First DNS Server

Second DNS Server

Third DNS Server

Select From ISP if your ISP dynamically assigns DNS

server information (and the Business Secure Router'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.

Select DNS Relay to have the Business Secure Router act

as a DNS proxy. The Business Secure Router's 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's system

DNS server (configured in the SYSTEM General screen)

and relays the response 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

address of a machine in order to access it.

LAN TCP/IP

IP Address Type the IP address of your Business Secure Router in

dotted decimal notation (192.168.1.1 (factory default).

IP Subnet Mask The subnet mask specifies the network number portion of

an IP address. Your Business Secure Router 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 Business Secure Router

255.255.255.0.

RIP Direction With RIP (Routing Information Protocol, RFC 1058 and

RFC 1389) a router can exchange routing information with

other routers. The RIP Direction field controls the sending

and receiving of RIP packets. Select the RIP direction from

Both/In Only/Out Only/None. When set to Both or Out

Only, the Business Secure Router broadcasts its routing

table periodically. When set to Both or In Only, it

incorporates the RIP information that it receives; when set

to None, it does not send any RIP packets and ignores any

RIP packets received. None is the default.
