the DHCP server you are going to use so the Relay Agent can help 
to forward the DHCP request to the DHCP server. 
DNS Server 
Configuration
 
DNS stands for Domain Name System. Every Internet host must 
have a unique IP address, also they may have a human-friendly, 
easy to remember name such as www.yahoo.com. The DNS server 
converts the user-friendly name into its equivalent IP address. 
 
Primary IP Address -You must specify a DNS server IP address 
here because your ISP should provide you with usually more than 
one DNS Server. If your ISP does not provide it, the router will 
automatically apply default DNS Server IP address: 194.109.6.66 
to this field. 
Secondary IP Address - You can specify secondary DNS server IP 
address here because your ISP often provides you more than one 
DNS Server. If your ISP does not provide it, the router will 
automatically apply default secondary DNS Server IP address: 
194.98.0.1 to this field.   
The default DNS Server IP address can be found via Online Status: 
 
If both the Primary IP and Secondary IP Address fields are left 
empty, the router will assign its own IP address to local users as a 
DNS proxy server and maintain a DNS cache.   
If the IP address of a domain name is already in the DNS cache, the 
router will resolve the domain name immediately. Otherwise, the 
router forwards the DNS query packet to the external DNS server 
by establishing a WAN (e.g. DSL/Cable) connection. 
There are two common scenarios of LAN settings that stated in Chapter 4. For the 
configuration examples, please refer to that chapter to get more information for your 
necessity.
