The Router 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 Router. Before you can use this feature, you need to sign up for DDNS service at

www.dyndns.org, a DDNS service providers.

DDNS Service

. From this pull-down menu, enter the DDNS service with which you have membership.

User Name

. Enter the User Name for your DDNS account

Password

. Enter the Password for your DDNS account.

Host Name

. The is the DDNS URL assigned by the DDNS service.

Internet IP Address

. This is the Router’s current IP Address as seen on the Internet.

Status

. This displays the status of the DDNS connection.

The Setup Tab - MAC Address Clone

A MAC address is a 12-digit code assigned to a unique piece of hardware for identification. Some ISPs will

require you to register a MAC address in order to access the Internet.

If you do not wish to re-register the MAC

address with your ISP, you may assign the MAC address you have currently registered with your ISP to the Router

with the MAC Address Clone feature.

Enable/Disable

. To have the MAC Address cloned, click the radio button beside

Enable

.

User Defined Entry

. Enter the MAC Address registered with your ISP here.

Clone Your PC’s MAC

. Clicking this button will clone the MAC address.

The Setup Tab - Advanced Routing

Wireless-G Broadband Router with SRX

The Setup Tab - Advanced Routing

This tab is used to set up the Router’s advanced functions. NAT Mode allows you to select the type(s) of advanced

functions you use. Static Routing sets up a fixed route to another network destination.

NAT Mode

. Select the mode in which this Router will function. If this Router is hosting your network’s connection

to the Internet, select

Enable

. If another Router exists on your network, select

Disable

.

Dynamic Routing

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

in the network’s layout. The Router, using the RIP protocol, 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 routers on the network.

RIP

. To use dynamic routing, click the

Disabled

radio button.

Receive RIP Version

. To use dynamic routing for reception of network data, select the protocol you want:

Both RIP v1 and v2

,

RIPv1

, or

RIPv2

. If you do not want to use this feature, select

None

.

Transmit RIP Version

. To use dynamic routing for transmission of network data, select the protocol you

want:

Both RIP v1 and v2

,

RIPv1

, or

RIPv2

. If you do not want to use this feature, select

None

.

Static Routing

. To set up a static route between the Router and another network, select a number from the

Static

Routing

drop-down list. (A static route is a pre-determined pathway that network information must travel to reach

a specific host or network.) Enter the information described below to set up a new static route. (Click the

Delete

This Entry

button to delete a static route.)

Enter Route Name

. Enter a name for the Route here, using a maximum of 25 alphanumeric characters.

Destination LAN IP

. The Destination LAN IP is the address of the remote network or host to which you want to

assign a static route.

Subnet Mask

. The Subnet Mask determines which portion of a Destination LAN IP address is the network

portion, and which portion is the host portion.

Default Gateway

. This is the IP address of the gateway device that allows for contact between the Router and

the remote network or host.

Interface

. This interface tells you whether the Destination IP Address is on the

LAN & Wireless

(Ethernet and

wireless networks), the

WAN

(Internet), or

Loopback

(a dummy network in which one PC acts like a

network—necessary for certain software programs).

The Wireless Tab - Basic Wireless Settings

The basic settings for wireless networking are set on this screen.

Wireless Network Mode

. From this drop-down menu, you can select the wireless standards running on your

network. If you have both 802.11g and 802.11b devices in your network, keep the default setting,

Mixed

. If you

have only 802.11g devices, select

G-Only

. If you have only 802.11b devices, select

B-Only

. If you do not have any

802.11g and 802.11b devices in your network, select

Disable

. SRX works automatically with all settings,

providing the added bonus of increased speed across your entire network and even greater speed when using

SRX products only.

Wireless Network Name (SSID)

. The SSID is the network name shared among all points in a wireless network.

The SSID must be identical for all devices in the wireless network. It is case-sensitive and must not exceed 32

characters (use any of the characters on the keyboard). Make sure this setting is the same for all points in your

wireless network. For added security, you should change the default SSID (

linksys

) to a unique name.

Wireless Channel

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

settings. All devices in your wireless network must be broadcast on the same channel in order to function

correctly.

Wireless SSID Broadcast

. When wireless clients survey the local area for wireless networks to associate with,

they will detect the SSID broadcast by the Router. To broadcast the Router's SSID, keep the default setting,

Enable

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

Disable

.

QoS Configuration

. Quality of Service (QoS) ensures better service to high-priority types of network traffic,

which may involve demanding, real-time applications, such as videoconferencing.

ACK Mode

. This setting prioritizes QoS for users who also have ACK Mode enabled. Users with

Immediate ACK

(the default setting) will experience reliable connectivity for normal network use.

Burst ACK

is faster but less

reliable and may also affect long-range wireless performance. The

No ACK

setting disables the ACK feature.

Clients utilizing ACK must have their wireless adapter on the same setting as the Router.

802.11e QoS

. This setting prioritized QoS for uses who have this setting enabled on their wireless adapter.

The Wireless Tab - Wireless Security

Wireless-G Broadband Router with SRX

The Wireless Tab - Wireless Security

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

mode options supported by the Router: WPA Pre-Shared Key, WPA RADIUS, and WEP. (WPA stands for Wi-Fi

Protected Access, which is a security standard stronger than WEP encryption. WEP stands for Wired Equivalent

Privacy, while RADIUS stands for Remote Authentication Dial-In User Service.) These three are briefly discussed

here. For detailed instructions on configuring wireless security for the Router, turn to “Appendix B: Wireless

Security.”

WPA Pre-Shared Key

. WPA gives you two encryption methods, TKIP and AES, with dynamic encryption keys.

Select the type of algorithm,

TKIP

or

AES

. Enter a WPA Shared Key of 8-63 characters. Then enter a Group Key

Renewal period, which instructs the Router how often it should change the encryption keys.

WPA RADIUS

. This option features WPA used in coordination with a RADIUS server. (This should only be used

when a RADIUS server is connected to the Router.) First, select the type of WPA algorithm you want to use,

TKIP

or

AES

. Enter the RADIUS server’s IP Address and port number, along with a key shared between the Router and

the server. Last, enter a Key Renewal Timeout, which instructs the Router how often it should change the

encryption keys.

(WPA RADIUS)

IMPORTANT:

If you are using WPA, always

remember that each device in your wireless

network MUST use the same WPA method

and shared key, or else the network will not

function properly.
