3.
Select
Private
if you want to limit access to the LAN only. The static route will not be
reported in RIP.
4.
Select
Active
to make this route effective.
5.
Type the Destination IP Address of the final destination.
6.
Type the IP Subnet Mask for this destination.
If the destination is a single host, type 255.255.255.255.
7.
Type the Gateway IP Address, which must be a router on the same LAN segment as the
WNR834M.
8.
Type a number between 1 and 15 as the Metric value.
This represents the number of routers between your network and the destination. Usually, a
setting of 2 or 3 works, but if this is a direct connection, set it to 1.
9.
Click
Apply
to have the static route entered into the table.
As an example of when a static route is needed, consider the following case:
Your primary Internet access is through a cable modem to an ISP.
You have an ISDN router on your home network for connecting to the company where
you are employed. This router’s address on your LAN is 192.168.1.100.
Your company’s network address is 134.177.0.0.
When you first configured your router, two implicit static routes were created. A default route was
created with your ISP as the gateway, and a second static route was created to your local network
for all 192.168.1.x addresses. With this configuration, if you attempt to access a device on the
134.177.0.0 network, your router will forward your request to the ISP. The ISP forwards your
request to the company where you are employed, and the request will likely be denied by the
company’s firewall.
In this case you must define a static route, telling your router that 134.177.0.0 should be accessed
through the ISDN router at 192.168.1.100. The static route would look like
Figure 6-12
.
In this example:
The Destination IP Address and IP Subnet Mask fields specify that this static route applies to
all 134.177.x.x addresses.
The Gateway IP Address fields specifies that all traffic for these addresses should be
forwarded to the ISDN router at 192.168.1.100.
A Metric value of 1 will work since the ISDN router is on the LAN.
Private is selected only as a precautionary security measure in case RIP is activated.

Enabling Remote Management Access
Using the Remote Management page, you can allow a user or users on the Internet to configure,
upgrade and check the status of your WNR834M router.
To configure your router for Remote Management:
1.
Select the
Turn Remote Management On
check box.
2.
Specify what external addresses will be allowed to access the router’s remote management.
Figure 6-13
Note:
Be sure to change the router's default configuration password to a very secure
password. The ideal password should contain no dictionary words from any
language, and should be a mixture of letters (both upper and lower case), numbers,
and symbols. Your password can be up to 30 characters.
Note:
For enhanced security, restrict access to as few external IP addresses as
practical.

a.
To allow access from any IP address on the Internet, select
Everyone
.
b.
To allow access from a range of IP addresses on the Internet, select
IP address range
.
Enter a beginning and ending IP address to define the allowed range.
c.
To allow access from a single IP address on the Internet, select
Only this computer
.
Enter the IP address that will be allowed access.
3.
Specify the Port Number for accessing the management interface.
Web browser access normally uses the standard HTTP service port 80. For greater security,
enter a custom port number for the remote management Web interface. Choose a number
between 1024 and 65535, but do not use the number of any common service port. The default
is 8080, which is a common alternate for HTTP.
4.
Click
Apply
to have your changes take effect.
Note:
When accessing your router from the Internet, type your router's WAN IP address
into your browser's Address (in Internet Explorer) or Location (in Netscape) box,
followed by a colon (:) and the custom port number. For example, if your external
address is 134.177.0.123 and you use port number 8080, then enter http://
134.177.0.123:8080 in your browser.

Using Universal Plug and Play (UPnP)
Universal Plug and Play (UPnP) helps devices, such as Internet appliances and computers, access
the network and connect to other devices as needed. UPnP devices can automatically discover the
services from other registered UPnP devices on the network.
From the main menu of the browser interface, under Advanced, click on
UPnP
. Set up UPnP
according to the guidelines below.
Turn UPnP On—
UPnP can be enabled or disabled for automatic device configuration. The
default setting for UPnP is disabled. If disabled, the router will not allow any device to
automatically control the resources, such as port forwarding (mapping) of the router.
Advertisement Period
—the Advertisement Period is how often the router will broadcast its UPnP
information. This value can range from 1 to 1440 minutes. The default period is 30 minutes.
Shorter durations ensure that control points have current device status at the expense of additional
network traffic. Longer durations may compromise the freshness of the device status but can
significantly reduce network traffic.
Figure 6-14
Note:
If you use applications such as multi-player gaming, peer-to-peer connections, real
time communications such as instant messaging, or remote assistance (a feature in
Windows XP), you should enable UPnP.

Advertisement Time To Live
—the time to live for the advertisement is measured in hops (steps)
for each UPnP packet sent. The time to live hop count is the number of steps a broadcast packet is
allowed to propagate for each UPnP advertisement before it disappears. The number of hops can
range from 1 to 255. The default value for the advertisement time to live is 4 hops, which should
be fine for most home networks. If you notice that some devices are not being updated or reached
correctly, then it may be necessary to increase this value a little.
UPnP Portmap Table
—the UPnP Portmap Table displays the IP address of each UPnP device
that is currently accessing the router and which ports (Internal and External) that device has
opened. The UPnP Portmap Table also displays what type of port is open and if that port is still
active for each IP address.
