Dynamic DNS
If your Internet service provider (ISP) gave 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 Internet account uses a dynamically assigned IP
address, you do not know in advance what your IP address is, 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 their 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 does not works because private addresses are not routed on the Internet.
Your WiFi modem router contains a client that can connect to the Dynamic DNS service
provided by DynDNS.org. First visit their website at
and obtain an
account and host name that you configure in the WiFi modem router. Then, whenever your
ISP-assigned IP address changes, your WiFi modem 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 WiFi modem router at
On the Advanced tab, select

1.
Register for an account with one of the Dynamic DNS service providers whose
addresses appear in the Service Provider list.
2.
Select the

check box.
3.
Select the address of your Dynamic DNS service provider. For example, for DynDNS.org,
select
www.dyndns.org
.
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.

Static Routes
Static routes provide additional routing information to your WiFi modem router. Under usual
circumstances, the WiFi modem 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 WiFi modem routers
or multiple IP subnets on your network.
As an example of when a static route is needed, consider the following case:
Page 113 / 142

•
Your primary Internet access is through a cable modem to an ISP.
•
You have an ISDN WiFi modem router on your home network for connecting to the
company where you are employed. This WiFi modem 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 WiFi 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 192.168.1.x addresses. With this configuration, if you
attempt to access a device on the 134.177.0.0 network, your WiFi 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 WiFi modem router that 134.177.0.0
should be accessed through the ISDN WiFi modem 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 WiFi modem router at 192.168.1.100.
•
A metric value of 1 works since the ISDN WiFi 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
to display the following screen:

2.
Click
Add
to display the following screen:
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 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 a WiFi modem router on the same LAN
segment as the WiFi DSL Modem Router.
9.
Type a number from 1 through 15 as the metric value.
This value represents the number of WiFi modem routers between your network and the
destination. Usually, a setting of 2 or 3 works, but if this link is a direct connection, set it to
1.
10.
Click
Apply
to add the static route.

Remote Management
The remote management feature lets you upgrade or check the status of your WiFi DSL
Modem Router over the Internet.
To set up remote management:
1.
Select
ADVANCED > Advanced Setup > Remote Management
.
Note:
Be sure to change the WiFi modem 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 WiFi modem router’s remote web management interface.
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 is 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 web management interface.
