The Virtual Server Page - Zoom Wireless-N User Manual

The Virtual Server Page

You can use the Virtual Server page to configure a virtual server.
Because your Router's NAT 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 on the router.
Server IP
This is the IP Address of the computer or gaming device that you want to allow
access to. If you do not know the IP address you can look it up by selecting Basic
Settings > LAN Setup, then clicking on Client List. To make this virtual server
permanent, then you should set up a fixed mapping to your computer or gaming
device on the LAN Setup page. Doing this ensures that your computer will keep the
same IP address.
Service Port
This is the port number you want to allow access to your computer on.
Private Port
Usually the private port should be set to the same port as the service port. However if
you want to hide the port you are using internally from the outside world you may set
a private port. Data will come in over the service port and the Router will switch the
port used by the data to the private port. Computers on your network will see the data
on the private port but users outside your firewall will see the data on the service port.
Protocol
Select UDP, TCP, or Both depending on what type of protocol your game or
application uses.
