DDNS
The Router offers a Dynamic Domain Name System (DDNS)
feature. DDNS lets you assign a fixed host and domain
name to a dynamic Internet IP address. It is useful when
you are hosting your own website, FTP server, or other
server behind the Router.
Before you can use this feature, you need to sign up for
DDNS service at one of two DDNS service providers,
DynDNS.org or TZO.com. If you do not want to use this
feature, keep the default, Disable.
DDNS Service
If your DDNS service is provided by DynDNS.org, then
select DynDNS.org from the drop-down menu. If your
DDNS service is provided by TZO, then select TZO.com.
The features available on the DDNS screen will vary,
depending on which DDNS service provider you use.

Setup > MAC Address Clone
Some ISPs will require you to register a MAC address
in order to access the Internet. A MAC address is a
12-digit code assigned to a unique piece of hardware for
identification. If you do not wish to re-register the MAC
address with your ISP, you can use the MAC Address Clone
feature to assign the currently registered MAC address to
the Router.
