3.

In the Allow Remote Access By section, specify the external IP addresses to be allowed to

access the router’s remote management, as follows:

•

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

.

Note:

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

as practical.

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 from 1024 to 65535, but do not use the number of any common service port.

The default is 8080, which is a common alternate for HTTP.

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.

Universal Plug and Play

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.

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 enable Universal Plug and Play:

1.

Select

Advanced > Advanced Setup >

UPnP

.

The UPnP screen displays.

2.

Configure the UPnP settings, as follows:

•

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 is 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.

•

Download only

. The restriction is applied to incoming traffic only.

•

Both Directions

. The restriction is applied to both incoming and outgoing traffic.

4.

To limit the amount of data traffic allowed per month, specify how many Mbytes per month

are allowed or specify how many hours of traffic are allowed.

5.

Set the Traffic Counter to begin at a specific time and date.

6.

Set up Traffic Control to issue a warning message before the monthly limit of Mbytes or

hours is reached.

You can select one of the following to occur when the limit is attained:

•

The Internet LED flashes green.

•

The Internet connection is disconnected and disabled.

7.

Set up Internet Traffic Statistics to monitor the data traffic.

Quick Tips

This section describes tips for troubleshooting some common problems

Sequence to Restart Your Network

Be sure to restart your network in this sequence:

1.

Turn off

and

unplug the modem.

2.

Turn off the router and computers.

3.

Plug in the modem and turn it on. Wait 2 minutes.

4.

Turn on the router and wait 2 minutes.

5.

Turn on the computers.

Check Ethernet Cable Connections

Make sure that the Ethernet cables are securely plugged in.

The Internet LED on the router is on if the Ethernet cable connecting the router and the

modem is plugged in securely and the modem and router are turned on.

For each powered-on computer connected to the router by an Ethernet cable, the

corresponding numbered router LAN port LED is on.

Wireless Settings

Make sure that the wireless settings in the computer and router match exactly.

For a wirelessly connected computer, the wireless network name (SSID) and wireless

security settings of the router and wireless computer must match exactly.

If you set up an access list in the Advanced Wireless Settings screen, you must add each

wireless computer’s MAC address to the router’s access list.

Network Settings

Make sure that the network settings of the computer are correct.

Wired and wirelessly connected computers must have network (IP) addresses on the same

network as the router. The simplest method is to configure each computer to obtain an IP

address automatically using DHCP.

Some cable modem service providers require you to use the MAC address of the computer

initially registered on the account. You can view the MAC address in the Attached Devices

screen.
