DNS - Configuration

1.The DNS Configuration page allows users to set the configuration of DNS proxy.

There are four DNS proxy modes availabe:

1.Disable DNS Proxy: The LAN port does not process query message. For the DHCP requests from local PCs, the DHCP server will set the user-configured preferred DNS server or alternate DNS server whichever is availabe as the DNS server. Then all DNS query messages will be directly sent to the DNS servers.

2.Use Auto Discovered DNS Servers Only: 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 o the dynamically obtained DNS servers.

3.Use User Configured DNS Servers Only: The DNS proxy will use the user-configured preferred DNS server and alternate DNS server. And all DNS query message will be sent to one of DNS servers.

4.Auto Discovery + User Configured: The DNS proxy's table has all the IP addressess of dynamically obtained and user configured DNS servers.
