Source Interface Configuration
Use the DNS Source Interface Configuration 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.
IP Address The IPv4 or IPv6 address associated with the configured Host Name.
For Static entries, specify the IP Address after you click Add. You can
specify either an IPv4 or an IPv6 address.
Total Time The number of seconds that the entry will remain in the table. The
function is only available for Dynamic entries.
Elapsed Time The number of seconds that have passed since the entry was added
to the table. When the Elapsed Time reaches the Total Time, the entry
times out and is removed from the table. The function is only available
for Dynamic entries.
Dynamic Type The type of address in the entry, for example IP or (less common)
X.121. The function is only available for Dynamic entries.
