BritePort 8120
NAT Application
The “NAT Applications”
page, similar to Figure 4-28,
provides a table for you to set
up public services on your
network, such as Web servers,
FTP servers, e-mail servers,
and/or other specialized
Internet applications that use
Internet access to perform
functions such as
videoconferencing. To
activate this feature, you are
required to subscribe at least
one static (or fixed) IP address
from your DSL serivce
provider and must select Allow server hosting in the “Internet Security” page.
To configure, select your service from the drop-down box under the Applications
column. Based on your selection, the default Port Number will appear. You may also
manually enter or revise the Port Number if needed. Then, type the fixed Server IP
address for the hosting computer. Finally, click Apply to confirm your settings.
Activating your setup defined in the NAT Application table will trigger the port
forwarding function of your BritePort 8120. That is, once your BritePort 8120 receives
requests, via the DSL connection, for a specific NAT Application, your BritePort 8120
will automatically forward the requests to the appropriate hosting computer within your
LAN.
Your BritePort 8120 supports up to 9 NAT Applications plus 1 DMZ (demilitarized
zone) for port forwarding. The DMZ allows you to expose all ports of one LAN
computer to the Internet. This feature is especially important when you want to host
services such as the Internet gaming and videoconferencing -- allowing a large number
of users to access the service simultaneously.
