Industrial router VPN classification

VPN function of the industrial router is the basic configuration of VPN by using the industrial router. VPN technology is one of the important technologies of the router. Many network devices or software support VPN function. In a word, the core of VPN is to use the public network to establish a virtual private network.

I. classification of industrial router VPN

The common VPN categories of industrial routers are PPTP, L2TP and IPSEC. The most common one is the PPTP protocol. Most industrial routers on the market have PPTP security protocol, namely point-to-point tunnel protocol. Enables remote users to safely access enterprise networks by dialing into an ISP, directly connecting to the Internet, or over other networks.

L2TP is a kind of industrial standard VPN network transmission tunnel protocol, the function is roughly similar to the PPTP protocol, such as the same network data stream encryption. The difference is that PPTP USES a single tunnel and L2TP USES multiple tunnels. L2TP provides header compression and tunnel validation, while PPTP does not.

IPSEC security protocol provides active protection and prevention of attacks through end-to-end security, which is the long-term direction of secure networking. In communications, only the sender and receiver are the only computers that understand IPSEC protection. IPSec security services require support for Shared key completion authentication and confidentiality and require manual key entry.

II. VPN function of the industrial router

1, VPN function can let people in a complex public network, also do not worry about security issues. Of course, this is also the basic function of industrial VPN routers;

2. It can solve the problem of networking with multiple devices at the same time and using VPN function at any time. No longer need every device to log in and connect the cumbersome operation, as long as the switch of a network can choose to use or not applicable VPN function, to achieve the effect of out-of-the-box;

3, more than one connected device networking, some need to use local network, some use VPN network, so you can stagger the use;

4. Industrial VPN router can connect multiple terminals with one account, so it is no longer necessary to worry that the VPN account will limit the number of connected terminals;

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

VPN function is very popular in the industry, commerce, civil use, it can make network transmission safer, more professional, and cheaper.

These are the things about industrial VPN routers. All kinds of industrial routers of E-Lins have VPN functions, which fully support the mainstream VPN technologies such as IPsec, L2TP, PPTP, OpenVPN, GRE, APN, VPDN, etc. The high-strength and multi-level data encryption method ensures more secure data transmission.
