You can view the connection to the Internet by running the command ipconfig/all in cmd, the PPP dial-up connection obtains a public IP address, which does not require port ing ()

2. ADSL uses a vro for dial-up, and the host shares the Internet through the vro. In this case, the host obtains a private intranet IP address of the 192.168.x.x type. In this case, it is necessary to map the port on the vro and forward the port to the corresponding server;
