VPN – What is VPN and how it works?
A VPN (virtual private network) offers network connection possibility over an extensive physical distance (remoteness). But you need to know that it can work over both on private networks and public networks (Internet).
VPN in simple words make possible for clients or whole LAN-s on other side of the internet to connect into main LAN pesmises and have the “technical impression” that they are localy connected to this site. This includes gaining the local IP address from local DHCP pool, possibility to use all the LAN resources that are defined by the administrator etc.
