Security - IP Filter

This page allows you to configure the IP Filter setting for jobs to be received with the LPD and Port9100 protocols. Enter the IP addresses and address masks that you want the printer to control connections from and select [Reject], [Accept], or [Off]. The IP addresses and address masks must be in IPv4 format, a series of four numbers between 0 and 255. IPv6 addresses cannot be specified.

Setting Order of IP Addresses/Address Masks
You can set a maximum of five IP addresses/address masks, and the first pair will be given a priority. If setting multiple IP addresses/address masks, enter the pair that covers the smallest area first.


The following explains how to set [IP Filter].
