Checking the Block Log
When IP addresses have been set so that data transmission and reception with the machine is denied, and data transmission and reception is attempted between the machine and the devices having those IP addresses, a block log is recorded. The procedure for referring to the block log is described below.
The procedure for setting IP addresses that are to be allowed/denied data transmission/reception with the machine is described in steps 12 and 13 of "TCP/IPv4 Settings," and steps 9 and 10 of "TCP/IPv6 Settings."
