Advanced Configuration
DNS Setup
Use the DNS Setup menu to configure standard DNS server IP settings or to configure and enable DDNS for the Router.
DNS Server
Choose to “Obtain DNS server address automatically” from the ISP or enter DNS IP
address information manually. The Preffered DNS Server address is required, the
Alternate DNS Server address is used for a back up DNS server.
DDNS
Dynamic DNS allows a dynamic public IP address to be associated with a static host
name in any of the many domains, allowing access to a specific host from various
locations on the Internet. With this function enabled, remote access to a host will be
allowed by clicking a URL hyperlink in the following form: dlinkddns.com Because many
ISPs assign public IP addresses using DHCP, it can be difficult to locate a specific host
on the LAN using the standard DNS. For example, if you are running a public web serve
or VPN server on your LAN, DDNS ensures that the host can be located from the
Internet if the public IP address changes. DDNS requires that an account be set up with
one of the supported DDNS servers.
To implement Dynamic DNS, first select the Enable Dynamic DNS option and choose
the Server Address from the list in the pull-down menu. Enter the Host Name of the
LAN to be accessed, and the Username and Password for the DDNS account. Click the
Apply Settings button to save changes made.
