Setting item | Description | |
|---|---|---|
[Filtering Method] | [No Filtering] | Disables IP filtering. |
[Sync. IP Address] | Allows accesses of only the IP addresses in the specified range in IPv4 environment. The subnet mask is fixed to 255.255.255.0. Allows accesses of only the IP address set to this system and the IP addresses of which the high-order 64 bits are the same in IPv6 environment. | |
[Sync. Subnet Mask] | Allows accesses of only the IP address set to this system and the IP addresses included in the same sub network. | |
[IPv4 Access Range] | If [Sync. IP Address] or [Sync. Subnet Mask] is set in [Filtering Method], the valid range of the IPv4 IP addresses is displayed. Security can be enhanced by restricting communications from an IP address outside the valid range. For details about how to acquire the IP address, refer to [IPv4 Settings]. | |
[IPv6 Access Range] | If [Sync. IP Address] or [Sync. Subnet Mask] is set in [Filtering Method], the valid range of the IPv6 IP addresses is displayed. Security can be enhanced by restricting communications from an IP address outside the valid range. For details about how to acquire the IP address, refer to [IPv6 Settings]. | |
