Filtering
It is possible to block packets, which trying to bring different source IP out from same
network. If packet brings different IP address, not its source IP address, then it is impos-

as max hosts for each port. In this case, you need to consider not only the number of PCs
in network but also devices such as switches in network.
For the hiD 6615 S223/S323, you have to lock the port like MAC filtering before configur-
ing max hosts. In case of ISPs, it is possible to arrange billing plan for each user by using
this configuration.
To configure max host, use the following command.
