Some devices allow you to create VPNs. A Virtual Private Network (VPN) allows you to connect up to things behind a firewall. For this example, you need to ping from pc0 to a number of different things just to see how the VPN works. Make sure you edit one or more of the firewalls to see how the VPN is configured, and see how the static route is defined to make the packets go through the VPN. You will need to know how that works to solve the rest of this level. Certains appareils vous permettent de créer des VPN. Un réseau privé virtuel (VPN) vous permet de vous connecter à des choses derrière un pare-feu. Pour cet exemple, vous devez envoyer un ping de pc0 à un certain nombre de choses différentes pour voir comment fonctionne le VPN. Assurez-vous d'éditer un ou plusieurs pare-feu pour voir comment le VPN est configuré et voyez comment l'itinéraire statique est défini pour faire passer les paquets par le VPN. Vous aurez besoin de savoir comment cela fonctionne pour résoudre le reste de ce niveau.
