6.8 Removing the Restriction Caused by the Binding of
the Internet Access Account to the MAC Address
Function Overview
Certain network service providers bind your Internet access account to the MAC address
of your computer's network adapter; only the computer with that MAC address can
connect to the Internet. When this is the case, the MAC address of the router cannot be
found in the network devices of a network service provider. As a result, the router cannot
connect to the Internet and the computers connected to the router also cannot access the
Internet.
You can use the MAC address cloning function of the router to remove this restriction.
Through this function, the MAC address used during communication between the router
and the network devices of a network service provider becomes the MAC address that is
bound to the Internet access account. The router can then be connected to the Internet
properly.
Configuration Example
If you use computer 1 to access the Internet, your network service provider binds your
Internet access account to the MAC address of computer 1's network adapter. Now, if
multiple computers are added to your home and you need to use the router to access the
Internet, you can use the MAC address cloning function of the router to change the MAC
address of the router to that of computer 1's network adapter.

6.9 Allowing Internet Users to Access an Internal
Resource Server
Function Overview
Without special settings, Internet users cannot access the web or FTP servers on a LAN.
By using the network address translation (NAT) function of the router, specified Internet
users are allowed to access the web and FTP servers on a LAN.
Furthermore, IP addresses used by most users to access the Internet are dynamically
assigned by network service providers, so many cannot use fixed IP addresses to access
the resources provided on servers. The router's Dynamic Domain Name Service (DDNS)
function allows Internet users to use fixed domain names to access the resources
provided on servers.
After the DDNS function is enabled, the router automatically submits the new IP address
obtained to the server of a DDNS provider. On the DDNS server, the IP address that
corresponds to the domain name is updated to the latest IP address. When a computer on
the Internet accesses the domain name, the DDNS server provides the latest IP address to
that computer.
Configuration Example
If you deploy a web server on a LAN and want Internet users to be able to access the web
site on the web server through a fixed domain name, the IP addresses of relevant devices
should be as follows:
The IP address of the router LAN interface is 192.168.3.1.
