Controlling the access to this machine by IP address

IPv4 address filtering

The computers' access to this machine can be controlled via IP address. This is called "IP address filtering".

You can specify both IPv4 addresses that are allowed to access this machine and those refused to access the machine.

In the administrator mode, select [Network] - [TCP/IP Setting] - [IP Address Filtering], then configure the following settings.

Settings	Description
[IPv4 Filtering (Permit Access)]	Select [Enable] to specify IPv4 addresses that allow access. Also enter the range of IPv4 addresses that allow access. To allow access from a single IPv4 address, you can only enter the address in one side of the range. Example of entry: "192.168.1.1" [Disable] is specified by default.
[IPv4 Filtering (Deny Access)]	Select [Enable] to specify IPv4 addresses refused to access. Also enter the range of IPv4 addresses. To refuse access from a single IPv4 address, you can only enter the address in one side of the range. Example of entry: "192.168.1.1" [Disable] is specified by default.
