D-Link DI-1750 Reference Manual page 291

To the command of domain dynamic,the router will register to the primary server autoly,but if the
interface shut down, the communication to primary server will fail,that is,it can't register successly. In
order that the register goes along after the interface shut up, the modual set a much bigger timeout
and retry,so the configuring of retry and timeout go into effect after 30 seconds when the router reboots.
On the side, If we bind a domain name with an interface,when the ip address of the interface changed
and makes the communication to the primary server fail,but after a while,it can restore, at this instance,
we can enhance the times of retry and the seconds of timeout so that it can update successfully.
