Set Up a Wireless Access List by MAC Address
You can set up a list of computers and wireless devices that are allowed \
to join the wireless  network. This list is based on the unique MAC address of each computer and device\
.
Each network device has a MAC address, which is a unique 12-character ph\
ysical address, 
containing the hexadecimal characters 0–9, a–f, or 
 A–F only, and separated by colons (for 
example, 00:09:AB:CD:EF:01). Typically, the MAC address is on the label of the wireless 
card or network interface device. If you do not have access to the label\
, you can display the 
MAC address using the network configuration utilities of the computer. You might also find 
the MAC addresses in the Attached Devices screen.
To restrict access based on MAC addresses:

recommends that you use a different wireless channel.
6.  Click  Apply .
The IP address of the modem router changes and you are disconnected. To reconnect,  close and restart your web browser
 , and type http://www.routerlogin.net .
Dynamic DNS
If your ISP assigned you a fixed IP address, you can register a domain n\
ame and link it to 
your IP address by public DNS. However, most Internet accounts use dynamically assigned 
IP addresses that can change frequently. In this case, you can use a commercial Dynamic 
DNS service. This type of service lets you register your domain to their IP address a\
nd 
forwards traffic directed at your domain to your frequently changing IP address.
If your ISP assigns a private WAN IP address (such as 192.168.x.x or 10.x.x.x), the Dynamic 
DNS service does not work because private addresses are not routed on th\
e Internet.
Your modem router contains a client that can connect to the Dynamic DNS s\
ervice provided  by DynDNS.org. First visit their website at  http://www

.dyndns.org and obtain an account and 
host name that you configure in the modem router. Then, whenever your ISP-assigned IP 
address changes, your modem router automatically contacts the Dynamic DN\
S service 
provider, logs in to your account, and registers your new IP address. If your ho\
st name is 
hostname, for example, you can reach your modem router at http://hostnam\
e.dyndns.org.
To set up Dynamic DNS:
1.  Select  Advanced > 
 Advanced Setup > Dynamic DNS.
2. Register for an account with one of the Dynamic DNS service providers wh\
ose URLs are in 
the Service Provider list. 
For example, for DynDNS.org, select www
 .dyndns.org.
3.  Select the  Use a Dynamic DNS Service  check box. 
4.  Select the URL of your Dynamic DNS service provider
 . 
5.  T
ype the host name (or domain name) that your Dynamic DNS service provi\
der gave you.
6. T
ype the user name for your Dynamic DNS account. 
This is the name that you use to log in to your account, not your host n\
ame.

Static Routes
Static routes provide more routing information to your modem router. Typically, you do not 
need to add static routes. You have to configure static routes only for unusual cases such as 
multiple modem routers or multiple IP subnets on your network.
As an example of when a static route is needed, consider the following c\
ase: • Y
our primary Internet access is through a cable modem to an ISP.
•Y
ou have an ISDN modem router on your home network for connecting to the \
company 
where you are employed. This modem router’s address on your LAN is 192.168.0.100.
• Y
our company’s network address is 134.177.0.0.
When you first configured your modem 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 192.168.0.x addresses. With this c\
onfiguration, if you 
attempt to access a device on the 134.177.0.0 network, your modem 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 modem route\
r that 134.177.0.0 
should be accessed through the ISDN modem router at 192.168.0.100. In th\
is 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 modem router at 192.168.0.100. 
• A metric value of 1 works because the ISDN modem 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.
2.  Click  Add. 
						

							Advanced Settings 
88 N300 Wireless ADSL2+ Modem Router DGN2200v4 
3. In the Route Name field, type a name for this static route (for identification purposes only.) 
4. 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. 
5. Select the Active check box to make this route effective. 
6. Type the destination IP address of the final destination. 
7. Type the IP subnet mask for this destination. If the destination is a single host, type 
255.255.255.255. 
8. Type the gateway IP address, which has to be on the same LAN segment as the modem 
router. 
9. Type a number from 1 through 15 as the metric value. 
This value represents the number of modem 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. 
10. Click Apply 
The static route is added. 
To edit or delete a static route:
1. Select Advanced > Advanced Setup > Static Routes.
The Static Routes screen displays.
2. In the table, select the radio button next to the route that you want to edit or delete.
3. Do one of the following:
•Click the Edit button.
The Static Routes screen adjusts.
a.Edit the route information.
b. Click the Apply button.
•Click the Delete button.
The route is removed from the table.
Remote Management
The remote management feature lets you upgrade or check the status of your modem router 
over the Internet.
Note:Be sure to change the modem router default login password to a 
secure password. The ideal password contains no dictionary words 
from any language and contains uppercase and lowercase letters, 
numbers, and symbols. It can be up to 30 characters.

To set up remote management:
1. 
Select  Advanced > 
 Advanced Setup > Remote Management. 
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  modem router’s  remote management.
For enhanced security, restrict access to as few external IP addresses as practical.
• T
o allow access from a single IP address on the Internet, select Only This 
Computer . Enter the IP address that will be allowed access. 
• T
o 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. 
• T
o specify IP addresses, select IP Address List  and type in the allowed IP 
addresses. 
• T
o allow access from any IP address on the Internet, select Everyone . 
4.  Specify the port number for accessing the web management interface.
Normal web browser access uses the standard HTTP service port 80. For gr\
eater 
security
 , enter a custom port number for the remote web management interface. Ch\
oose 
a number from 1024 to 65535, but do not use the number of any common ser\
vice port. 
The default is 8080, which is a common alternate for HTTP.
5.  Click  Apply .
Your changes take effect.
6.  When you access your modem router from the Internet, type your modem rou\
ter’
 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 http://134.177.0.123:8080 in your browser

Universal Plug and Play
Universal Plug and Play (UPnP) helps devices, such as Internet applian\
ces and computers, 
access the network and connect to other devices as needed. UPnP devices \
can 
automatically discover the services from other registered UPnP devices o\
n the network.
If you use applications such as multiplayer gaming, peer-to-peer connect\
ions, or real-time 
communications such as instant messaging or remote assistance (a featur\
e in Windows XP), 
you should enable UPnP

.
To turn on Universal Plug and Play:
1. Select  Advanced > 
 Advanced Setup > UPnP. 
2. Select the Turn UPnP On check box.
By default, this check box is selected. UPnP for automatic device config\
uration can 
be enabled or disabled. If the T
 urn UPnP On check box is cleared, the  modem router 
does not allow any device to automatically control the resources, such a\
s port 
forwarding (mapping), of the modem router.
3.  T
ype the advertisement period in minutes.
The advertisement period specifies how often the modem router broadcasts its 
UPnP information. This value can range from 1 to 1440 minutes. The defau\
lt period 
is 30 minutes. Shorter durations ensure that control points have current\
 device 
status at the expense of additional network traffic. Longer durations ca\
n 
compromise the freshness of the device status, but can significantly red\
uce 
network traffic.
4.  T
ype the advertisement time to live in hops.
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 broadca\
st 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 advert\
isement 
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

, it might be 
necessary to increase this value.
5.  Click the 
 Apply button.
The UPnP Portmap Table displays the IP address of each UPnP device that is 
accessing the modem router. The UPnP Portmap T
 able also shows which ports are
