4.3.2.7 Configuration—DNS
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 ADSL
Router records the available DNS servers and forwards DNS query messages to one of DNS servers.
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. DNS Proxy is enabled by default.
Auto Discovered: 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 Discovery + 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.
URL Name (Add/Delete): This is the URL name for the DNS server. This can be up to 255
characters.
Host IP (Add Only): This is the IP address of the DNS Server.
DNS Proxy Setting: This is a table of all DNS server IP addresses.
DNS Server Setting: This is a table of all DNS sever URL names.
Save Configuration: Clicking this will link the user to the Save Settings / Reboot page.
