The DDNS Tab

The Gateway offers a Dynamic Domain Name System (DDNS) feature. DDNS lets you assign a fixed host and

domain name to a dynamic Internet IP address. It is useful when you are hosting your own website, FTP server, or

other server behind the Gateway.

Before you can use this feature, you need to sign up for DDNS service at DynDNS.org or TZO.com.

DDNS Service. If your DDNS service is provided by DynDNS.org, then select

DynDNS.org

from the drop-down

menu. If your DDNS service is provided by TZO.com, then select

TZO.com

from the drop-down menu.To disable

DDNS Service, select

The Setup Tab

Home Wireless-G Gateway

The Advanced Routing Tab

The

Advanced Routing

screen allows you to configure the NAT, dynamic routing, and static routing settings.

Advanced Routing

•

Operating Mode. In this section, you will configure the Gateway’s general routing settings.

•

NAT. NAT is a security feature that is enabled by default. It enables the Gateway to translate IP addresses

of your local area network to a different IP address for the Internet. To disable NAT, click the

Disabled

radio button.

•

RIP. If you have multiple routers, you may want to use the Routing Information Protocol (RIP) so the routers

can exchange routing information with each other. To use RIP, select the

Enabled

radio button. Otherwise,

keep the default,

Disabled

.

•

Send Default Route. To use RIP version 1 for routing, select the

Enabled

radio button. Otherwise, keep the

default,

Disabled

.

•

Interface. This setting is available when you have configured a static route and you need to choose an

interface for that route. Select the interface that the Gateway will be using:

LAN

/

Wireless

or

Internet

.

•

Dynamic Routing. With Dynamic Routing you can enable the Gateway to automatically adjust to physical

changes in the network’s layout. Using RIP, the Gateway determines the network packets’ route based on the

fewest number of hops between the source and the destination. The RIP protocol regularly broadcasts routing

information to other Gateways on the network.

•

Transmit RIP Version. To transmit RIP messages, select the protocol you want:

RIP1, RIP1-Compatible,

or RIP2

. If you don’t want to transmit RIP messages, select

None

.

•

Receive RIP Version. To receive RIP messages, select the protocol you want:

RIP1

or

RIP2

. If you don’t

want to receive RIP messages, select

None

.

•

Multicast or Broadcast. RIP can be sent using either methods. If you want to use multicasting, select

Multicast

. If you want to use Broadcast, select

Broadcast

.

•

Static Routing. If the Gateway is connected to more than one network, it may be necessary to set up a static

route between them. A static route is a pre-determined pathway that network information must travel to

reach a specific host or network. To create a static route, change the following settings:

•

Select set number. Select the number of the static route from the drop-down menu. The Gateway

supports up to 20 static route entries. If you need to delete a route, then select the entry and click the

Delete This Entry

button.

•

Destination IP Address. The Destination IP Address is the address of the remote network or host to which

you want to assign a static route. Enter the IP address of the host for which you wish to create a static

route. If you are building a route to an entire network, be sure that the network portion of the IP address is

set to 0.

•

Subnet Mask. Enter the Subnet Mask (also known as the Network Mask), which determines which portion

of an IP address is the network portion, and which portion is the host portion.

•

Gateway. Enter the IP address of the gateway device that allows for contact between the Gateway and the

remote network or host.

•

Hop Count. Hop Count is the number of hops to each node until the destination is reached (16 hops

maximum). Enter the Hop Count in the field provided.

•

Show Routing Table. Click the

Show Routing Table

button to open a screen displaying how data is routed

through your local network. For each route, the Destination LAN IP address, Subnet Mask, Gateway, and

Interface are displayed. Click the

Refresh

button to update the information. Click the

Close

button to return to

the previous screen.

When finished making your changes on this tab, click the

The Basic Wireless Settings Tab

This screen allows you to choose your wireless network mode and wireless security.

Wireless Network

•

Wireless Network Mode. If you have 802.11g and 802.11b devices in your network, then keep the default

setting,

Mixed

. If you have only 802.11g devices, select

802.11g

. If you have only 802.11b devices, select

802.11b

. If you want to disable wireless networking, select

Disabled

.

•

Wireless Network Name (SSID). Enter the name for your wireless network into the field. The SSID is the

network name shared among all devices in a wireless network. It must be identical for all devices in the

wireless network. It is case-sensitive and must not exceed 32 alphanumeric characters, which may be any

keyboard character. Linksys recommends that you change the default SSID (linksys) to a unique name of your

choice.

•

Wireless Channel. Select the appropriate channel from the list provided to correspond with your network

settings. All devices in your wireless network must use the same channel in order to function correctly.

Wireless computers or clients will automatically detect the wireless channel of the Gateway.

•

Wireless SSID Broadcast. When wireless computers or clients survey the local area for wireless networks to

associate with, they will detect the SSID broadcast by the Gateway. To broadcast the Gateway's SSID, keep

the default setting,

Enable

. If you do not want to broadcast the Gateway's SSID, then select

Disable

.

The Wireless Security Tab

The Wireless Security settings configure the security of your wireless network. There are two wireless security

options supported by the Gateway: Pre-Shared Key and WEP. (Pre-Shared Key is a security standard stronger than

WEP (Wired Equivalent Privacy) encryption. These are briefly discussed here. For detailed instructions on

configuring wireless security for the Gateway, turn to “Appendix B: Wireless Security.” If you want to disable

wireless security, select

Disable

from the drop-down menu for Security Mode.

Pre-Shared Key. Enter a Pre-Shared Key of 8-32 characters. Then enter a Group Key Renewal period, which

instructs the Gateway how often it should change the encryption keys.
