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

Chapter 6: Configuring the Wireless-G VPN Broadband Router

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
Close
button to exit this screen.

The Wireless Tab - Basic Wireless Settings
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

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.
When you have finished making changes to the screen, click the
Save Settings
button to save the changes, or
click the
Cancel Changes
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.
