04/04/2018 · Still, this is better to use than PPTP. And, because it can be configured to use AES encryption, is arguably more trustworthy than L2TP/IPsec. OpenVPN seems to be the best option. If you have to use another protocol on Windows, SSTP is the ideal one to choose. If only L2TP/IPsec or PPTP are available, use L2TP/IPsec. Avoid PPTP if possible
pptp和l2tp都使用ppp協議對數據進行封裝，然後添加附加包頭用於數據在互聯網絡上的傳輸。pptp只能在兩端點間建立單一隧道。 l2tp支持在兩端點間使用多隧道，用戶可以針對不同的服務質量創建不同的隧道。l2tp可以提供隧道驗證，而pptp則不支持隧道驗證。但是當l2tp 或pptp與ipsec共同使用時，可以由 Étape 8 : Après tous les paramètres, cliquez avec le bouton droit sur la connexion PPTP / L2TP , choisissez Connecter / Déconnecter et entrez le nom d' utilisateur et le mot de passe pour connecter le serveur VPN. 3 protocoles sont mis à disposition par Synology : PPTP, OpenVPN et L2TP/IPSec. Nous allons voir la configuration de chaque protocole mais sachez qu’OpenVPN est le protocole recommandé pour les ordinateurs de bureau équipés avec Windows, Mac OS X et Linux. Il offre les meilleures performances.
