If the usage of a protocol or print application is not permitted on your device, it cannot be used even after
its IPv4 address is permitted on the machine; on your device, configure the settings to permit the protocol
or print application.
This machine logs attempts to gain access from IPv4 addresses that it has been set to reject. For
instructions on how to refer to the access log, see "Viewing the Network Access Log(p.8-32)."
