This chapter describes how to configure WAN settings.

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

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.

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.

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.
