NPort 5600 Series User’s Manual Web Console Configuration
Accessible IP Settings
NPort has an IP address based filtering method to control access to itself.
Accessible IP Settings allows you to add or block remote host IP addresses to prevent
unauthorized access. Access to NPort 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 to access the NPort. You can allow one of
the following cases by setting the parameter.
z Only one host with a specific IP address can access the NPort
Enter “IP address/255.255.255.255” (e.g., “192.168.1.1/255.255.255.255”).
z Hosts on a specific subnet can access the NPort
Enter “IP address/255.255.255.0” (e.g., “192.168.1.0/255.255.255.0”).
z Any host can access the NPort
Disable this function. Refer to the following table for more details about the configuration
example.
