5.1.1 What You Can Do in this Chapter
•Use the Broadband screen to view, remove or add a WAN interface. You can also configure the
WAN settings on the ZyXEL Device for Internet access (Section 5.2 on page 70).
•Use the 3G Backup screen to configure 3G WAN connection (Section 5.3 on page 81).
5.1.2 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 Device, which makes it accessible from an outside
network. It is used by the Device to communicate with other devices in other networks. It can be
static (fixed) or dynamically assigned by the ISP each time the Device 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).
3G
3G (Third Generation) is a digital, packet-switched wireless technology. Bandwidth usage is
optimized as multiple users share the same channel and bandwidth is only allocated to users when
they send data. It allows fast transfer of voice and non-voice data and provides broadband Internet
access to mobile devices.
IPv6 Introduction
IPv6 (Internet Protocol version 6), is designed to enhance IP address size and features. The
increase in IPv6 address size to 128 bits (from the 32-bit IPv4 address) allows up to 3.4 x 10
38
IP
addresses. The Device can use IPv4/IPv6 dual stack to connect to IPv4 and IPv6 networks, and
supports IPv6 rapid deployment (6RD).
