The DIR-808L oers a rewall which helps protect your network from external threats. The SPI feature helps prevent malicious
attacks by inspecting and verifying incoming data packets. In certain cases, you may also want a computer exposed to the
outside world for certain types of applications. The rewall setup also features a Demilitarized Zone (DMZ) option, which will
expose the selected clients completely to the outside world.
