L’intégration des réseaux privés virtuels (VPN) dans les entreprises et les environnements informatiques est essentielle pour maintenir un accès sécurisé et à distance aux ressources de l’entreprise. Les entreprises adoptant de plus en plus des politiques de travail à distance et des services basés sur le cloud, la capacité à établir rapidement et en toute sécurité des connexions VPN devient cruciale. Dans cette optique, les scripts d’automatisation de la configuration du VPN jouent un rôle essentiel.
Contexte
Ce script PowerShell est conçu pour automatiser le processus de configuration d’une connexion VPN dans les environnements Windows. Il s’adresse aux professionnels de l’informatique et aux fournisseurs de services gérés (MSP) qui configurent régulièrement des VPN sur de nombreux appareils. Ce script permet non seulement de gagner du temps, mais aussi d’assurer la cohérence et de réduire la probabilité d’erreurs manuelles dans les configurations de VPN.

.SYNOPSIS
Creates a VPN using the built-in Windows VPN client, with configuration options from Ninja Documentation or Device Custom Fields.
.DESCRIPTION
This script will create a VPN using the built-in Windows VPN client. It will not create PPTP or "No Encryption" VPNs.
It can pull all the necessary VPN information from a Ninja Document or custom field you specify.
You can override the Documentation fields with parameters or only use parameters if you would like.
For more information on Ninja Documentation: https://ninjarmm.zendesk.com/hc/en-us/articles/360061218431-Documentation

Description détaillée
Ce script permet de créer une connexion VPN à l’aide du client VPN intégré de Windows. Il prend en charge différents types de VPN (comme L2TP, SSTP, IKEV2) et méthodes d’authentification. Le script peut récupérer les détails de la configuration VPN à partir d’un document NinjaOne ou de champs personnalisés, ce qui offre une grande flexibilité de déploiement.
Fonctions principales :
- Configuration de VPN: Il configure le VPN avec des options pour le type de tunnel, les méthodes d’authentification, les niveaux de chiffrement, et bien plus.
- Champs personnalisés et documentation: Il permet d’extraire des informations de VPN via la documentation NinjaOne ou de champs personnalisés spécifiques à l’appareil.
- Gestion des icônes: Le script peut télécharger une image pour l’icône du raccourci du VPN et même la convertir au format requis.
- Création de raccourcis: Il permet de créer un raccourci sur le bureau pour faciliter l’accès au VPN.
- Modification du registre: Pour certains VPN, il modifie le registre Windows pour activer l’encapsulation UDP.
- Option de remplacement: Il peut remplacer une connexion VPN existante portant le même nom.
Cas d’utilisation potentiels
L’administrateur informatique d’une entreprise de taille moyenne doit déployer une connexion VPN sécurisée pour tous les employés travaillant à distance. Grâce à ce script, ils peuvent rapidement établir une configuration VPN optimale sur tous les appareils, garantissant ainsi un accès sécurisé au réseau de l’entreprise.
Comparaisons
Traditionnellement, les VPN sont configurés manuellement via l’interface Windows ou à l’aide de scripts individuels. Ce script offre une approche plus unifiée et automatisée, réduisant le temps et les erreurs potentielles par rapport à une configuration manuelle.
