LABEL DESCRIPTION
DHCP Mode DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows
individual clients (computers) to obtain TCP/IP configuration at startup from a
server.
Select None if you do not want to configure DNS servers. If you do not configure
a DNS server, you must know the IP address of a machine in order to access it.
When configured as a Server, the ZyXEL device provides TCP/IP configuration
for the clients. When set as a Server, fill in the rest of the DHCP setup fields.
Select Relay to have the ZyXEL device act as a DNS proxy. The ZyXEL device
tells the DHCP clients on the LAN that the ZyXEL device itself is the DNS server.
When a computer on the LAN sends a DNS query to the ZyXEL device, the
ZyXEL device forwards the query to the ZyXEL device’s system DNS server and
relays the response back to the computer. You can select Relay and enter an IP
Pool Starting Address. The First DNS Server IP and Second DNS Server IP will
appear as read only fields.
IP Pool Starting
Address This field specifies the first of the contiguous addresses in the IP address pool.
Pool Size This field specifies the size, or count of the IP address pool.
First DNS Server IP
Second DNS
Server IP The ZyWALL passes a DNS (Domain Name System) server IP address (in the
order you specify here) to the DHCP clients. Type your First DNS Server IP and
Second DNS Server IP addresses in these fields.
Remote DHCP
Server If Relay is selected in the DHCP field above, then type the IP address of the
actual, remote DHCP server here.
