DNS Servers Assigned by DHCP Server
The Prestige passes a DNS (Domain Name System) server IP address (in the order you specify here)
to the DHCP clients. The Prestige only passes this information to the LAN DHCP clients when you
select the DHCP Server check box. When you clear the DHCP Server check box, DHCP service is
disabled and you must have another DHCP sever on your LAN, or else the computers must have their
DNS server addresses manually configured.

7.3 Static DHCP Screen

This table allows you to assign IP addresses on the LAN to specific individual computers
based on their MAC addresses.

DESCRIPTION
DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132)
allows individual clients (computers) to obtain TCP/IP configuration at startup
from a server. Leave the Enable DHCP Server check box selected unless
your ISP instructs you to do otherwise. Clear it to disable the Prestige acting
as a DHCP server. When configured as a server, the Prestige provides TCP/IP
configuration for the clients. If not, DHCP service is disabled and you must
have another DHCP server on your LAN, or else the computers must be
manually configured. When set as a server, fill in the following four fields.
This field specifies the first of the contiguous addresses in the IP address pool.
This field specifies the size, or count of the IP address pool.
Select From ISP if your ISP dynamically assigns DNS server information (and
the Prestige's WAN IP address). The field to the right displays the (read-only)
DNS server IP address that the ISP assigns.
Select User-Defined if you have the IP address of a DNS server. Enter the
DNS server's IP address in the field to the right. If you chose User-Defined,
but leave the IP address set to 0.0.0.0, User-Defined changes to None after
you click Apply. If you set a second choice to User-Defined, and enter the
same IP address, the second User-Defined changes to None after you click
Apply.
Select DNS Relay to have the Prestige act as a DNS proxy. The Prestige's
LAN IP address displays in the field to the right (read-only). The Prestige tells
the DHCP clients on the LAN that the Prestige itself is the DNS server. When a
computer on the LAN sends a DNS query to the Prestige, the Prestige
forwards the query to the Prestige's system DNS server (configured in the
SYSTEM General screen) and relays the response back to the computer. You
can only select DNS Relay for one of the three servers; if you select DNS
Relay for a second or third DNS server, that choice changes to None after you
click Apply.
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 computer in order
to access it.
Click Apply to save your changes back to the Prestige.
Click Reset to begin configuring this screen afresh.
