Restricting Access from Specific IP Addresses

You can register the IP address to restrict or allow the access to the machine.
Use the Remote UI to specify IP addresses. You can only select to enable or disable this feature using the operation panel.

Restart the machine to activate these settings.
NOTE
Setting IPv4 address:
[Single Address]
Specify a single address to be denied or allowed at a time.
[Multiple Addresses]
Specify a range of addresses to be denied or allowed.
This setting is useful when you want to specify a series of addresses, such as 192.168.0.1 to 192.168.0.20, at a time.
You can specify up to 4 addresses (4 ranges of addresses), including both [Single Address] and [Multiple Addresses].
You cannot specify the address that consists of all zeros.
Setting IPv6 address:
[Single Address]
Specify a single address to be denied or allowed at a time.
[Multiple Addresses]
Specify a range of addresses to be denied or allowed.
This setting is useful when you want to specify a series of addresses, such as fe80::10 to fe80::20, at a time.
[Prefix Address]
Specify a prefix of which to be denied or allowed.
This setting is useful when you want to specify addresses of the same prefix.
You can specify up to 4 addresses (4 ranges of addresses), including all [Single Address], [Multiple Addresses], and [Prefix Address].
You cannot specify the multicast address (address that starts with "ff") or the address that consists of all zeros.
