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 specied 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

Setting PIN to Manage Information Stored in the Multifunction Machine
If a malicious thir
