Access control can be performed individually by address to access over the network. Set IPv4 and IPv6, respectively.
Note
If the same address is entered, the setting that is displayed higher on the list will be applied.
IPv4 Host Access Restrictions
Specify the hosts from which IPv4 access is permitted and prohibited. This setting is common to wired and wireless LANs.
[Apply Host Access Restrictions]
Select whether to use IPv4 host access restrictions.
[Default Policy]
Select whether to allow or block access from IPv4 addresses that have not been specified in [Network Address/Subnet].
[Network Address/ S ubnet]
Enter IPv4 addresses into the list and select [Yes] or [No] for access for each address.
It is possible to specify the subnet to set access restrictions by network or host.
If set to [No], access to all ports is blocked.
IPv6 Host Access Restrictions
Specify the hosts from which IPv6 access is permitted and prohibited.
[Apply Host Access Restrictions]
Select whether to use IPv6 host access restrictions.
[Default Policy]
Select whether to allow or block access from IPv6 addresses that have not been specified in [Prefix/Prefix Length].
[Prefix/Prefix Length]
Enter IPv6 addresses (prefixes) into the list and select [Yes] or [No] for access for each address.
It is possible to specify the prefix length to set access restriction by network or host.

Important
• To prohibit access via a proxy server in HTTP connection, a proxy server address must be set.
• If host access restriction is set mistakenly, access to the Settings Pages themselves may be prohibited, in which case restoring the
factory default settings will become the only means of recovery.
