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.
Transmission Rate (Transfer Rate)
The SMCWBR14-N 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-N to operate at the maximum transmission (data) rate. When the
communication quality drops below a certain level, the SMCWBR14-N 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-N 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 infrastructure 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 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).
Roaming in an ESS network diagram
The SMCWBR14-N 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-N 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)

Installation Considerations
The SMCWBR14-N 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:
Keep the number of walls and ceilings between the SMCWBR14-N 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.
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.
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.
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

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.
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
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.
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.
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
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.
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.
Wireless Networking technology enables ubiquitous communication
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
MAC Address Authentication: If this is selected, the user must connect from the same
computer whenever logging into the wireless network.
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
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,
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 here, and you have a wireless laptop with a name of chris,
that laptop will be known as 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
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 This means that addresses to can be made available for allocation by the DHCP Server.
Your router uses for the IP address. You've assigned a computer that you
want to designate as a Web server with a static IP address of You've
assigned another computer that you want to designate as an FTP server with a static IP
address of Therefore the starting IP address for your DHCP IP address
range needs to be or greater.
Suppose you configure the DHCP Server to manage addresses From:
To: This means that to and to 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 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
Windows 2000
Windows XP
Mac OS X
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.
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.
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
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
Number of Dynamic DHCP Clients
In this section you can see what LAN devices are currently leasing IP addresses.
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.
The Reserve option converts this dynamic IP allocation into a DHCP Reservation and
adds the corresponding entry to the DHCP Reservations List.
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.
You are hosting a Web Server on a PC that has LAN IP Address of 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:
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

Virtual Server Parameters
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 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.
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.

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
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.
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.
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).
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 Tools → 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

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

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.

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
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
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.
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.
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.
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).
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.
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.
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.
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.
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 The computer on the LAN whose MAC address is contained in the magic
packet will be awakened.
Allows Windows Media Player, using MMS protocol, to receive streaming media from the
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.
Enter a name for the rule that is meaningful to you.
The rule can either Allow or Deny messages.
Source IP Range

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 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
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.

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.
