4.6 Configuring Static DHCP

The Static DHCP screen allows you to assign IP addresses on the LAN to specific individual
computers based on their MAC Addresses.
Every Ethernet device has a unique MAC (Media Access Control) address. The MAC address
is assigned at the factory and consists of six pairs of hexadecimal characters, for example,
00:A0:C5:00:00:02.
To change your Prestige's static DHCP settings, click LAN, then the Static DHCP tab. The
screen appears as shown.

DESCRIPTION
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.
Enter the IP address of your Prestige in dotted decimal notation, for example,
192.168.1.1 (factory default).
Type the subnet mask assigned to you by your ISP (if given).
IGMP (Internet Group Multicast Protocol) is a network-layer protocol used to
establish membership in a multicast group. The Prestige supports both IGMP
version 1 (IGMP-v1) and IGMP-v2. Select None to disable it.
Select the RIP direction from None, Both, In Only and Out Only.
Select the RIP version from RIP-1, RIP-2B and RIP-2M.
Click Apply to save your changes back to the Prestige.
Click Reset to begin configuring this screen afresh.
