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. In addition, a block log for IP addresses and port numbers is recorded when transmitting data.
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 13 to 16 of "TCP/IPv4 Settings," and steps 9 to 11 of "TCP/IPv6 Settings."
