From Internet Host IP Address:
Select the initial place for port forwarding. If
you choose SINGLE, a box will appear for
you to fill in the IP address for the specific
host. And, if you choose SUBNET, the boxes
of IP and Subnet will appear for you to fill in
the IP address and subnet mask for the
specific host as the start point.
Forwarded to Internet Host IP Address:
Type in the address for the host used as the
place that information will be forwarded.
IP addresses can be automatically redirected to local servers configured with private IP addresses. In
other words, depending on the requested service (TCP/UDP port number), the router redirects the
external service request to the appropriate server (located at another internal IP address).
After adding a new virtual server, click
Apply .
The following screen will be shown to
display the status for new ones.
If you do not want the new server that you
added, please check the
Delete box of that
one and click the Delete button to discard it.
Or if you want to add another one again,
click
Add to add a new one.
Connecting to the Virtual Servers
Once configured, anyone on the Internet can connect to your Virtual Servers. They must use the
Internet IP Address (the IP Address allocated to you by your ISP.) For example,
Http://203.70.212.52
Ftp://203.70.212.52
It is more convenient if you are using a Fixed IP Address from your ISP, rather than Dynamic.
However, you can use the Dynamic DNS feature to allow users to connect to your Virtual Server
through a URL, rather than an IP Address.
Virtual Server-Port Triggering
When the router detects outbound traffic on
a specific port, it will set up the port
forwarding rules temporarily on the port
ranges that you specify to allow inbound
traffic. It is supposed to increase the support
for Internet gaming, video conferencing, and
Internet telephony due to the applications
require multiple connection.
To add a new port triggering, click Add to
open this web page. Than choose an
application name from the Pre-defined list
box. The system provides 9 items for your
choice.
