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.
