Set Access Restrictions
[Security] > [Host Access Restrictions]
Separate access control from IPv4 and IPv6 addresses can be set.
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 Setting Pages themselves may be prohibited, in which case restoring the
factory default settings will become the only means for recovery.
Note
If the same address is duplicated, the policy for the address that appears highest on the list will be applied.

IPv4 Host Access Restrictions

[Apply Host Access Restrictions]
Select whether to use IPv4 host access restrictions.
[Default Policy]

[Network Address / Subnet]
Enter IPv4 addresses into the list and select [Yes] or [No] for access for each address.
You can specify the subnet to set access restrictions by network or host.
If set to [No], access to all ports is blocked.
