Static Routes

Static routes provide additional routing information to your router. Under usual

circumstances, the router has adequate routing information after it has been configured for

Internet access, and you do not need to configure additional static routes. You have to

configure static routes only for unusual cases such as multiple routers or multiple IP subnets

located on your network.

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 forwards your request to the ISP. The ISP

forwards your request to the company where you are employed, and the request is likely to

be denied by the company’s firewall.

In this case you have to define a static route, telling your router that 134.177.0.0 should be

accessed through the ISDN router at 192.168.1.100. 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 field 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.



To set up a static route:

1.

Select

Advanced > Advanced Setup > Static Routes

, and click

Add

to display the

following screen:

2.

In the Route Name field, type a name for this static route (for identification purposes only.)

3.

Select the

Private

check box if you want to limit access to the LAN only. If Private is

selected, the static route is not reported in RIP.

4.

Select the

Active

check box to make this route effective.

5.

Type the 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 has to be a router on the same LAN segment as the

N300 Wireless Router.

8.

Type a number between 1 and 15 as the metric value.

This value 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 add the static route.

Remote Management

The remote management feature lets you upgrade or check the status of your N300 Wireless

Router over the Internet.



To set up remote management:

1.

Select

Advanced > Advanced Setup > Remote Management

.

Note:

Be sure to change the router’s default login password to a very secure

password. The ideal password should contain no dictionary words from any

language and contain uppercase and lowercase letters, numbers, and

symbols. It can be up to 30 characters.

2.

Select the

Turn Remote Management On

check box.

3.

Under Allow Remote Access By, specify the external IP addresses to be allowed to access

the router’s remote management.

Note:

For enhanced security, restrict access to as few external IP addresses

as practical.

•

To allow access from a single IP address on the Internet, select

Only This Computer

.

Enter the IP address that will be allowed access.

•

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.

•

To allow access from any IP address on the Internet, select

Everyone

.

4.

Specify the port number for accessing the management interface.

Normal web browser access uses the standard HTTP service port 80. For greater

security, enter a custom port number for the remote web management 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.

5.

Click

Apply

to have your changes take effect.

6.

When accessing your router from the Internet, type your router’s WAN IP address into your

browser’s address or location field 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, enter

in your browser.

USB Settings

For added security, the router can be set up to share only approved USB devices. See

Specify Approved USB Devices

on page 52 for the procedure.

Universal Plug and Play

Universal Plug and Play (UPnP) helps devices, such as Internet appliances and computers,

to 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.

Note:

If you use applications such as multiplayer gaming, peer-to-peer

connections, or real-time communications such as instant

messaging or remote assistance (a feature in Windows XP), you

should enable UPnP.

To turn on Universal Plug and Play:

1.

Select

Advanced > Advanced Setup >

UPnP

. The UPnP screen displays.

2.

The available settings and information in this screen are:

Turn UPnP On

.

UPnP can be enabled or disabled for automatic device configuration.

The default setting for UPnP is disabled. If this check box is not selected, the router does

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 broadcasts 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 can compromise the freshness of

the device status, but can significantly reduce network traffic.

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 might be

necessary to increase this value.

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

whether that port is still active for each IP address.
