Dynamic DNS
If your Internet service provider (ISP) gav e you a permanently assigned IP address, you can 
register a domain name and have that name linked with your IP address by public Domain 
Name Servers (DNS). However, if your Inte rnet account uses a dynamically assigned IP 
address, you do not know in advance what  your IP address will be, and the address can 
change frequently. In this case, you can use a  commercial Dynamic DNS service. This type 
of service lets you register your domain to th eir IP address and 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 will not
  work because private addresses are not routed on the Internet.
Your router contains a client that can con nect
  to the Dynamic DNS service provided by 
DynDNS.org. First visit their website at  http://www.dyndns.org and obtain an account and

N900 Wireless Dual Band Gigabit Router WNDR4500 
host name that you configure in the router. Then, whenever your ISP-assigned IP address 
changes, your router automatically contacts the Dynamic DNS service provider, logs in to 
your account, and registers your new IP address. If your host name is hostname, for 
example, you can reach your router at 
http://hostname.dyndns.org.
On the Advanced tab, select  Advanced Setup >
  Dynamic DNS to display the following 
screen:

To set up Dynamic DNS:
1. Register for an  account with
  one of the Dynamic DNS service providers whose names 
appear in the Service Provider list. For example, for DynDNS.org, select 
www.dyndns.org .
2. Select the  Use a Dynami
 c DNS Service check box. 
3. Select the name of your  Dynamic 
 DNS service provider. 
4. Type the host name (or domain name) that your Dynamic DNS service provider gave you.
5. Type the user name for your Dynamic DNS account. This is the name that you use to log in 
to
  your account, not your host name.
6. Type the password (or key) for your Dynamic DNS account. 
7. If your Dynamic DNS provider allows the use of wildcards in resolving your URL, you can 
select the  Use W

ildcards check box to activate this feature. 
For example, the wildcard feature causes  *.yourh
 ost.dyndns.org to be aliased to the 
same IP address as yourhost.dyndns.org.

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:
•
Y
our primary Internet access is through a cable modem to an ISP.
•Y
ou 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.
• Y
our 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 cre

ated 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 th is 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,  t
 elling your router that 134.177.0.0 should be 
accessed through the ISDN router at 192.168.1.100. In this example:
• T
he Destination IP Address and IP Subnet Mask  fields specify that this static route 
applies to all 134.177.x.x addresses. 
• T
he 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 se curity 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  Privat
 e 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 ef
 fective. 
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 has to be a router on the same LAN segment as the 
N900 Wirele
 ss Dual Band Gigabit Router. 
8. Type a number between 1 and 15 as the metric value. 
This va
 lue 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 ad

d the static route.

Normal web browser access uses the standard HTTP service port 80. For greater 
security, enter a custom port number for the remote web management nterface. 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. Wh
en accessing your router from the Internet, ty pe 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 
http://134.177.0.123:8080  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  o
 n page 50  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 ot her devices as needed. UPnP devices can 
automatically discover the se rvices 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. 
						

							Advanced Settings107
 N900 Wireless Dual Band Gigabit Router WNDR4500
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:
Tu r n  U P n P  O n . UPn P
  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  adve
 rtisement period is how often the router broadcasts its 
UPnP information. This value can range fr om 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 t

o 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, whic h 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 Port
 map 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.
