onClick="enable_change(false)"> Enable DNS forwarder

> Register DHCP leases in DNS forwarder
If this option is set, then machines that specify their hostname when requesting a DHCP lease will be registered in the DNS forwarder, so that their name can be resolved. You should also set the domain in System: General setup to the proper value.

> Register DHCP static mappings in DNS forwarder
If this option is set, then DHCP static mappings will be registered in the DNS forwarder, so that their name can be resolved. You should also set the domain in System: General setup to the proper value.

Note:
If the DNS forwarder is enabled, the DHCP service (if enabled) will automatically serve the LAN IP address as a DNS server to DHCP clients so they will use the forwarder. The DNS forwarder will use the DNS servers entered in System: General setup or those obtained via DHCP or PPP on WAN if the "Allow DNS server list to be overridden by DHCP/PPP on WAN" is checked. If you don't use that option (or if you use a static IP address on WAN), you must manually specify at least one DNS server on the System: General setup page.

You may enter records that override the results from the forwarders below.
 
Host Domain IP Description
       
 

Below you can override an entire domain by specifying an authoritative dns server to be queried for that domain.
