Virtual Server - Planet ADSL 2/2+ Router ADE-3400v2 User Manual

3.8.2 Virtual Server

Go to Advanced Setup ->NAT -> Virtual Server to set virtual server as you need.
(known as Port Mapping).
You can configure the router as a virtual server so that remote users accessing
services such as the Web or FTP at your local site via public 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 numbers), the router
redirects the external service request to the appropriate server (located at another
internal IP address). For some applications, you need to assign a set or a range of
ports (example 4000-5000) to a specified local machine to route the packets. The
router allows the user to configure the needed port mappings to suit such applications.
