access from the external networks. If you want to assign a global IP address to and use a printer/
multifunction machine, contact your network administr

Using Firewall to Restrict Transmission
A r
ewall is a system that prevents unauthorized access from the external networks and protects against attacks/
intrusions to a local area network. You can use a rewall on your network environment to block access from the
external network that appears to be dangerous, by restricting communication from specied IP address of the
external network. The function installed to a Canon printer/multifunction machine enables you to set up the IP
address lter. For information on how to set up an IP address lter, see
Specifying IP Addresses for Firewall
Settings(P
. 368) .
Specifying the TLS Encrypted Communication
For information on the TLS Encrypted Communication, see
Conguring the Network Security Settings

Setting PIN to Manage Information Stored in the Multifunction Machine
If a malicious thir
d party attempts to gain unauthorized access to a printer/multifunction machine, setting PIN to
information stored in the machine will reduce the risk of information leakage. Canon printers/multifunction machines
enable you to protect various type of information by setting PIN.
