Industrial VPN router

　　Industrial routers are industrial versions added on the basis of ordinary routers, and industrial VPN routers are VPN functions added on the basis of industrial routers. VPN generally refers to a virtual private network, which is simply a private network established on a public network for encrypted communication. The VPN function is to implement target address translation while encrypting data packets, and to perform remote access. Therefore, industrial VPN routers are very suitable for projects that require high data transmission security.

Why do industrial routers need to set up the VPN function? What are the benefits of the VPN function?

1. The VPN function allows people to be in complex public networks without worrying about security issues. Of course, this is also the basic function of industrial VPN routers;

　　2. It can solve the problem of using multiple devices for networking at the same time and needing to use the VPN function at any time. No more cumbersome operations after logging in and connecting for each device, as long as you switch a network, you can choose to use or not apply the VPN function, to achieve the effect of instant use;

　　3. Multiple connected devices are connected to the Internet, some need to use the local network, and some use the VPN network, so that they can be used in a staggered manner;

　　4. Industrial VPN routers can use one account to connect to multiple terminals, and there is no need to worry about VPN accounts restricting the number of connected terminals;

　　5. Most of the industrial routers on the market already support the PPTP connection mode in the VPN, and the fool-like operation setting is no longer the patent of the masters.

　　The VPN function is very popular in industrial, commercial, and civilian use. It can make network transmission safer, more professional, and more free.

　　Classification of industrial VPN routers The common classifications of industrial VPN routers are PPTP, L2TP, and IPSEC. The most common one is the PPTP protocol. As mentioned earlier, most of the industrial routers on the market have the PPTP security protocol, that is, the point-to-point tunneling protocol. It allows remote users to access the corporate network securely by dialing into the ISP, directly connecting to the Internet or other networks. L2TP is an industry-standard VPN network transmission tunnel protocol. Its function is roughly similar to that of the PPTP protocol. For example, it can also encrypt network data streams.

　　The difference is that PPTP uses a single tunnel, and L2TP uses multiple tunnels; L2TP provides header compression and tunnel verification, but PPTP does not support it. The IPSEC security protocol provides active protection and prevention of attacks through end-to-end security, and is the long-term direction of secure networking. In communication, only the sender and receiver are the only computers that understand IPSEC protection.

　　IPSec security services require support for shared keys to complete authentication and confidentiality, and require manual key input. How to set industrial VPN routers Industrial VPN routers of different brands have different settings, because the setting methods and built-in web page settings are all made by manufacturers. But the function is the same, and the setting method is similar.
