automatically forward the traffic on the incoming port to the computer that accessed
the outgoing port. If your game uses one port to send outgoing data and a different port
(or ports) for incoming data, you may want to use port triggering. The advantage of
port triggering is that it is more secure than setting up a virtual server since the
incoming port is only open when you are using it, and since it tracks which computer
sent the outgoing data. Port triggering can also be easier to set up because you do not
need to know the IP address of your gaming station. The disadvantage of port
triggering is that only 1 host can be accessing the port at one time, so if you have two
computers or game stations playing the same game on your network you will need to
use a virtual server or DMZ.
A DMZ differs from a virtual server in that it allows access on all ports of the computer.
Because of this, DMZ's are less secure and should be used with caution on your
computer. However DMZ's work well with your gaming stations since security is not as
much of an issue for gaming stations as it is for computers.
Some games support UPnP. If your game supports UPnP then you do not need to set
any forwarding rule since UPnP will automatically set up the router to work with the
game.
You can use the Forwarding Rules page to configure the options mentioned above, for
allowing access to devices behind your router.
The Virtual Server Page
You can use the Virtual Server page to configure a virtual server.
Because your router's firewall filters out unrecognized packets to protect your network,
all computers behind this product are invisible to the outside world. If you want, you
can make some of them accessible by enabling Virtual Server mapping.
A virtual server will allow access to your computer on certain ports. A port is like a
channel that is used by applications (such as games) to communicate on. For
example, the directions for the game you want to play over the Internet might tell you
to open port 6000.
