Classification of Industrial VPN Routers

Common classifications of industrial VPN routers include 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. Allows remote users to securely access the corporate network by dialing into the ISP, directly connecting to the Internet or other networks.

L2TP is an industry-standard VPN network transmission tunneling protocol. Its functions are roughly similar to 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 packet header compression and tunnel authentication, while PPTP does not.

The IPSEC security protocol provides active protection and prevents 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. The security service of IPSec requires the support of shared keys to complete authentication and confidentiality, and requires manual key input.

What is the use of VPN for 4G industrial routers?

People who often come into contact with the communication industry are definitely not unfamiliar with VPNs. VPN is actually a virtual private network, which is to establish a private network on a public network for encrypted communication. The 4G dual-port industrial router developed and produced by NIUBOL fully considers the user's data security and is equipped with a powerful VPN function.

In fact, a virtual network is not a private network, but a virtual network can establish its own dedicated network channel on the public network, and realize the encryption of the communication process by using data communication network technology.

The VPN virtual network can facilitate the user's needs to the greatest extent. Through the use of long-distance data lines, it can build a network that best meets the needs for itself. Therefore, the use of VPN virtual private network can effectively speed up the user's network access speed.

A VPN is a temporarily established safe and dedicated virtual network. Users can use it with peace of mind at the network level. They only need to pay a certain amount of Internet access fees and avoid a series of unnecessary extra expenses. Users do not need to lease a dedicated line, which effectively saves a lot of operating costs and can save a lot of long-distance phone charges. And this is also the benefit of VPN.

Nowadays, with the development of online shopping, the e-commerce industry is taking off, and business applications at the network level have attracted more and more attention. The rapid development of online business applications relies on the strong support of VPN private networks. Various enterprises conduct business cooperation and exchanges through the network, which greatly improves the operation efficiency of the company.

The role of VPN in this link is that enterprises begin to allow their business partners and suppliers to access their own local area networks. In this way, the channels for information exchange are wider and the speed of information exchange is improved. The communication data between the VPN server and the client device can be processed in an encrypted state, reducing the risk of data leakage for enterprises.

Industrial VPN router application

At present, industrial routers are mainly used in the Internet of Things industries, such as electric power, water conservancy, transportation, finance, agriculture, forestry, coal mines, petrochemicals, environmental monitoring and protection, meteorology, fire protection, public safety, smart home, automation and other fields.
