Accessible IP List
The NPort 6000 uses an IP address-based filtering method to control access to its serial ports.
The Accessible IP list allows you restrict network access to the NPort 6000. Access is controlled
by IP address. When the accessible IP list is enabled, a host’s IP address must be listed in order to
have access to the NPort 6000. You may add a specific address or range of addresses by using a
combination of IP address and netmask, as follows:
To allow access to a specific IP address
Enter the IP address in the corresponding field; 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
Deselect the Enable the accessible IP list option.
