[System] > [Security] > [Host Access Restrictions]
Access control can be performed individually by address to access over the network. Set for IPv4 and IPv6, respectively.
Important
• To prohibit access via a proxy server in HTTP connection, a proxy server address must be set.
• Note that incorrect host restriction settings may prohibit access to the Settings Page itself, and there may be no way to recover other
