WAN Setup
This chapter describes how to configure WAN settings.
5.1 WAN Overview
A WAN (Wide Area Network) is an outside connection to another network or the Internet.
5.1.1 PPP Multilink
The ZyXEL Device uses the PPP Multilink Protocol (PPP/MP) to bundle multiple links in a
single connection to boost the effective throughput between two nodes.

Due to the fragmentation/reconstruction overhead associated with MP, you may not get a
linear increase in throughput when a link is added.

The number of links in an MP bundle can be statically configured, or dynamically determined
at runtime, as explained in the following section.

5.1.2 Bandwidth on Demand
The Bandwidth on Demand (BOD) feature adds or subtracts links dynamically according to
traffic demand. After the initial call, the ZyXEL Device uses BAP (Bandwidth Allocation
Protocol) to ask the peer for additional telephone number if BACP (Bandwidth Allocation
Control Protocol) is negotiated. Otherwise, the ZyXEL Device uses the statically configured
(primary and secondary) telephone numbers of the remote node.

5.1.3 IP Address Assignment
A static IP is a fixed IP that your ISP gives you. A dynamic IP is not fixed; the ISP assigns you
a different one each time. The Single User Account feature can be enabled or disabled if you
have either a dynamic or static IP.
