Bonjour Mips,

Depuis ce week-end, j’ai récupéré une connexion externe fonctionnelle à 100%, mais je ne sais pas pourquoi au final puisque je n’ai pas changé grand chose en lien avec ce problème. 
Je bascule de ma box 4G vers ma box ADSL généralement en fin de mois (forfait 4G épuisé) - Tout mon réseau LAN est géré par un système ORBI donc mes adresses IP ne sont pas impactées.Cependant mon adresse IP externe change forcément.
Est ce que cela pourrait générer des problèmes avec OpenVPN ? Sachant que j’effectue cette opération régulièrement depuis 1 an et que cela n’a jamais posé de problème dans le passé.
PS : Merci pour la note sur les droits, j’étais passé au travers.
