6.2. PORT MAPPING
Port mapping is mapping a port of outside web host’s IP address to a machine inside web, and provide the service. When
user connects to the port of the IP, the server will automatically map the request to the corresponding machine inside
LAN.
With the function of port mapping, we can map many ports of a machine’s IP address to different machines’ different ports
inside web. The port mapping can also have other special agent functions, like POP, SMTP, TELNET, etc.
Theoretically, it can provide more than sixty thousand ports.
For example, if we want to map a web server which has an IP address of 192.168.111.10, we just need to input the IP
address and TCP port 80 into the port mapping chart of the router.
There are two ways to map the port: UPnP function automatically map and modify the router’s port mapping chart by
manual.
