Placing a computer in the DMZ may

expose that computer to a variety of security

risks. This option is only recommended as a

last resort.

Firewall Settings

A ﬁrewall protects your network from the outside world. The router offers a ﬁrewall protection such as SPI (Stateful

Packet Inspection) and NAT/PAT (Network Address Translation/Port Address Translation). Sometimes you may want

a computer exposed to the outside world for certain types of applications. If you choose to expose a computer, you

can enable DMZ (Demilitarized Zone). This option will expose the chose computer completely to the outside world.
