Accessible IP Settings
The NPort 5100A 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 the NPort 5100A 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 5100A. You can allow one of the following cases by setting the
parameter.
• Only one host with a specific IP address can access the NPort 5100A
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 5100A
Enter “IP address/255.255.255.0” (e.g., “192.168.1.0/255.255.255.0”).
• Any host can access the NPort 5100A
Disable this function by un-checking the “Enable the accessible IP list” checkbox. Refer to the following
table for more configuration examples.
