DNS Setup
Use the DNS Setup menu to congure standard DNS server IP settings or to congure 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 Preferred 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 specic 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 difcult to locate a
specic host on the LAN using the standard DNS. For example, if you are running
a public web server 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, rst 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.
