Internet Access 3-1
Chapter 3
Internet Access
This chapter shows you how to configure the LAN and WAN of your ZyAIR for Internet access.
3.1 Factory Ethernet Defaults
The Ethernet parameters of the ZyAIR are preset in the factory with the following values:
1. Ethernet IP address of 192.168.1.1 with subnet mask of 255.255.255.0 (24 bits).
2. DHCP server enabled with 32 client IP addresses starting from 192.168.1.33.
These parameters should work for the majority of installations. If the parameters are satisfactory, you can
skip to TCP/IP Ethernet Setup and DHCP to enter the DNS server address(es) if your ISP gives you explicit
DNS server address(es). If you wish to change the factory defaults or to learn more about TCP/IP, please
read on.
3.2 LANs 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.
3.2.1 LANs, WANs and the ZyAIR

separate IP networks, one inside, the LAN network; the other outside: the WAN network as shown next:
