Setting Up access from the external networks. If you want to assign a global IP address to and use a printer/ multifunction machine, contact your network administrator. Using Firewall to Restrict Transmission A firewall 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 firewall on your network environment to block access from the external network that appears to be dangerous, by restricting communication from specified IP address of the external network. The function installed to a Canon printer/multifunction machine enables you to set up the IP address filter. For information on how to set up an IP address filter, see Specifying IP Addresses in Firewall Settings(P. 214) . Specifying the TLS Encrypted Communication For information on the TLS Encrypted Communication, see Configuring the Network Security Settings(P. 211) , and on the procedures to specify, see Configuring the Key and Certificate for TLS(P. 224) .
