3.4.3 NAT
3.4.3.1 Overview
The DSL Router is equipped with the NAT function. With address mapping,
several users in the local network can access the Internet via one or more public
IP addresses.
You can activate or deactivate the NAT function when you select these
connection types of network protocol, for example, PPPoA, MER and IPoA. Once
you add a WAN interface with PPPoE, the NAT function is activated by default.
Otherwise, if selecting the type of Bridging, you could not configure NAT function.
3.4.3.2 Virtual Server Setup
The Virtual Server page is used to define applications that require special
handling by DSL router. All you need to do is to select the application protocol
and the local IP address of the computer that is using or providing the service.
You can also add new protocols, besides the most common ones provided by
DSL router.
Adding Virtual Servers
Step 1 To set up virtual servers for a service, choose Advanced Setup > NAT
> Virtual Servers Setup, and click Add.
