Virtual Server
(Port Mapping)
Go to
Advanced Setup
Virtual Server
to set virtual server as you need. 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.
