recommended that you set the IP address to * (star), because this
allows any Internet IP address to access the Broadband Router,
which could result in a loss of security for your network. If you elect
to enable Remote Management, enter the IP Address of your remote
location.
Port: The port number used to access the Broadband Router. (Select from
the pull-down menu.)
Example:
http://x.x.x.x:8080 where x.x.x.x is the WAN IP address of
the Broadband Router and 8080 is the port used for the
Web-Management interface.

Time
The system time is the time used by the DI-604 for scheduling services.
You can manually set the time or connect to a NTP (Network Time
Protocol) server. If an NTP server is set, you will only need to set the time
zone. If you manually set the time, you may also set Daylight Saving dates
and the system time will automatically adjust on those dates.
