A router uses a firewall to refuse unauthorized traffic entering the local area network, but administrators can set up a demilitarized zone, or DMZ, and instruct the networking device to send the traffic to a single computer on the network, effectively putting it “outside” of the firewall. This can be a workaround for some problems, but also means that the computer in the DMZ is more susceptible to attack. To put the computer back behind your firewall and keep your machines secure, disable the DMZ setting on the router.
