8.7.1
LANs, WANs and the ZyXEL Device
The actual physical connection determines whether the ZyXEL Device ports are
LAN or WAN ports. There are two separate IP networks, one inside the LAN
network and the other outside the WAN network as shown next.

LAN and WAN IP Addresses
8.7.2 DHCP Setup
DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows
individual clients to obtain TCP/IP configuration at start-up from a server. You can
configure the ZyXEL Device as a DHCP server or disable it. When configured as a
server, the ZyXEL Device provides the TCP/IP configuration for the clients. If you
turn DHCP service off, you must have another DHCP server on your LAN, or else
the computer must be manually configured.
IP Pool Setup
The ZyXEL Device is pre-configured with a pool of IP addresses for the DHCP
clients (DHCP Pool). See the product specifications in the appendices. Do not
assign static IP addresses from the DHCP pool to your LAN computers.
8.7.3 DNS Server Addresses
DNS (Domain Name System) maps a domain name to its corresponding IP
address and vice versa. The DNS server is extremely important because without
it, you must know the IP address of a computer before you can access it. The DNS
server addresses you enter when you set up DHCP are passed to the client
machines along with the assigned IP address and subnet mask.
There are two ways that an ISP disseminates the DNS server addresses.
