Operation Manual

DNS
The DNS Configuration page allows you to set the configuration of DNS proxy.
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.
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 of the dynamically
obtained DNS servers.
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.
Auto Discovery + User Configured:
The DNS proxy’s table has all the IP addresses of dynamically obtained and user
configured DNS servers.
User Configuration:
Place your primary and secondary DNS addresses here.
