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.

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.

Static Routing

Go to

Advance Setup -> Routing ->Add ROUTE

to setup static route features.

The static routing function determines the path that router follows over your network before

and after it passes through your router. You can use static routing to allow different IP domain

users to access the Internet through this device.

Dynamic Routing

Go to

Interface Setup -> Internet

to select Dynamic Route as you need.

The dynamic routing feature of the router can be used to allow the router to automatically

adjust to physical changes in the network's layout. The router uses the dynamic RIP protocol. It

determines the route that the network packets take based on the fewest number of hops

between the source and the destination. The RIP protocol regularly broadcasts routing

information to other routers on the network

.
