7.4 DMZ
If the DMZ Host Function is enabled, it means that you set up DMZ host at a particular
computer to be exposed to the Internet so that some applications/software, especially Internet /
online game can have two-way connections. A device acting as DMZ is not protected by the P-
330W's firewall.
To enable DMZ, click ADVANCED then the DMZ link. The screen appears as shown.

7.5 Virtual Servers (Port Forwarding)
The Virtual Server function is a list of inside (behind NAT on the LAN) servers, for example,
web or FTP, that you can make visible to the outside world even though NAT makes your
whole inside network appear as a single computer to the outside world.
You may enter a single port number or a range of port numbers to be forwarded, and the local
IP address of the desired server. The port number identifies a service; for example, web service
is on port 80 and FTP on port 21. In some cases, such as for unknown services or where one
server can support more than one service (for example both FTP and web service), it might be
better to specify a range of port numbers. You can allocate a server IP address that corresponds
to a port or a range of ports.
Many residential broadband ISP accounts do not allow you to run any server processes (such
as a Web or FTP server) from your location. Your ISP may periodically check for servers and
may suspend your account if it discovers any active services at your location. If you are
unsure, refer to your ISP.
