DNS Configuration
The DNS Configuration page allows you to set the configuration of
the DNS proxy. For the DHCP requests from local PCs, the DHCP server
will set the LAN port IP as the default DNS server. Thus, all DNS query
messages will come into LAN port first. The DNS proxy on the HNP
Router records the available DNS servers and forwards DNS query
messages to one of DNS servers.

DNS Configuration page
DNS Proxy Enable/Disable:
When the DNS Proxy is Disabled, the LAN port does not
process the DNS query message. For the DHCP requests from local PCs, the DHCP
server will set the user-configured DNS server as the DNS server. Then all DNS query
messages will be directly sent to the DNS servers.
Auto Discovery:
When enabled (default), the DNS proxy will store the DNS server IP
addresses obtained from DHCP client or PPP into the table. All DNS query messages
will be sent to the dynamically obtained DNS server. Select this option when the
DNS Server address is unknown but provided (automatically) by the ISP.
User Configured:
When enabled, the DNS proxy will use the user-configured DNS
server. All DNS query messages will be sent to the DNS server. Enter the DNS IP in the
DNS Server field. Select this option when the DNS Server address assigned by the ISP
is known. User Configured is disabled by default.
Auto Dis User Configured:
Selecting both options will cause the DNS proxy’s
table to have all the IP addresses of dynamically obtained and user configured
DNS servers.
DNS Server:
This is the user defined DNS server URL name and IP. Default is Disabled.
