• Use the WAN Service screens to view, remove or add a WAN interface. You can also configure
the WAN settings on the VDSL Router for Internet access ( Section 4.4 on page 83 ).
• Use the 3G Backup screen to configure 3G WAN connection ( Section 4.5 on page 97 ).
4.1.2 What You Need to Know
The following terms and concepts may help as you read this chapter.
Encapsulation Method
Encapsulation is used to include data from an upper layer protocol into a lower layer protocol. To set
up a WAN connection to the Internet, you need to use the same encapsulation method used by your
ISP (Internet Service Provider). If your ISP offers a dial-up Internet connection using PPPoE (PPP
over Ethernet), they should also provide a username and password (and service name) for user
authentication.
WAN IP Address
The WAN IP address is an IP address for the VDSL Router, which makes it accessible from an
outside network. It is used by the VDSL Router to communicate with other devices in other
networks. It can be static (fixed) or dynamically assigned by the ISP each time the VDSL Router
tries to access the Internet.
If your ISP assigns you a static WAN IP address, they should also assign you the subnet mask and
DNS server IP address(es).
ATM
Asynchronous Transfer Mode (ATM) is a WAN networking technology that provides high-speed data
transfer. ATM uses fixed-size packets of information called cells. With ATM, a high QoS (Quality of
