A Brief Analysis of Dynamic Multi-Point VPN using IPSec tunnel for secure data transmission over the Internet is the main solution for communication between Headquarters and branches of the company. Its commercial value will not be mentioned here, and it will take a long time to find a document. The IPSec network topology can be a star structure (hub-and-spoke) or a mesh structure (full mesh ). In practical

Unlike the previous rules, other intranet-based packets do not match this rule (such as OpenVPN connections) when accessing the public network through other interfaces.Although many connections are routed through different interfaces, it is not possible to assume that all links are like this.
