Accessible IP Settings
The Accessible IP list allows you enable only certain IP addresses to connect to the NPort device
server and attached devices. When the accessible IP list is enabled, only IP addresses that are on
the list will be able to connect to the NPort. You can allow single IP addresses or a range of IP
addresses by using a combination of IP address and netmask, as follows:
 To allow access to a specific IP address
Enter the exact IP address and enter 255.255.255.255 for the netmask.
 To allow access to hosts on a specific subnet
For both the IP address and netmask, use 0 for the last digit (e.g., 192.168.1.0 and
255.255.255.0).
 To allow unrestricted access
Do not enable the accessible IP list.
The following table shows additional examples:
