Only hosts within the defined IP address range can communicate with the VSP One File management software and network devices.
- From the app switcher, select System Administrator.
- Navigate to Access > Security Options > Allowed Hosts.
- Set Restrict Access to Allowed Hosts toggle switch to on to add the Allowed Hosts to define individual IP addresses or a range of IP addresses that are allowed to access the VSP One File management software and devices on the network.
Optionally, you can enter the allowed hosts using the IP address/netmask format, that is a netmask is added immediately following the IP address, and is separated from the IP address by a slash (/). The netmask can use the standard #.#.#.# format. For example, 192.0.2.0/255.255.255.0.
Alternatively, you can enter the allowed hosts in network CIDR format (IP address/prefix), where the prefix is a simple number between 0 and 32. For example, 192.0.2.0/24.
The value of specifying a prefix with an IP address is that you can allow access by a range of IP addresses with a single entry. For example, to allow access only by hosts having an IP address in the range 192.0.2.0 through 192.0.2.255, you could add the single entry 192.0.2.0/24 instead of entering each of the 256 entries individually.Note: The netmask component does not directly specify the IP address at the end point of a range. For example, entering 192.0.2.0/192.0.2.255 does not allow VSP One File access for the hosts in the range 192.0.2.0 through 192.0.2.0. Instead, to allow VSP One File access by all hosts in the range 192.0.2.0 through 192.0.2.255, you would enter 192.0.2.1/255.255.255.0 or 192.0.2.0/24.The format for IPv6 address is: #:#:#:#:#:#:#:#, for example, fdca:f995:220a:480:1::a (which specifies a single host) or fdca:f995:220a:480:1::a/64 (which specifies a range of IP addresses in CIDR format).
