Example: List of some well-known and registered port numbers.
The Internet Assigned Numbers Authority (IANA) is the central coordinator for the assignment of unique
parameter values for Internet protocols. Port numbers range from 0 to 65535, but only ports numbers 0 to
1023 are reserved for privileged services and are designated as “well-known ports” (Please refer to Table
5). The registered ports are numbered from 1024 through 49151. The remaining ports, referred to as
dynamic or private ports, are numbered from 49152 through 65535.
For further information, please see IANA’s website at:
For help on determining which private port numbers are used by common applications on this list, please

Time Schedule
The Time Schedule supports up to 16 time slots which helps you to manage your Internet connection.
In
each time profile, you may schedule specific day(s) i.e. Monday through Sunday to restrict or allowing the
usage of the Internet by users or applications.
This Time Schedule correlates closely with router’s time, since router does not have a real time clock on
board; it uses the Simple Network Time Protocol (SNTP) to get the current time from an SNTP server
from the Internet. Refer to
Time Zone
for details. You router time should correspond with your local time.
If the time is not set correctly, your Time Schedule will not function properly.
