3.3.9 Configuration - DNS
The DNS Configuration page allows the user to set the configuration of DNS proxy. The
Conexant firmware supports the DNS proxy function. 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 modem recorded the available DNS
servers, and forward DNS query messages to one of DNS server.
• Disable DNS Proxy: 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 preferred
DNS sever or alternate DNS server whichever is available as the DNS server. Then all
DNS query messages will be directly sent to the DNS servers.
• Auto Discovery: The DNS proxy will store the DNS server IP addresses obtained from
DHCP client or PPP into the table. And all DNS query messages will be sent to one of the
dynamically obtained DNS servers.
