DGN1000 Setup Manual.
The default ADSL settings of your wireless modem router work fine for most ISPs. However,
some ISPs use a specific multiplexing method and virtual circuit number for the virtual path
identifier (VPI) and virtual channel identifier (VCI).
NAT (Network Address Translation) NAT automatically assigns private IP addresses (10.1.1.x) to
LAN-connected devices.
• Enable. Usually NAT is enabled.
• Disable. This disables NAT, but leaves the firewall active.
Disable NAT only if you are sure you do not need it. When
NAT is disabled, only standard routing is performed by this
router. Classical routing lets you directly manage the IP
addresses that the wireless modem router uses. Classical
routing should be selected only by experienced users

Router MAC Address The Ethernet MAC address used by the wireless modem
router on the Internet port. Some ISPs register the MAC
address of the network interface card in your computer when
your account is first opened. They will then accept traffic only
from the MAC address of that computer. This feature allows
your wireless modem router to use your computer’s MAC
address (this is also called cloning).
• Use Default Address. Use the default MAC address.
• Use Computer MAC Address. The wireless modem router
will capture and use the MAC address of the computer that
you are now using. You must be using the one computer that
is allowed by the ISP.
• Use This MAC Address. Enter the MAC address that you
want to use.
a. Disabling NAT reboots the wireless modem router and resets its configuration settings to the factory defaults. Disable NAT
only if you plan to install the wireless modem router in a setting where you will be manually administering the IP address space
on the LAN side of the router.
