DNS Source Interface Configuration

Use this page to specify the physical or logical interface to use as the DNS client source interface. When an IP
address is configured on the source interface, this address is used for all DNS communications between the
local DNS client and the remote DNS server. The IP address of the designated source interface is used in the
IP header of DNS management protocol packets. This allows security devices, such as firewalls, to identify all
source packets coming from a specific device.
To access the DNS Source Interface Configuration page, click System > Advanced Configuration > DNS >
Source Interface Configuration in the menu.
