Remote access to industrial routers is achieved through a VPN

In the era of Industrial Internet of Things (IIoT), remote access to industrial routers has become a key technology for enhancing operation and maintenance efficiency and reducing costs. Through VPN technology, users can securely connect to industrial routers to achieve functions such as device monitoring, configuration management, and data transmission. This article introduces to you how to remotely access an industrial router using a VPN, with a focus on the application of the ComFi I3000 Internet of Things industrial router.

Why is it necessary to use a VPN for remote access to industrial routers?

Industrial routers are typically deployed in complex environments such as factories, mines, and vehicles, resulting in high on-site maintenance costs and low efficiency. Through VPN technology, users can remotely access the router from anywhere with a network connection, achieving the following functions:

Equipment monitoring and management: Real-time viewing of equipment status, remote configuration and troubleshooting.
Data secure transmission: Data is transmitted through encrypted channels to prevent data leakage and tampering.
Reduce operation and maintenance costs: Decrease the frequency of on-site maintenance and enhance operation and maintenance efficiency.

How to remotely access an industrial router via a VPN?

Select the appropriate VPN protocol
Industrial routers support multiple VPN protocols, such as PPTP, L2TP, IPSec and OpenVPN. When choosing a protocol, compatibility and security should be taken into consideration. For instance, IPSec and OpenVPN protocols have relatively high security and are suitable for scenarios with high requirements for data security.
Configure the router’s VPN client
Take ComFi I3000 as an example. The steps to configure the VPN client are as follows:
Log in to the router management interface: Access the IP address of the router (such as 192.168.1.1) through a browser, and log in by entering the username and password.
Configure VPN parameters: Fill in the server address, port number, username and password, etc. in the “VPN Settings”. If the IPSec protocol is used, a pre-shared key also needs to be configured.
Set network parameters: To avoid IP conflicts, the local area network IP address of the router needs to be changed to be different from the IP segment of the VPN server.
Enable VPN connection: After saving the configuration, the router will automatically connect to the VPN server, and users can access the router through the VPN client.
Test the connection
After a successful connection, users can verify it through the following methods:
Ping industrial equipment using a local area network IP address in the control room or at a remote terminal.
Access the Web management interface of the router through the VPN client to configure and manage the device.
