DHCP 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.

Client IP Pool Starting

Address

This field specifies the first of the contiguous addresses in the IP

address pool.

Size of Client IP Pool This field specifies the size or count of the IP address pool.

DHCP Server

Address

Type the IP address of the DHCP server in dotted decimal

notation (like 192.168.1.5).

First DNS Server

Second DNS Server

Third DNS Server

Select Obtained From ISP if your ISP dynamically assigns DNS

server information (and the Business Secure Router WAN IP

address). The field to the right displays the (read-only) DNS

server IP address that the ISP assigns.

Select UserDefined if you have the IP address of a DNS server.

Enter the DNS server IP address in the field to the right.

Select DNS Relay to have the Business Secure Router act as a

DNS proxy. The Business Secure Router LAN IP address

displays in the field to the right (read-only). The Business Secure

Router tells the DHCP clients on the LAN that the Business

Secure Router itself is the DNS server. When a computer on the

LAN sends a DNS query to the Business Secure Router, the

Business Secure Router forwards the query to the Business

Secure Router 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;

Select None if you do not want to configure DNS servers. If you

do not configure a DNS server, you must know the IP addresses

of devices or web sites in order to access them.

Back Click Back to go back to the previous screen.

Finish Click Finish to save the settings and proceed to the next wizard

screen.
