Table 14 describes the fields in Figure 19.
Table 14 LAN IP
Label Description
DHCP Server With DHCP (Dynamic Host Configuration Protocol, RFC
2131 and RFC 2132) individual clients (workstations) can
obtain TCP/IP configuration at startup from a server. Unless
you are instructed by your ISP, leave this field set to
Server. When configured as a server, the Business Secure
Router provides TCP/IP configuration for the clients. When
set as a server, fill in the IP Pool Starting Address and
Pool Size fields.
Select Relay to have the Business Secure Router forward
DHCP requests to another DHCP server. When set to
Relay, fill in the DHCP Server Address field.
Select None to stop the Business Secure Router from
acting as a DHCP server. When you select None, you must
have another DHCP server on your LAN, or else the
computers must be manually configured.
IP Pool Starting Address This field specifies the first of the contiguous addresses in
the IP address pool. The default is 192.168.1.2.
Pool Size This field specifies the size, or count, of the IP address pool.
The default is 126.
DNS Servers Assigned by
DHCP Server
The Business Secure Router passes a DNS (Domain Name
System) server IP address (in the order you specify here) to
the DHCP clients. The Business Secure Router 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.
