NPort 5200 uses 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 5200 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 5200. You can allow one of the following cases by setting the parameter.
 Only one host with a specific IP address can access the NPort 5200
Enter “IP address/255.255.255.255” (e.g.,
“192.168.1.1/255.255.255.255”).
 Hosts on a specific subnet can access the NPort 5200
Enter “IP address/255.255.255.0” (e.g., “192.168.1.0/255.255.255.0”).
 Any host can access the NPort 5200
Disable this function by un-checking the “Enable the accessible IP list”
checkbox. Refer to the following table for more configuration
examples.
