4.5 NAT
This section contains configurations for the BR476n ’s advanced functions such as: virtual
server, and DMZ to provide your network under a security environment
4.5.1 DMZ
The DMZ feature allows one local user to be exposed to the Internet for special-purpose
applications like Internet gaming or videoconferencing. When enabled, this feature opens
all ports to a single station and hence renders that system exposed to intrusion from
outside. The port forwarding feature is more secure because it only opens the ports
required by that application.
