Note: If your ISP requires MAC authentication and another MAC address
has been previously registered with your ISP, then you need to enter
that address on the Broadband Advanced Options screen for the
WAN interface (see
Configure Advanced WAN Options and Other
Tasks on page 50).
Configure Dynamic DNS
Dynamic DNS (DDNS) is an Internet service that allows devices with varying public IPv4
addresses to be located using Internet domain names. To use DDNS, you need to set up an
account with a DDNS provider such as DynDNS.org, TZO.com, Oray.net, or 3322.org. (Links
to DynDNS, TZO, Oray, and 3322 are provided for your convenience as option arrows on the
DDNS configuration screens.) The wireless VPN firewall firmware includes software that
notifies DDNS servers of changes in the WAN IP address so that the services running on this
network can be accessed by others on the Internet.
If your network has 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 will not know
in advance what your IP address will be, and the address can change frequently—hence, the
need for a commercial DDNS service, which allows you to register an extension to its
domain, and restores DNS requests for the resulting fully qualified domain name (FQDN) to
your frequently changing IP address.
