WAN Setup

5.1

Overview

This chapter describes how to configure WAN settings from the

WAN

screens. Use these

screens to configure your ZyXEL Device for Internet access.

A WAN (Wide Area Network) connection is an outside connection to another network or the

Internet. It connects your private networks (such as a LAN (Local Area Network) and other

networks, so that a computer in one location can communicate with computers in other

locations.

5.1.1

What You Can Do in the WAN Screens

•

Use the

Internet Access Setup

screen (

Section 5.2 on page 70

) to configure the WAN

settings on the ZyXEL Device for Internet access.

•

Use the

More Connections

screen (

Section 5.3 on page 75

) to set up additional Internet

access connections.

•

Use the

WAN Backup Setup

screen (

Section 5.4 on page 80

) to set up a backup gateway

that helps forward traffic to its destination when the default WAN connection is down.

What You Need to Know About WAN

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) or PPPoA, 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) (and a gateway IP address if you use the Ethernet or ENET

ENCAP encapsulation method).

Multicast

Traditionally, IP packets are transmitted in one of either two ways - Unicast (1 sender - 1

recipient) or Broadcast (1 sender - everybody on the network). Multicast delivers IP packets to

a group of hosts on the network - not everybody and not just one.

IGMP

IGMP (Internet Group Multicast Protocol) is a network-layer protocol used to establish

membership in a Multicast group - it is not used to carry user data. There are three versions of

IGMP. IGMP version 2 is an improvement over version 1, but IGMP version 1 is still in wide

use. IGMP version 3 supports source filtering, reporting or ignoring traffic from specific

source address to a particular host on the network.

5.1.3

Before You Begin

You need to know your Internet access settings such as encapsulation and WAN IP address.

Get this information from your ISP.
