WLAN ADSL2+ Router
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.
