To filter by IP address it is possible to define up to four ranges which can be can be denied or
allowed connection to the copier by  setting the “Filter Mode” to ‘ALLOW’ or ‘DENY’. For
example, after an IP address range has been configured and the filter mode has been set to
‘ALLOW’, any connection attempts made to the copier (including ICMP echo (PING) requests,
print jobs or Internet Browser connections) from clients whose IP address falls outside of the
specified range will be rejected.

To filter by MAC address, enter the MAC address into one of the ten locations; only these
MAC addresses will be permitted to connect to the Network Card.
