LABEL DESCRIPTION
DHCP Setup
DHCP Select what type of DHCP services the ZyXEL Device provides to the network.
Choices are:
None - the ZyXEL Device does not provide any DHCP services. There is
already a DHCP server on the network.
Relay - the ZyXEL Device routes DHCP requests to the DHCP server. There
may be a DHCP server on another network.
Server - the ZyXEL Device assigns IP addresses and provides subnet mask,
gateway, and DNS server information to the network. The ZyXEL Device is the
DHCP server for the network.

Server
The ZyXEL Device passes a DNS (Domain Name System) server IP address to
the DHCP clients.
Primary DNS Server

Server
This field is not available when you set DHCP to Relay.
Enter the IP addresses of the DNS servers. The DNS servers are passed to the
DHCP clients along with the IP address and the subnet mask.
If the fields are left as 0.0.0.0, the ZyXEL Device acts as a DNS proxy and
forwards the DHCP client’s DNS query to the real DNS server learned through
IPCP and relays the response back to the computer.
