How to implement an intranet application without a public ip, multiple ports, fixed ports, or UDP on the Internet

When there is a public IP address, you can use Route ing to enable the Internet to ask intranet. However, when there is no public IP address, how does one implement the Internet ingress and ask intranet applications?

The hardware routing method can use the software port ing method because it is unavailable without the public network. For example, open full port ing for nat123.

The principle of full port ing is to bind the domain name to the server in the Intranet software, and the Internet is implemented through the domain name's asking questions. In this method, you do not need to change the Failover port, but you need to enable the point-to-point failover client at the same time during the Failover.

Implementation process:
1. The intranet uses the open nat123port ing.
2. Add the ing. Select full port ing.
3. The Internet address can use its own domain name or directly use the prompt second-level domain name.

4. After the ing is saved successfully, you do not need to set a route.
5. When an Internet region asks about an intranet application, enable the internal server on the internal server at the same time and add the internal server to the internal server, you can ask the internal server about all applications on the Intranet without changing the internal server port.
