. Note

that if you want your buddies to call you, you should also set up a virtual server for

NetMeeting. Refer to the Advanced → Virtual Server page for information on how to set

up a virtual server.

SIP

Allows devices and applications using VoIP (Voice over IP) to communicate across NAT.

Some VoIP applications and devices have the ability to discover NAT devices and work

around them. This ALG may interfere with the operation of such devices. If you are having

trouble making VoIP calls, try turning this ALG off.

Wake-On-LAN

This feature enables forwarding of "magic packets" (that is, specially formatted wake-up

packets) from the WAN to a LAN computer or other device that is "Wake on LAN" (WOL)

capable. The WOL device must be defined as such on the Advanced → Virtual Server

page. The LAN IP address for the virtual server is typically set to the broadcast address

192.168.2.255. The computer on the LAN whose MAC address is contained in the magic

packet will be awakened.

MMS

Allows Windows Media Player, using MMS protocol, to receive streaming media from the

internet.

Advanced_Inbound Filter

When you use the Virtual Server, Gaming, or Remote Administration features to open specific ports to

traffic from the Internet, you could be increasing the exposure of your LAN to cyber attacks from the

Internet. In these cases, you can use Inbound Filters to limit that exposure by specifying the IP

addresses of internet hosts that you trust to access your LAN through the ports that you have opened.

You might, for example, only allow access to a game server on your home LAN from the computers of

friends whom you have invited to play the games on that server.

Inbound Filters can be used for limiting access to a server on your network to a system or group of

systems. Filter rules can be used with Virtual Server, Gaming, or Remote Administration features.

Each filter can be used for several functions; for example a "Game Clan" filter might allow all of the

members of a particular gaming group to play several different games for which gaming entries have

been created. At the same time an "Admin" filter might only allows systems from your office network to

access the WAN admin pages and an FTP server you use at home. If you add an IP address to a filter,

the change is effected in all of the places where the filter is used.

Add/Edit Inbound Filter Rule

Here you can add entries to the Inbound Filter Rules List below, or edit existing entries.

Name

Enter a name for the rule that is meaningful to you.

Action

The rule can either Allow or Deny messages.

Source IP Range

Define the ranges of Internet addresses this rule applies to. For a single IP address, enter

the same address in both the Start and End boxes. Up to eight ranges can be entered.

The Enable checkbox allows you to turn on or off specific entries in the list of ranges.

Save

Saves the new or edited Inbound Filter Rule in the following list. When finished updating

the Inbound Filter Rules List, you must still click the Save Settings button at the top of the

page to make the changes effective and permanent.

Inbound Filter Rules List

The section lists the current Inbound Filter Rules. An Inbound Filter Rule can be changed by

clicking the Edit icon, or deleted by clicking the Delete icon. When you click the Edit icon, the

item is highlighted, and the "Edit Inbound Filter Rule" section is activated for editing.

In addition to the filters listed here, two predefined filters are available wherever inbound filters

can be applied:

Allow All

Permit any WAN user to access the related capability.

Deny All

Prevent all WAN users from accessing the related capability. (LAN users are not affected

by Inbound Filter Rules.)

Advanced_Advanced Wireless

Transmit Power

Normally the wireless transmitter operates at 100% power. In some circumstances, however,

there might be a need to isolate specific frequencies to a smaller area. By reducing the power

of the radio, you can prevent transmissions from reaching beyond your corporate/home office

or designated wireless area.

Beacon Period

Beacons are packets sent by a wireless router to synchronize wireless devices. Specify a

Beacon Period value between 20 and 1000. The default value is set to 100 milliseconds.

RTS Threshold

This setting should remain at its default value of 2346. If you encounter inconsistent data flow,

only minor modifications to the value are recommended.

Fragmentation Threshold

This setting should remain at its default value of 2346. Setting the Fragmentation value too low

may result in poor performance.

DTIM Interval

A DTIM is a countdown informing clients of the next window for listening to broadcast and

multicast messages. When the wireless router has buffered broadcast or multicast messages

for associated clients, it sends the next DTIM with a DTIM Interval value. Wireless clients

detect the beacons and awaken to receive the broadcast and multicast messages. The default

value is 1. Valid settings are between 1 and 255.

802.11d Enable

Enables 802.11d operation. 802.11d is a wireless specification for operation in additional

regulatory domains. This supplement to the 802.11 specifications defines the physical layer

requirements (channelization, hopping patterns, new values for current MIB attributes, and

other requirements to extend the operation of 802.11 WLANs to new regulatory domains

(countries). The current 802.11 standard defines operation in only a few regulatory domains

(countries). This supplement adds the requirements and definitions necessary to allow 802.11

WLAN equipment to operate in markets not served by the current standard. Enable this option

if you are operating in one of these "additional regulatory domains".

WMM Enable

Enabling WMM can help control latency and jitter when transmitting multimedia content over a

wireless connection.

Short GI

Using a short (400ns) guard interval can increase throughput. However, it can also increase

error rate in some installations, due to increased sensitivity to radio-frequency reflections.

Select the option that works best for your installation.

Extra Wireless Protection

Extra protection for neighboring 11b wireless networks. Turn this option off to reduce the

adverse effect of legacy wireless networks on 802.11ng performance.

WDS Enable

When WDS is enabled, this access point functions as a wireless repeater and is able to

wirelessly communicate with other APs via WDS links. Note that WDS is incompatible with

WPA -- both features cannot be used at the same time. A WDS link is bidirectional; so this AP

must know the MAC Address (creates the WDS link) of the other AP, and the other AP must

have a WDS link back to this AP. Make sure the APs are configured with same channel

number.

WDS AP MAC Address

Specifies one-half of the WDS link. The other AP must also have the MAC address of this AP

to create the WDS link back to this AP. Enter a MAC address for each of the other APs that

you want to connect with WDS.

Advanced_Network

UPnP

UPnP is short for Universal Plug and Play, which is a networking architecture that provides

compatibility among networking equipment, software, and peripherals. This router has optional

UPnP capability, and can work with other UPnP devices and software.

Enable UPnP

If you need to use the UPnP functionality, you can enable it here.

WAN Ping

Pinging public WAN IP addresses is a common method used by hackers to test whether your

WAN IP address is valid.

Enable WAN Ping Respond

If you leave this option unchecked, you are causing the router to ignore ping commands

for the public WAN IP address of the router.

WAN Port Speed

Normally, this is set to "auto". If you have trouble connecting to the WAN, try the other settings.

Multicast Streams

The router uses the IGMP protocol to support efficient multicasting -- transmission of identical

content, such as multimedia, from a source to a number of recipients.

Enable Multicast Streams

This option must be enabled if any applications on the LAN participate in a multicast

group. If you have a multimedia LAN application that is not receiving content as expected,

try enabling this option.

Advanced_WISH

WISH is short for Wireless Intelligent Stream Handling, a technology developed to enhance your

experience of using a wireless network by prioritizing the traffic of different applications.

WISH

Enable WISH

Enable this option if you want to allow WISH to prioritize your traffic.

Priority Classifiers

HTTP

Allows the router to recognize HTTP transfers for many common audio and video

streams and prioritize them above other traffic. Such streams are frequently used by

digital media players.

Windows Media Center

Enables the router to recognize certain audio and video streams generated by a

Windows Media Center PC and to prioritize these above other traffic. Such streams are

used by systems known as Windows Media Extenders, such as the Xbox 360.

Automatic

When enabled, this option causes the router to automatically attempt to prioritize traffic

streams that it doesn't otherwise recognize, based on the behaviour that the streams

exhibit. This acts to deprioritize streams that exhibit bulk transfer characteristics, such

as file transfers, while leaving interactive traffic, such as gaming or VoIP, running at a

normal priority.

Add/Edit WISH Rule

A WISH Rule identifies a specific message flow and assigns a priority to that flow. For most

applications, the priority classifiers ensure the right priorities and specific WISH Rules are not

required.

WISH supports overlaps between rules. If more than one rule matches for a specific message

flow, the rule with the highest priority will be used.

Enable

Specifies whether the entry will be active or inactive.

Name

Create a name for the rule that is meaningful to you.

Priority

The priority of the message flow is entered here. Four priorities are defined:

• BK: Background (least urgent).

• BE: Best Effort.

• VI: Video.

• VO: Voice (most urgent).

Protocol

The protocol used by the messages.

Host 1 IP Range

The rule applies to a flow of messages for which one computer's IP address falls within

the range set here.

Host 1 Port Range

The rule applies to a flow of messages for which host 1's port number is within the

range set here.

Host 2 IP Range

The rule applies to a flow of messages for which the other computer's IP address falls

within the range set here.

Host 2 Port Range

The rule applies to a flow of messages for which host 2's port number is within the

range set here.

Save/Update

Record the changes you have made into the following list.

Clear

Re-initialize this area of the screen, discarding any changes you have made.

WISH Rules

This section lists the defined WISH Rules. Click the Enable checkbox at the left to directly

activate or de-activate the entry. An entry can be changed by clicking the Edit icon or can be

deleted by clicking the Delete icon. When you click the Edit icon, the item is highlighted, and

the "Edit WISH Rule" section is activated for editing.

Advanced_Wi-Fi PROTECTED SETUP

Wi-Fi Protected Setup

Enable

Enable the Wi-Fi Protected Setup feature.

Lock Wireless Security Settings

Locking the wireless security settings prevents the settings from being changed by any

new external registrar using its PIN. Devices can still be added to the wireless network

using Wi-Fi Protected Setup. It is still possible to change wireless network settings with

Manual Wireless Network Setup, Wireless Network Setup Wizard, or an existing

external WLAN Manager Registrar.

PIN Settings

A PIN is a unique number that can be used to add the router to an existing network or to create

a new network. The default PIN may be printed on the bottom of the router. For extra security,

a new PIN can be generated. You can restore the default PIN at any time. Only the

Administrator ("admin" account) can change or reset the PIN.

Current PIN

Shows the current value of the router's PIN.

Reset PIN to Default

Restore the default PIN of the router.

Generate New PIN

Create a random number that is a valid PIN. This becomes the router's PIN. You can

then copy this PIN to the user interface of the registrar.

Add Wireless Station

This Wizard helps you add wireless devices to the wireless network.

The wizard will either display the wireless network settings to guide you through manual

configuration, prompt you to enter the PIN for the device, or ask you to press the configuration

button on the device. If the device supports Wi-Fi Protected Setup and has a configuration

button, you can add it to the network by pressing the configuration button on the device and

then on the router within 60 seconds. The WPS status LED on the router will become solid if

the device has been successfully added to the network.

There are several ways to add a wireless device to your network. Access to the wireless

network is controlled by a “registrar”. A registrar only allows devices onto the wireless network

if you have entered the PIN, or pressed a special Wi-Fi Protected Setup button on the device.

The router acts as a registrar for the network, although other devices may act as a registrar as

well.

Add Wireless Device Wizard

Start the wizard.

Tools

The Tools tab provides the following configuration options: Admin, Time, Syslog, Email Settings,

System, Firmware, Dynamic DNS, Windows Connect Now, System Check & Schedules.

Tools_Admin

The Admin option is used to set a password for access to the Web-based management. By default

there is no password configured. It is highly recommended that you create a password to keep your

new router secure.

Admin Password

Enter a password for the user "admin", who will have full access to the Web-based

management interface.

User Password

Enter a password for the user "user", who will have read-only access to the Web-based

management interface.

Gateway Name

The name of the router can be changed here.

Enable Remote Management

Enabling Remote Management allows you to manage the router from anywhere on the Internet.

Disabling Remote Management allows you to manage the router only from computers on your

LAN.

Remote Admin Port

The port that you will use to address the management interface from the Internet. For example,

if you specify port 1080 here, then, to access the router from the Internet, you would use a URL

of the form: http://my.domain.com:1080/.

Remote Admin Inbound Filter

Select a filter that controls access as needed for this admin port. If you do not see the filter you

need in the list of filters, go to the Advanced → Inbound Filter screen and create a new filter.

Tools_Time

The Time Configuration option allows you to configure, update, and maintain the correct time on the

router's internal system clock. From this section you can set the time zone that you are in and set the

Time Server. Daylight saving can also be configured to automatically adjust the time when needed.

Time Configuration

Current Router Time

Displays the time currently maintained by the router. If this is not correct, use the following

options to configure the time correctly.

Time Zone

Select your local time zone from pull down menu.

Enable Daylight Saving

Check this option if your location observes daylight saving time.

Daylight Saving Offset

Select the time offset, if your location observes daylight saving time.

DST Start and DST End

Select the starting and ending times for the change to and from daylight saving time. For

example, suppose for DST Start you select Month="Oct", Week="3rd", Day="Sun" and

Time="2am". This is the same as saying: "Daylight saving starts on the third Sunday of

October at 2:00 AM."

Automatic Time Configuration

Enable NTP Server

Select this option if you want to synchronize the router's clock to a Network Time Server

over the Internet. If you are using schedules or logs, this is the best way to ensure that the

schedules and logs are kept accurate.

NTP Server Used

Select a Network Time Server for synchronization. You can type in the address of a time

server or select one from the list. If you have trouble using one server, select another.

Set the Date and Time Manually

If you do not have the NTP Server option in effect, you can either manually set the time for

your router here, or you can click the Copy Your Computer’s Time Settings button to copy

the time from the computer you are using. (Make sure that computer's time is set correctly.)

If the router loses power for any reason, it cannot keep its clock running, and will not have

the correct time when it is started again. To maintain correct time for schedules and logs,

either you must enter the correct time after you restart the router, or you must enable the

NTP Server option.

Tools_Syslog

This section allows you to archive your log files to a Syslog Server.

Enable Logging to Syslog Server

Enable this option if you have a syslog server currently running on the LAN and wish to send

log messages to it.

Syslog Server IP Address

On Schedule

Select this option if you want logs to be sent by email according to a schedule.

Schedule

If you selected the On Schedule option, select one of the defined schedule rules. If you do

not see the schedule you need in the list of schedules, go to the Tools -> Schedules

screen and create a new schedule.

Normally email is sent at the start time defined for a schedule, and the

schedule end time is not used. However, rebooting the router during the

schedule period will cause additional emails to be sent.

Tools_System

This section allows you to manage the router's configuration settings, reboot the router, and restore

the router to the factory default settings. Restoring the unit to the factory default settings will erase all

settings, including any rules that you've created.

Save Settings To Local Hard Drive

This option allows you to save the router's configuration to a file on your computer. Be sure to

save the configuration before performing a firmware upgrade.

Load Settings From Local Hard Drive

Use this option to restore previously saved router configuration settings.

Restore To Factory Default Settings

This option restores all configuration settings back to the settings that were in effect at the time

the router was shipped from the factory. Any settings that have not been saved will be lost. If

you want to save your router configuration settings, use the Save Settings option above.

Reboot The Device

This restarts the router. Useful for restarting when you are not near the device.

Tools_Firmware

The Firmware Upgrade section can be used to update to the latest firmware code to improve

functionality and performance. To check for the latest firmware, click the Check Online Now button. If

you would like to be notified when new firmware is released, place a checkmark in the box next to

Email Notification of Newer Firmware Version.

To upgrade the firmware, follow these steps:

1. Click the Browse button to locate the upgrade file on your computer.

2. Once you have found the file to be used, click the Upload button below to start the firmware

upgrade process. This can take a minute or more.

3. Wait for the router to reboot. This can take another minute or more.

4. Confirm updated firmware revision on status page.

Firmware Information

Here are displayed the version numbers of the firmware currently installed in your router and

the most recent upgrade that is available.

Check Online

This option will check support site to see if you have the latest version of the firmware

available. If a newer version is available, download instructions will be displayed.

Firmware Upgrade

Firmware upgrade cannot be performed from a wireless device. To perform an

upgrade, ensure that you are using a PC that is connected to the router by wire.

Some firmware upgrades reset the configuration options to the factory defaults.

Before performing an upgrade, be sure to save the current configuration from

the Tools -> Admin screen.

Upload

Once you have a firmware update on your computer, use this option to browse for the file

and then upload the information into the router.

Tools_Dynamic DNS

The Dynamic DNS feature allows you to host a server (Web, FTP, Game Server, etc.) using a domain

name that you have purchased (www.whateveryournameis.com) with your dynamically assigned IP

address. Most broadband Internet Service Providers assign dynamic (changing) IP addresses. When

you use a Dynamic DNS service provider, your friends can enter your host name to connect to your

server, no matter what your IP address is.

Enable Dynamic DNS

Enable this option only if you have purchased your own domain name and registered with a

dynamic DNS service provider. The following paramters are displayed when the option is

enabled.

Server Address

Select a dynamic DNS service provider from the pull-down list.

Host Name

Enter your host name, fully qualified; for example: myhost.mydomain.net.

Username or Key

Enter the username or key provided by your service provider. If the Dynamic DNS provider

supplies only a key, enter that key in all three fields.

Password or Key

Enter the password or key provided by your service provider. If the Dynamic DNS provider

supplies only a key, enter that key in all three fields.

Verify Password or Key

Re-type the password or key provided by your service provider. If the Dynamic DNS provider

supplies only a key, enter that key in all three fields.

Timeout

The time between periodic updates to the Dynamic DNS, if your dynamic IP address has not

changed. The timeout period is entered in hours.

If a dynamic DNS update fails for any reason (for example, when incorrect parameters are

entered), the router automatically disables the Dynamic DNS feature and records the

failure in the log.

After configuring the router for dynamic DNS, you can open a browser and navigate to the

URL for your domain (for example http://www.mydomain.info) and the router will attempt

to forward the request to port 80 on your LAN. If, however, you do this from a LAN-side

computer and there is no virtual server defined for port 80, the router will return the

router's configuration home page. Refer to the Advanced -> Virtual Server configuration

page to set up a virtual server.

Tools_System Check

Ping Test

"Ping" is an Internet utility function that sends a series of short messages to a target computer

and reports the results. You can use it to test whether a computer is running, and to get an

idea of the quality of the connection to that computer, based on the speed of the responses.

Host Name or IP Address

Enter either the IP address of the target computer or enter its fully qualified domain name.

Ping

Start pinging the specified host.

Stop

The host is pinged repeatedly until you press this button.

Example:

Host Name or IP Address

www.whitehouse.gov

Ping Result

Please wait, resolving www.whitehouse.gov....

Resolved to 205.161.7.102.

Place a checkmark in the boxes for the desired days or select the All Week radio button to

select all seven days of the week.

All Day - 24 hrs

Select this option if you want this schedule in effect all day for the selected day(s).

Start Time

If you don't use the All Day option, then you enter the time here. The start time is entered

in two fields. The first box is for the hour and the second box is for the minute. Email

events are normally triggered only by the start time.

End Time

The end time is entered in the same format as the start time. The hour in the first box and

the minutes in the second box. The end time is used for most other rules, but is not

normally used for email events.

Save

Saves the new or edited Schedule Rule in the following list. When finished updating the

Schedule Rules, you must still click the Save Settings button at the top of the page to

make the changes effective and permanent.

Schedule Rules List

This section shows the currently defined Schedule Rules. A Schedule Rule can be changed by

clicking the Edit icon, or deleted by clicking the Delete icon. When you click the Edit icon, the

item is highlighted, and the "Edit Schedule Rule" section is activated for editing.

Status

The Status tab provides the following configuration options: Device Info, Wireless, Routing, Logs,

Statistics and Active Sessions.

Status_Device info

All of your Internet and network connection details are displayed on the Device Info page. The

firmware version is also displayed here.

Some browsers have limitations that make it impossible to update the WAN status display

when the status changes. Some browsers require that you refresh the display to obtain

updated status. Some browsers report an error condition when trying to obtain WAN status.

Depending on the type of WAN connection, you can take one of the following sets of actions:

DHCP Connection

Clicking the DHCP Release button unassigns the router's IP address. The router will not

respond to IP messages from the WAN side until you click the DHCP Renew button or

power-up the router again. Clicking the DHCP Renew button causes the router to request a

new IP address from the ISP's server.

PPPoE, PPTP, L2TP Connection

Depending on whether the WAN connection is currently established, you can click either the

Connect to attempt to establish the WAN connection or the Disconnect to break the WAN

connection.

BigPond Connection

Depending on whether you are currently logged in to BigPond, you can click either the

BigPond Login to attempt to establish the WAN connection or the BigPond Logout to break

the WAN connection.

LAN Computers

This area of the screen continually updates to show all DHCP enabled computers and devices

connected to the LAN side of your router. The detection "range" is limited to the address range

as configured in DHCP Server. Computers that have an address outside of this range will not

show. If the DHCP Client (i.e. a computer configured to "Automatically obtain an address")

supplies a Host Name then that will also be shown. Any computer or device that has a static IP

address that lies within the detection "range" may show, however its host name will not.

IGMP Multicast memberships

If IGMP is enabled, this area of the screen show all multicast groups of which any LAN devices

are members.

Status_Wireless

The wireless section allows you to view the wireless clients that are connected to your wireless router.

MAC Address

The Ethernet ID (MAC address) of the wireless client.

IP Address

The LAN-side IP address of the client.

Mode

The transmission standard being used by the client. Values are 11a, 11b, or 11g for 802.11a,

802.11b, or 802.11g respectively.

Rate

The actual transmission rate of the client in megabits per second.

Signal

This is a relative measure of signal quality. The value is expressed as a percentage of

theoretical best quality. Signal quality can be reduced by distance, by interference from other

radio-frequency sources (such as cordless telephones or neighboring wireless networks), and

by obstacles between the router and the wireless device.

Status_Routing

The routing section displays all of the routing details configured for your router.

A value of 0.0.0.0 for gateway means there is no next hop, and the IP address is directly connected to

the router on the interface specified: LAN or WAN. A value of 0.0.0.0 in both the destination IP and

netmask means that this is the default route.

Status_Logs

The router automatically logs (records) events of possible interest in its internal memory. If there is not

enough internal memory for all events, logs of older events are deleted, but logs of the latest events

are retained. The Logs option allows you to view the router logs. You can define what types of events

you want to view and the level of events to view. This router also has external Syslog Server support

so you can send the log files to a computer on your network that is running a Syslog utility.

What to View

Select the kinds of events that you want to view.

• Firewall and Security

• System

TX Packets Dropped

The number of packets that were dropped while being sent, due to errors, collisions, or router

resource limitations.

RX Packets Dropped

The number of packets that were dropped while being received, due to errors, collisions, or

router resource limitations.

Collisions

The number of packets that were dropped due to Ethernet collisions (two or more devices

attempting to use an Ethernet circuit at the same time).

Errors

The number of transmission failures that cause loss of a packet. A noisy radio-frequency

environment can cause a high error rate on the wireless LAN.

Status_Active Sessions

The Active Sessions page displays full details of active sessions through your router. A session is a

conversation between a progam or application on a LAN-side computer and a program or application

on a WAN-side computer.

Internal

The IP address and port number of the LAN-side application.
