Using the restricted server list function
The Restricted Server List lets a system support person restrict which hosts are allowed to
communicate with the MFP over the network which prevents other hosts from managing and printing
to the MFP.
Note: The Restricted Server List only restricts TCP traffic; it does not affect UDP traffic.
The Restricted Server List supports up to ten host addresses or ten network
addresses.
To configure the Restricted Server List from the EWS of the MFP:
1 Open a Web browser.
2 In the address line, enter the IP address of the MFP requiring configuration using the format:
http://ip_address/.
3 Click Configuration.
4 Under Other Settings, click Network/Ports.
5 Click TCP/IP.
6 Enter the list of addresses in the Restricted Server List field for network communications
permission separated by commas in the following format: 111.222.333.444. To indicate an
entire subnet, provide the subnet mask bits in the format: 111.222.333.0/24.
