Chapter 5 LAN Setup 78

Table 13 LAN IP

LABEL DESCRIPTION

DHCP

DHCP Server Enable the DHCP server to have the Prestige assign IP addresses, an IP default

gateway and DNS servers to Windows 95, Windows NT and other systems that

support the DHCP client.

When DHCP is used, the following items need to be set:

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.

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.

First DNS Server

Second DNS Server

Third DNS Server

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.

TCP/IP

IP Address Enter the IP address of your Prestige in dotted decimal notation, for example,

192.168.1.1 (factory default).

IP Subnet Mask The subnet mask specifies the network number portion of an IP address. Your

Prestige automatically calculates the subnet mask based on the IP address that

you assign. Unless you are implementing subnetting, use the subnet mask

computed by the Prestige.

Multicast 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.

RIP Direction Select the RIP direction from None, Both, In Only and Out Only.

RIP Version Select the RIP version from RIP-1, RIP-2B and RIP-2M.

Multicast 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.
