ZyAIR B-4000 Hot Spot Gateway

Chapter 4

WAN, LAN and Server Setup

This chapter shows you how to configure LAN and WAN ports and server settings.

4.1Factory Ethernet Defaults

The Ethernet parameters of the ZyAIR are preset to the following values:

Dynamic WAN IP address.

LAN IP address of 192.168.1.1 with subnet mask of 255.255.255.0

DHCP server enabled on the LAN with a 253 client IP address pool starting from 192.168.1.2.

These parameters should work for the majority of installations. If you wish to change the factory defaults or to learn more about TCP/IP, please read on.

4.2LANs and WANs

A LAN (Local Area Network) is a computer network limited to the immediate area, usually the same building or floor of a building. A WAN (Wide Area Network), on the other hand, is an outside connection to another network or the Internet.

4.3IP Address Assignment

A static IP is a fixed IP that the ZyAIR obtains from a DHCP server on a network. A dynamic IP is not fixed; the DHCP server provides an IP address to the ZyAIR each time it connects to the network. When an Ethernet device is configured to obtain a dynamic IP address from a DHCP server, it is known as a DHCP client.

4.4DHCP Configuration

DHCP (Dynamic Host Configuration Protocol) allows the individual clients (Ethernet device) to obtain the TCP/IP configuration at start-up from a centralized DHCP server. The ZyAIR has built-in DHCP server capability, which means it can assign IP addresses, an IP default gateway and DNS servers to computer systems that support the DHCP client when this feature is activated. The ZyAIR can also act as a surrogate DHCP server where it relays IP address assignment from the actual DHCP server to the clients.
