Overview

This chapter describes the Device’s

Broadband

screens. Use these screens to configure your

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.

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 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) (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 and 3 are improvements over version 1, but IGMP version 1 is still in wide use.

IPv6

IPv6 (Internet Protocol version 6), is designed to increase IP address space and enhance features.

The Device supports IPv4/IPv6 dual stack and can connect to IPv4 and IPv6 networks.
