Abstract
The article is devoted to the study of such technology as IPsec VPN. The role of this technology in the field of information and communication technologies is quite significant. Firstly, IPsec VPN supports many modern encryption algorithms and authentication methods. Secondly, IPsec VPN is supported by many vendors, which allows you to deploy this technology based on equipment from different manufacturers. Thirdly, IPsec VPN does not require much performance from the hardware. Fourth, IPsec VPN is easy to use and easy to monitor. This article shows an example of IPsec VPN implementation on eNSP software environment based on Huawei equipment. As can be seen from the practical part of the article, the creation and implementation of this technology consists of only four steps.
