all protocols. Appendix C provides a table of commonly used protocol numbers and protocol
names.
Common services: Provides the common service ports using UDP or TCP. Among them, the
option "All" means all ports: Ports 1-65535.
After a port number (service) is selected, the system will automatically fill the port number in
"Destination starting port" and "Destination ending port". Specifically, if you select "All",
then fill in "destination starting port" and "destination ending port" as 1 and 65535
respectively.
Appendix D provides a table of common service ports and service names.
Destination starting port, destination-ending port: the destination starting port and destination
ending port for the access control policy, through which you can specify the destination ports
within a segment. If only one destination port is defined, then set them to the same value,
with the range of values as 1-65535.
Destination starting address, destination-ending address: The destination starting IP address
and destination ending address for the access control policy, through which you can specify
the destination IP addresses within a segment. If only one destination IP address is defined,
then they are set to the same value.
Source starting port, source-ending port: the source starting port and source ending port for
the access control policy, through which you can specify the source ports within a segment. If
only one source port is defined, then set them to the same value. Value range is 1-65535.
Effective time setting: The time when the access control policy takes effect. All times are not
to be set.
Tip:
The IP address field being 0.0.0.0 to 0.0.0.0 by default means that it takes effect to all clients, that
is, there is no limitation to the source address, including the clients in the LAN address field, the
clients of the PPPoE Server address pool.
