Accessible IP Settings
NPort has an IP address based filtering method to control access to the NPort.
Accessible IP Settings allows you to add or remove “Legal” remote host IP addresses to prevent
unauthorized access. Access to NPorts is controlled by IP address. That is, if a host’s IP address is in
the accessible IP table, then the host will be allowed access to the NPort. You can allow one of the
following cases by setting the parameter.
Only one host of specific IP address can access the NPort
Enter “IP address/255.255.255.255” (e.g., “192.168.1.1/255.255.255.255”).
Hosts on the specific subnet can access the NPort
Enter “IP address/255.255.255.0” (e.g., “192.168.1.0/255.255.255.0”).
Any host can access the NPort
Disable this function. Refer to the following table for more details about the configuration
example.
