In the deployment of the Industrial Internet of Things (IIoT), 4G industrial router play a pivotal role, especially in areas where wired networks are difficult to cover or deploy at a high cost. In practical applications, there is often a need to map a service on the 4G industrial router to the public network for remote access and management. This involves the concept and operation of IP mapping. As a senior engineer in the field of industrial IoT, I will explain in detail how to perform IP mapping on a 4G industrial router.
Firstly, it is crucial to understand what IP mapping is. In simple terms, IP mapping involves assigning a public IP address and port to a specific internal IP address and port on the router, enabling external networks to access the service within the router. In the context of 4G industrial routers, this is typically done to facilitate remote access, data sharing, or device monitoring.
Next, let's explore the steps involved in performing IP mapping on a 4G industrial router. Generally, the process can be divided into the following steps:
Before performing IP mapping, it is essential to understand the current network environment, including the connection method of the 4G industrial router, the network topology, and the allocation of internal IP addresses. Additionally, it is necessary to clarify the specific mapping requirements, such as the IP address and port of the service to be mapped, as well as the external access methods and security requirements.
Access the management interface of the 4G industrial router through a web browser or dedicated configuration software. Typically, this requires entering the router's IP address and the corresponding username and password.
Within the router management interface, locate the NAT or port mapping configuration options. Depending on the brand and model of the router, the location and name of this option may vary. In the NAT configuration, you need to set the internal server's IP address and port number, as well as the public IP address and port number to be used for external access. This ensures that when external networks access the public IP address and port, the router automatically forwards the traffic to the internal server.
To ensure security, it is also necessary to configure firewall rules that allow external networks to access the internal service through the mapped port. Simultaneously, restrictions should be placed on unnecessary access and potential attacks.
After completing the configuration, testing is required to ensure the successful IP mapping. This can be done by accessing the mapped public IP address and port from an external network to check if the internal service is accessible.
It's worth noting that different brands and models of 4G industrial routers may have varying configurations for IP mapping. Therefore, it is advisable to refer to the router's official documentation or technical support for more specific configuration guidance during actual operations.
Furthermore, while IP mapping facilitates remote access and management of devices, it also poses certain security risks. Therefore, when configuring IP mapping, it is crucial to consider security issues and adopt necessary security measures such as using strong passwords, limiting access permissions, and regularly updating firmware.
IP mapping on a 4G industrial router is a relatively complex but crucial operation. Through reasonable configuration and management, we can achieve remote access and management of devices, enhancing the application effectiveness of the industrial IoT.
