WAN Screens
This chapter describes how to configure WAN settings.
5.1 WAN Overview
See Chapter 3 on page 51 for more information on the fields in the WAN screens.
5.1.1 TCP/IP Priority (Metric)
The metric represents the "cost of transmission". A router determines the best route for
transmission by choosing a path with the lowest "cost". RIP routing uses hop count as the
measurement of cost, with a minimum of "1" for directly connected networks. The number
must be between "1" and "15"; a number greater than "15" means the link is down. The
smaller the number, the lower the "cost".
The metric sets the priority for the ZyWALL's routes to the Internet. Each route must have a
unique metric.
5.1.2 WAN MAC Address
Every Ethernet device has a unique MAC (Media Access Control) address. The MAC address
is assigned at the factory and consists of six pairs of hexadecimal characters, for example,
00:A0:C5:00:00:02.
5.2 WAN Route Setup
Click WAN to open the Route screen.
