Wireless-G VPN Broadband Router

The Setup Tab - Advanced Routing

The

Advanced Routing

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

Advanced Routing

Operating Mode

. Select

Gateway

or

Router

from the drop-down menu. If this Router is hosting your network’s

connection to the Internet, keep the default,

Gateway

. If you have a different router hosting your Internet

connection, then select

Router

.

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

Enabled

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:

RIPv1

,

RIPv2-Broadcast

, or

RIPv2-Multicast

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

None

.

Static Routing

If the Router 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 Number

. Select the

number

of the static route from the drop-down menu. The Router supports up to

20 static route entries.

Delete This Entry

. If you need to delete a route, select its number from the drop-down menu, and click the

Delete This Entry

button.

LAN IP Address

. The LAN 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. For

example, the Router’s standard IP address is 192.168.1.1. Based on this address, the address of the routed

Figure 6-9: Setup Tab - Advanced Routing

Chapter 6: Configuring the Wireless-G VPN Broadband Router

The Setup Tab - Advanced Routing

Wireless-G VPN Broadband Router

network is 192.168.1, with the last digit determining the Router’s place on the network. Therefore you would

enter the IP address 192.168.1.0 if you wanted to route to the Router’s entire network, rather than just to the

Router.

Subnet Mask

. The Subnet Mask (also known as the Network Mask) determines which portion of an IP

address is the network portion, and which portion is the host portion. Take, for example, a network in which

the Subnet Mask is 255.255.255.0. This determines (by using the values 255) that the first three numbers of a

network IP address identify this particular network, while the last digit (from 1 to 254) identifies the specific

host.

Default Gateway

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

the remote network or host.

metric

. This determines the maximum number of steps between network nodes that data packets will travel.

A node is any device on the network, such as PCs, print servers, routers, etc.

Interface

. Select

LAN

& Wireless

or

Internet (WAN)

, depending on the location of the static route’s final

destination.

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

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

Wireless Network

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

.

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-g

) 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

Wireless-G VPN Broadband Router

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, 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 four are discussed here.

Select the appropriate security mode for your network. For detailed instructions on configuring wireless security

for the Router, turn to “Appendix B: Wireless Security.”

WPA Pre-Shared Key

. WPA gives you one encryption method, TKIP, with dynamic encryption keys. Select

TKIP

or

AES

from the

WPA Algorithm

drop-down menu. Enter a WPA Shared Key of 8-32 characters. Then enter the Key

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

Save Settings

button to save the changes, or

click the

button to undo your changes. Help information is shown on the right-hand side of a

screen. For additional information, click

.

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.) Enter the RADIUS server’s IP address. Select

TKIP

or

AES

from

the

WPA Algorithm

drop-down menu. Enter the RADIUS server’s port number, along with the Shared Secret key,

which is the key shared between the Router and the server. Last, enter the Key Renewal Timeout period, which

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