N600 Wireless Dual Band Gigabit VDSL2 Modem Router DGND3800B
Web browser access usually uses the standard HTTP service port 80. For greater
security, you can change it so the remote router interface uses a custom port by entering
that number in the field provided. 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.

To access your modem router from the Internet, type your modem router’s WAN IP
address in your browser’s Address field, followed by a colon (:) and the custom port
number.
For example, if your external address is 134.177.0.123 at port number 8080, enter the
following in your browser:
http://134.177.0.123:8080
The http:// has to be included in the address.
Static Routes
Static routes provide additional routing information to your router. Under normal
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.
Static Route Example
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 192.168.0.100.
•
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 modem router, and a second static route was created to
your local network for all 192.168.0.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 192.168.0.100. The static route setup would look like
