For.information.on.how.to.confirm.the.IP.address,.see.“Setting.IPv4.Address”.in.the.e-Manual.
NOTE
If.a.global.IP.address.is.assigned.to.a.printer/multifunction.machine,.you.can.create.a.network.environment.to.
reduce.the.risk.of.unauthorized.access.by.installing.security.software,.such.as.a.firewall.that.prevents.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.“Restricting.Communication.by.Using.
Firewalls”.in.the.e-Manual.
