What is the difference between ‘network-to-network’ connection and ‘point-to-network’ connection?

‘Network-to-network’ connection allows accessing any computers that are in the local environment to any virtual machine. It is a great option for hybrid configurations. For this type of connection VPN device supporting IPSec is needed. To create ‘network-to-network’ connection you should have this VPN equipment and IPv4 public IP address. ‘Point-to-network’ connection permits you to access from any computer locating anywhere. For this type of connection VPN-client is used. This variant is very useful in case if there is no access to VPN hardware or IPv4 address, which are necessary for ‘network-to-network’ connection.
