Clock Settings
In most cases, clock settings should not be changed from the default values. If you
know that your requirements are different from the defaults, click and adjust the
clock settings in the window displayed.
The Clock Settings button appears only if you are configuring a T1 or E1 serial
connection.

list of existing dynamic DNS methods opens. This menu choice is available

To clear an associated dynamic DNS method from the interface, choose None
