NAT
NAT (Network Address Translation) is the translation between private IP and public IP.
NAT provides a way to allow multiple private hosts to access the public network using one
public IP at the same time, which alleviates the shortage of IP addresses. Furthermore, NAT
strengthens the LAN (Local Area Network) security since the address of LAN host never
appears on the internet. The router supports following NAT features:
■ One-to-One NAT
One-to-One NAT creates a relationship between a private IP address and a public IP
address. A device with a private IP address can be accessed through the corresponding
valid public IP address.
■ Virtual Servers
When you build up a server in the local network and want to share it on the internet, Virtual
Servers can realize the service and provide it to the internet users. At the same time
Virtual Servers can keep the local network safe as other services are still invisible from the
internet.
■ Port Triggering
Port Triggering is a feature used to dynamically forward traffic on a certain port to a
specific server on the local network. When a host in the local network initiates a connection
to the triggering port, all the external ports will be opened for subsequent connections. The
router can record the IP address of the host, when the data from the internet returns to the
external ports, the router can forward them to the corresponding host. Port Triggering is
mainly applied to online games, VoIPs, video players and so on.
