AC1600 WiFi VDSL/ADSL Modem Router Model D6400
Connection Mode Select how the Internet connection functions:
• Always On. Once the Internet connection is established, it remains on.
This is the default setting.
• Dial on Demand. When someone attempts to connect to the Internet,
the Internet connection is established. When the idle time-out period
expires, the Internet connection is terminated.
• Manually Connect. You must connect to the Internet manually (see
View, Renew, or Release a TCP/IP Internet Connection on page 230 or
View, Connect, or Disconnect a PPPoE or PPPoA Internet Connection
on page 232).
Idle Timeout (In Minutes) If you select Dial on Demand from the Connection Mode menu, enter the
idle time-out period in minutes.
The idle time-out specifies how long the modem router keeps the Internet
connection active when no one on the network is using the Internet
connection. The default is 5 minutes. To disable the idle time-out, enter 0.
(When you disable the idle time-out, the connection is not terminated

to the modem router during login, select this option and enter the IP
address of your ISP primary DNS server. If a secondary DNS server
address is available, enter it also.
NAT (Network Address Translation)
NAT allows computers on your home network to share the modem router Internet connection. NAT is
enabled by default because it is required in most situations. Select the NAT setting:
• Enable. NAT is enabled. This is the default setting. Leave this setting if no reason to disable NAT
• Disable. NAT is disabled.
Router MAC Address
The Ethernet MAC address that the modem router uses 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 accept
traffic only from the MAC address of that computer. This feature allows your modem router to use your
computer’s MAC address (also called cloning).
Use Default Address Use the default MAC address.
