2. 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 TEW-639GR 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
TEW-639GR to operate at the maximum transmission (data) rate. When the communication quality drops
below a certain level, the TEW-639GR 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 TEW-639GR gradually increases the transmission (data) rate again until it reaches the
highest available transmission rate.
2.1 Introduction
The TEW-639GR 2.4GHz 300Mbps Wireless N Gigabit Router is an high-performance, wireless router that
supports high-speed wireless networking at home, at work or in public places.
Unlike most routers, the TEW-639GR provides data transfers at up to 300Mbps when using 11n connection.
This router is also back 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 speed when you mix
11n and 11b/g devices, but you will not lose the ability to communicate when you incorporate the 11n
standard into your 11b/g network. You may choose to slowly change your network by gradually replacing
the 11b/g devices with 11n devices.

3.3 Installation Considerations
The TEW-639GR 2.4GHz Wireless N Gigabit Router 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 TEW-639GR 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.
3.4 Getting Started
For a typical wireless setup at home, please do the following:
1. You will need broadband Internet access (a Cable or DSL-subscriber line into your home or
office)
2. Consult with your Cable or DSL provider for proper installation of the modem.
3. Connect the Cable or DSL modem to the TEW-639GR Wireless Broadband Router (WAN
port).
4. Ethernet LAN ports of the TEW-639GR are Auto MDI/MDIX and will work with both
Straight-Through and Cross-Over cable.
12
4. Using the Configuration Menu
Whenever you want to configure your TEW-639GR, you can access the Configuration Menu through
your PC by opening the Web-browser and typing in the IP Address of the TEW-639GR. The
TEW-639GR’s default IP Address is http://192.168.10.1
¾ Open the Web browser.
¾ Type in the IP Address of the Router (http://192.168.10.1 )
If you have changed the default IP Address assigned to the TEW-639GR, make sure to
enter the correct IP Address.
¾ Select admin in the User Name field.
¾ Leave the Password blank.
¾ Click Login In.

4.1 Network
4.1.1 Network: WAN Setting
WAN Connection Type
There are several connection types to choose from: Static IP, DHCP, PPPoE, PPTP, L2TP,
and Russia PPTP. If you are unsure of your connection method, please contact your Internet
Service Provider. Static
Used when your ISP provides you a set IP address that does not change. The IP information is
manually entered in your IP configuration settings. You must enter the IP address, Subnet
Mask, Gateway, Primary DNS Server, and Secondary DNS Server. Your ISP provides you with
all of this information.
DHCP
A method of connection where the ISP assigns your IP address when your router requests one
from the ISP's server.
Host Name: Some ISP's may check your computer's Host Name. The Host Name identifies
your system to the ISP's server.
PPPoE
Select this option if your ISP requires you to use a PPPoE (Point to Point Protocol over
Ethernet) connection. DSL providers typically use this option. This method of connection
requires you to enter a Username and Password (provided by your Internet Service Provider)
to gain access to the Internet.
Reconnect Mode: Typically PPPoE connections are not always on. The router allows you to
set the reconnection mode. The settings are:
Always on: A connection to the Internet is always maintained.
On demand: A connection to the Internet is made as needed.
Manual: You have to open up the Web-based management interface and click the Connect
button manually any time that you wish to connect to the Internet.

Maximum Idle Time: Time interval the machine can be idle before the PPPoE connection is
disconnected. The Maximum Idle Time value is only used for the "On demand" and "Manual"
reconnect modes.
L2TP
L2TP (Layer Two Tunneling Protocol) uses a virtual private network to connect to your ISP.
This method of connection requires you to enter a Username and Password (provided by your
Internet Service Provider) to gain access to the Internet.
L2TP Server IP Address: The ISP provides this parameter, if necessary. The value may be
the same as the Gateway IP Address.
Reconnect Mode: Typically PPPoE connections are not always on. The router allows you to
set the reconnection mode. The settings are:
Always on: A connection to the Internet is always maintained.
On demand: A connection to the Internet is made as needed.
Manual: You have to open up the Web-based management interface and click the Connect
button manually any time that you wish to connect to the Internet.
Maximum Idle Time: Time interval the machine can be idle before the PPPoE connection is
disconnected. The Maximum Idle Time value is only used for the "On demand" and "Manual"
reconnect modes.
WAN Interface IP Type
Static: If your ISP has assigned a fixed IP address, select this option. The ISP provides the
values for the following fields for WAN Interface IP Setting: IP Address, Subnet Mask ,
Default Gateway.
Dynamic: If the ISP's servers assign the router's IP addressing upon establishing a connection,
select this option.
PPTP
PPTP (Point to Point Tunneling Protocol) uses a virtual private network to connect to your ISP.
This method of connection is primarily used in Europe. This method of connection requires you
to enter a Username and Password (provided by your Internet Service Provider) to gain
access to the Internet.
PPTP Server IP Address: The ISP provides this parameter, if necessary. The value may be
the same as the Gateway IP Address.
Reconnect Mode: Typically PPPoE connections are not always on. The router allows you to
set the reconnection mode. The settings are:
Always on: A connection to the Internet is always maintained.
On demand: A connection to the Internet is made as needed.

Static: If your ISP has assigned a fixed IP address, select this option. The ISP provides the
values for the following fields for WAN Interface IP Setting: IP Address, Subnet Mask ,
Default Gateway, and optional for DNS Server
Dynamic: If the ISP's servers assign the router's IP addressing upon establishing a connection,
select this option.
Russia PPTP
The Russia PPTP can configure IP address on the WAN interface and establish PPTP to get
IP address, subnet mask, default gateway and DNS for ANOTHER logical IP interface on WAN
port. So the physical WAN port will have 2 logical IP interfaces and can communicate with
internal ISP’s network resources and also communicate with Internet through PPTP tunnel. It is
specified by Russia Cobrina ISP, user can configure it the same as the normal PPTP and
PPTP server IP Address can use the domain name string.
15
WAN MTU Setting
The Maximum Transmission Unit (MTU) is a parameter that determines the largest packet size
(in bytes) that the router will send to the WAN. If LAN devices send larger packets, the router
will break them into smaller packets. Ideally, you should set this to match the MTU of the
connection to your ISP. Typical values are 1500 bytes for an Ethernet connection and 1492
bytes for a PPPoE connection. If the router's MTU is set too high, packets will be fragmented
downstream. If the router's MTU is set too low, the router will fragment packets unnecessarily
and in extreme cases may be unable to establish some connections. In either case, network
performance can suffer. t modes.
MAC Address Clone
Each networking device has it's own unique MAC address defined by the hardware
manufacturer. Some ISP's may check your computer's MAC address. Some ISP's record the
MAC address of the network adapter in the computer or router used to initially connect to their
service. The ISP will then only grant Internet access to requests from a computer or router with
this particular MAC address. This router has a different MAC address than the computer or
router that initially connected to the ISP. If you need to change the MAC address of the
rounter's WAN-side Ethernet interface, either type in an alternate MAC address (for example,
the MAC address of the router initially connected to the ISP) or copy the MAC address of a PC.
To copy the MAC address of the computer that initially connected to the ISP, connect to the
router using that computer and click the Clone Your PC's MAC Address button. The WAN
interface will then use the MAC address of the network adapter in your computer.

4.1.2 Network: LAN Setting
17
IP Address
The IP address of the this device on the local area network. Assign any unused IP address in
the range of IP addresses available for the LAN.
Subnet Mask
The subnet mask of the local area network.
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 (Start and End) 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, 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 192.168.10.1. This means that addresses
192.168.10.2 to 192.168.10.254 can be made available for allocation by the DHCP Server.
Subnet Mask
The subnet mask of the local area network.
Gateway
The IP address of the router on the local area network. For example, 192.168.10.1.
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.
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.
18
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.

4.2 Wireless
4.2.1 Wireless: Basic
21
Radio On/Off
This indicates the wireless operating status. The wireless can be turned on or off by the slide
switch. When the radio is on, the following parameters are in effect.
Wireless 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 wireless
mode. If you have some devices that use a different transmission mode, choose the
appropriate wireless mode. The TEW-639GR supports 2.4GHz wireless networks. There
are many different configuration options available to choose from. Use the drop down list to
select the wireless mode.
Note: One wireless mode can be selected can select at any one time. This means that you can
only select one of the operating frequency at a time.
Wireless Mode options
2.4GHz 802.11b/g mixed mode - This wireless mode works in the 2.4GHz frequency range
and will allow both wireless b and wireless g client to connect and access the TEW-639GR at
11Mbps for wireless b, at 54Mbps for wireless g and share access at the same time. Although
the wireless b/g operates in the 2.4GHz frequency, it will allow the use of other 2.4GHz client
devices (Wireless n/g @ 54Mbps) to connect and access at the same time.
2.4GHz 802.11 n only – This wireless mode works in the 2.4GHz frequency range and will
only allow the use of wireless n client devices to connect and access the TEW-639GR up to
300Mbps*. Although the wireless n operates in the 2.4GHz frequency, this mode will only
permit wireless n client devices to work and will exclude any other wireless mode and devices
that are not wireless n only.
2.4 GHz 802.11b/g/n mixed mode - This wireless mode works in the 2.4GHz frequency range
and will only allow the use of wireless g client devices to connect and access the TEW-639GR
at 11Mbps for wireless b, 54Mbps for wireless g and up to 300Mbps* for wireless n and share
access at the same time. Although the wireless b/g/n operates in the same 2.4GHz frequency,
it will allow the use of other 2.4GHz client devices (Wireless b/g/n) to connect and access at
the same time.
*Maximum wireless signal rates are referenced from IEEE 802.11 theoretical specifications. Actual data throughput
and coverage will vary depending on interference, network traffic, building materials and other conditions.
Wireless Network Name (SSID)
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. Add up to three additional SSIDs to create virtual wireless networks from one
wireless Router Access Point device.
Add Additional Wireless Network Name (SSID)
To add additional wireless Network Names simply add the name to the Multiple SSID field and
click on apply at the bottom of the page. When finished, go to the Security section in this Users
Guide for wireless security configuration.
Frequency (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.
Wireless Distribution System (WDS)
When WDS is enabled, this access point functions as a wireless repeater and is able to
wirelessly communicate with other APs via WDS links. 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.
22
(Note that WDS security is incompatible with mixed mode, like WPAPSK+WPA2PSK mixed,
WEP AUTO and 802.1x, both feature cannot be used at the same time).
Configuring WDS with TEW-639GR
Enable the option for WDS and input the MAC Address of the wireless device that also
supports WDS in to the blank fields. You can add up to four additional devices in the spaces
provided. Click on apply at the bottom of the page, to apply your setting changes.
Enable the security seeing in security page, each WDS APs need to use same security setting.
(Note: WDS supports wireless g/n modes. The use multiple Access Point will reduces the
overall network throughput to ½ the TEW-639GR.
HT Physical Mode
In HT (High Throughput) Physical mode setting allow for control of the 802.11n wireless
environment.

Mixed Mode
Green Field
Mixed Mode: In this mode packets are transmitted with a preamble compatible with the legacy
802.11a/g, the rest of the packet has a new format. In this mode the receiver shall be able to
decode both the Mixed Mode packets and legacy packets.
Green Field: In this mode high throughput packets are transmitted without a legacy compatible
part.
Channel BandWidth:
Set channel width of wireless radio.

20 Channel Width = 20 MHz
20/40 Channel Width = 20/40 MHz
Guard Interval:
Support Short/Long GI, the purpose of the guard interval is to introduce immunity to
propagation delays, echoes and reflections, to which digital data is normally very sensitive.
Long
Auto
Long Guard Interval, 800 nsec
Short Guard Interval, 400 nsec
MCS:
Fix MCS rate for HT rate.
0-15
The Modulation and Coding Scheme (MCS) is a value that determines the modulation, coding
and number of spatial channels.
23
4.2.2 Wireless: Advanced
Beacon Interval
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.
DTIM
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.
Fragmentation Threshold
Wireless frames can be divided into smaller units (fragments) to improve performance in the
presence of RF interference and at the limits of RF coverage. Fragmentation will occur when
frame size in bytes is greater than the Fragmentation Threshold. This setting should remain at
its default value of 2346 bytes. Setting the Fragmentation value too low may result in poor
performance.
RTS Threshold
When an excessive number of wireless packet collisions are occurring, wireless performance
can be improved by using the RTS/CTS (Request to Send/Clear to Send) handshake protocol.
The wireless transmitter will begin to send RTS frames (and wait for CTS) when data frame
size in bytes is greater than the RTS Threshold. This setting should remain at its default value
of 2346 bytes.
Short Preamble and Slot
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.
24
TX Burst
Allows the wireless Router to deliver better throughput in the same period and environment in
order to increase speed.
Pkt_Aggregate
Increase efficiency by aggregating multiple packets of application data into a single
transmission frame. In this way, 802.11n networks can send multiple data packets with the
fixed overhead cost of just a single frame.
25
4.2.3 Wireless: Security
Security Mode
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.
Key Length Hex ASCII
64-bit 10 characters 5 characters
128-bit 26 characters 13 characters
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 "WPA2" option, the router tries WPA2 first, but falls
back to WPA if the client only supports WPA. With the "WPA2 Only" option, the router
associates only with clients that also support WPA2 security.
26
Cipher Type: The encryption algorithm used to secure the data communication. TKIP
(Temporal Key Integrity Protocol) provides per-packet key generation and is based on WEP.
AES (Advanced Encryption Standard) is a very secure block based encryption. With the "TKIP
and AES" option, the router negotiates the cipher type with the client, and uses AES when
available.
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.
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.
WPA/WPA2 mixed environment
For those WPA2 stations, they will use AES for unicast. For those WPA stations, they will use
TKIP for unicast. But for multicast all WPA and WPA2 stations have to use the same key, and
that will be TKIP, because WPA station only knows about TKIP, WPA2 is new standard, so it
is defined to backward support TKIP on multicast.
Wireless MAC Filtering
Choose the type of MAC filtering needed.
Turn MAC Filtering Disable: When "Disable" is selected, MAC addresses are not used to
control network access.
Add MAC Filtering Rule
Use this section to add MAC addresses to the list below.
MAC Address
Enter the MAC address of a computer that you want to control with MAC filtering. Computers
that have obtained an IP address from the router's DHCP server will be in the DHCP Client List.
Select a device from the drop down menu.
The rule of thumb:
In mixed mode, multicast key has to be TKIP, but unicast key can be different per stations.
In WPA or WPA2 only mode, unicast and multicast key can be only AES for WPA2, and TKIP
for WPA. (AES means the unicast and multicast key are all AES. TKIP/AES means multicast
is TKIP. But unicast can be AES or TKIP, which depends on the peer.)

4.2.4 Wireless: WPS
28
Enable
Enable the WPS 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 WPS.
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 To WPS 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.
PBC Settings
The push button method can be used to allow wireless clients to connect to the router without
entering/remember any encryption keys. The user can use the PBC method by pressing the
WPS button on the side of the router or select the PBC option under Wireless/WPS settings
page and hit Apply.

4.3 Advanced
4.3.1 Advanced: DMZ
DMZ Setting
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 cyberattacks 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).
31
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
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.
