1. As you can see, you need to enter the mapping port 8002 just specified on the router for 17 160.2. Similarly, if you are on the machine of 17 160.3, you need to enter the corresponding port 8003. When finished, click Save Configuration.

2. Enter the IP address of the router's LAN port in the browser, fill in the router's management user name and password correctly in the pop-up box, and then enter the management page.

3. For example, if you build a website, you only need to fill in a mapping setting with an internal network address of 19 162 and a port of 80. That is to say, when accessing this external network IP 1, the router directly transfers the access to port 80 of162.
