This chapter describes how to configure LAN settings.
5.1  LAN, WAN and the ZyXEL Device
A network is a shared communication system to which many computers are attached. 
The Local Area Network (LAN) includes the computers and networking devices in your home 
or office that you connect to the ZyXEL Device’s LAN ports.  
The Wide Area Network (WAN) is another network (most likely the Internet) that you connect 
to the ZyXEL Device’s WAN port. See 
 for how to use the WAN screens 
to set up your WAN connection. 
The LAN and the WAN are two separate networks. The ZyXEL Device controls the traffic that 
goes between them. The following graphic gives an example.

5.2  IP Address and Subnet Mask
Similar to the way houses on a street share a common street name, so too do computers on a 
LAN share one common network number.
Where you obtain your network number depends on your particular situation. If the ISP or 
your network administrator assigns you a block of registered IP addresses, follow their 
instructions in selecting the IP addresses and the subnet mask.
If the ISP did not explicitly give you an IP network number, then most likely you have a single 
user account and the ISP will assign you a dynamic IP address when the connection is 
established. If this is the case, it is recommended that you select a network number from 
192.168.0.0 to 192.168.255.0 and you must enable the Network Address Translation (NAT)
