DMZ (SPA122 Only)
Use the
Network Setup > Application > DMZ
page if you need to allow a local
device to be exposed to the Internet for a special-purpose service.
The specified network device must have its DHCP client function disabled and
must have a reserved IP address (also known as a static IP address) to ensure that
it is reachable at the specified IP address. To reserve an IP address for a device,
see
Network Settings for the LAN and DHCP Server (SPA122 Only), page 29
.
NOTE
A Demilitarized Zone (DMZ) is similar to Port Range Forwarding. Both features allow
Internet traffic to access a resource on your private network. However, Port Range
Forwarding is more secure because it only opens the ports that you specify for an
application. DMZ hosting opens all the ports of one device, exposing it to the
Internet.
