This refers to the network protection that is set in order to allow access to a secure network and block unsecure ones.
Hence, we can see that when a log-only rule is set and the source address is 112.101.2.4, a log would be created when a rule is set to allow all packets from 112.101.2.1 through 112.101.2.22.
