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 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 device act as a DNS proxy. The device tells the DHCP
clients on the LAN that the device itself is the DNS server. When a computer on
the LAN sends a DNS query to the device, the device forwards the query to the
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.
DHCP Server IP If Relay is selected in the DHCP field above, then type the IP address of the
actual, remote DHCP server here.
Pool Size This field specifies the size, or count of the IP address pool.
First DNS Server IP
Second DNS
Server IP The device 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.
