5.4.2 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 the DHCP server 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.

5.4.3 DNS Server Address

There are two ways that an ISP disseminates the DNS server addresses.
• The ISP tells you the DNS server addresses, usually in the form of an information sheet,
when you sign up. If your ISP gives you the DNS server addresses, enter them in the DNS
Server fields in the LAN Setup screen.
• The ZyXEL Device acts as a DNS proxy when the Primary and Secondary DNS Server
fields are left blank in the LAN Setup screen.

5.4.4 LAN TCP/IP

The ZyXEL Device has built-in DHCP server capability that assigns IP addresses and DNS
servers to systems that support DHCP client capability.
