You can attach a 3G wireless adapter to the USB port and set the ZyXEL Device to
use this 3G connection as your WAN or a backup when the wired WAN connection
fails.

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 98
).
Use the
3G Backup
screen to configure 3G WAN connection (
Section 5.3 on
page 112
).

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 ZyXEL Device, which makes it
accessible from an outside network. It is used by the ZyXEL Device to
communicate with other devices in other networks. It can be static (fixed) or
dynamically assigned by the ISP each time the ZyXEL 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).
ATM
Asynchronous Transfer Mode (ATM) is a LAN and 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 Service) can be guaranteed. ATM
uses a connection-oriented model and establishes a virtual circuit (VC) between
two endpoints before the actual data exchange begins.
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.
Finding Out More
See
Section 5.4 on page 114
for advanced technical information on WAN and
3G.
See
Chapter 3 on page 37
for WAN tutorials.

Before You Begin
You need to know your Internet access settings such as encapsulation and WAN IP
address. Get this information from your ISP.

The Broadband Screen
The ZyXEL Device must have a WAN interface to allow users to use the Ethernet
WAN port or DSL port to access the Internet. Use the
Broadband
screen to view,
remove or add a WAN interface.
Note: The ATM and Ethernet layer-2 interfaces cannot work at the same time.
Click
Network Setting > Broadband
. The following screen opens.

This is the index number of the connection.
Name
This is the service name of the connection.
Type
This shows the type of interface used by this connection.
Mode
This shows whether the connection is in routing mode or bridge mode.
Encapsulation
This shows the method of encapsulation used by this connection.
VPI
This is the Virtual Path Identifier (VPI).
VCI
This is the Virtual Channel Identifier (VCI).
Vlan8021p
This indicates the 802.1P priority level assigned to traffic sent through
this connection. This displays
N/A
when there is no priority level
assigned.
VlanMuxId
This indicates the VLAN ID number assigned to traffic sent through
this connection. This displays
N/A
when there is no VLAN ID number
assigned.

Add/Edit Internet Connection
Use this screen to configure a WAN connection. The screen varies depending on
the encapsulation and WAN service type you select.
IGMP Proxy
This shows whether IGMP (Internet Group Multicast Protocol) is
activated or not for this connection. IGMP is not available when the
connection uses the bridging service.
NAT
This shows whether NAT is activated or not for this connection. NAT is
not available when the connection uses the bridging service.
Default Gateway
This shows whether the ZyXEL Device uses the interface of this
connection as the system default gateway.
Modify
Click the
Edit
icon to configure the connection.
Click the
Delete
icon to delete this connection from the ZyXEL Device.
A window displays asking you to confirm that you want to delete the
connection.
