If your Dynamic DNS provider allows the use of wildcards in resolving your URL, you can

select the

Use Wildcards

check box to activate this feature. For example, the wildcard

feature causes *.yourhost.dyndns.org to be aliased to the same IP address as

yourhost.dyndns.org.

Click

Apply

to save your settings.

Note:

If your ISP assigns a private WAN IP address such as 192.168.x.x

or 10.x.x.x, the Dynamic DNS service will not work because private

addresses are not routed on the Internet.

LAN Setup

The LAN Setup screen allows configuration of LAN IP services such as DHCP and Routing

Information Protocol (RIP). The wireless modem router is shipped preconfigured to use

private IP addresses on the LAN side and to act as a DHCP server. The wireless modem

router’s default LAN IP configuration is as follows:

•

LAN IP address

. 192.168.0.1

•

Subnet mask

. 255.255.255.0

These addresses are part of the private address range designated by the Internet

Engineering Task Force (IETF

http://www.ietf.org/

) for use in private networks, and should be

suitable in most applications. If your network has a requirement to use a different IP

addressing scheme, you can make those changes in the LAN IP Setup screen.

Note:

If you change the LAN IP address of the wireless modem router

while connected through the browser, you are disconnected. To

reconnect, open a new connection to the new IP address and log in.

Note:

The default DHCP and TCP/IP values work for most users.

•

Device Name

. This is an abbreviated name of the wireless modem router. You see

this name for the router in Network Explorer on Windows systems.

•

Use Auto IP

. Select this check box if you want the wireless modem router to set up

the

LAN IP

addresses automatically.

•

IP Address

. The LAN IP address of the wireless modem router.

•

IP Subnet Mask

. The LAN subnet mask of the wireless modem router. Combined

with the IP address, the IP subnet mask allows a device to know which other

addresses are local to it, and which have to be reached through a gateway or wireless

modem router.

•

Use Router as DHCP Server

. By default, the wireless modem router functions as a

Dynamic Host Configuration Protocol (DHCP) server, allowing it to assign IP, DNS

server, and default gateway addresses to all computers connected to the wireless

modem router’s LAN. The assigned default gateway address is the LAN address of

the router. IP addresses are assigned to the attached PCs from a pool of addresses

specified in this screen. Each pool address is tested before it is assigned to avoid

duplicate addresses on the LAN.

For most applications, the default DHCP and TCP/IP settings of the router are

satisfactory.

•

Reserved IP Addresses Setup

. When you specify a reserved IP address for a

computer on the LAN, that computer always receives the same IP address each time

it accesses the router’s DHCP server. Reserved IP addresses should be assigned to

servers that require permanent IP settings.



To reserve an IP address:

1.

Select

Advanced > LAN Setup

and click the

Add

button.

2.

In the

IP Address

field, type the IP address to assign to the computer or server. Choose an

IP address from the router’s LAN subnet, such as 192.168.0.x.

3.

Type the MAC address of the computer or server.

Tip:

If the computer is already present on your network, copy its MAC

address from the Attached Devices screen and paste it here.

4.

Click

Apply

to enter the reserved address into the table.

Note:

The reserved address is not assigned until the next time the

computer contacts the router’s DHCP server. Reboot the computer

or access its IP configuration to force a DHCP release and renew.



To edit or delete a reserved address entry:

1.

Select the radio button next to the reserved address that you want to edit or delete.

Set Up Quality of Service (QoS)

Quality of Service (QoS) is an advanced feature that can be used to prioritize some types of

traffic ahead of others. The modem router can provide QoS prioritization over the wireless

link and on the Internet connection.

The modem router supports Wi-Fi Multimedia Quality of Service (WMM QoS) to prioritize

wireless voice and video traffic over the wireless link. WMM QoS provides prioritization of

wireless data packets from different applications based on four access categories: voice,

video, best effort, and background. For an application to receive the benefits of WMM QoS,

both it and the client running that application

has to

be WMM enabled. Legacy applications

that do not support WMM, and applications that do not require QoS, are assigned to the best

effort category, which receives a lower priority than voice and video.
