IP Address seen by Internet Users
Once configured, anyone on the Internet can connect to your Virtual Servers.
Please note that, in the above picture, both Internet users are connecting to the same IP address, but
using different protocols, such as Http://203.70.212.52 and Ftp://203.70.212.52.
To Internet users, all virtual servers on your LAN have the same IP Address. This IP Address is
allocated by your ISP. This address should be static, rather than dynamic, to make it easier for
Internet users to connect to your Servers. However, you can use Dynamic DNS feature to allow users
to connect to your virtual servers by using a URL, instead of an IP address.
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).
Add New Port Forwarding
To set a virtual server, please open the Virtual Server item from the Advanced setup menu.
To add a new Port Forwarding, please click Add from the Port Forwarding web page.
