3.9.2 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.
3.9.3 DMZ Setting
Go to Advanced Setup ->NAT -> DMZ to set DMZ parameters.
If you have a local client PC that cannot run an Internet application properly from
behind the NAT firewall, you can open the client up to unrestricted two-way Internet
access by defining a virtual DMZ Host.
