Hello, Our customer has a transparent Zscaler proxy. The clients do Name resolution. They use a central DNS forwarder but have local Internet access with tunnels to Zscaler. The central DNS forwarder has it’s own central Internet Access. Do you have a solution for geolocation DNS (required by Microsoft) and transparent Zscaler proxy? Many thanks for your feedback Si vous utilisez un proxy transparent ou WPAD dans votre topologie réseau, vous n’avez pas besoin de paramètres de configuration spéciaux. Pour plus d’informations sur les exclusions d’URL Microsoft Defender ATP dans le proxy, voir autoriser l’accès aux URL du service Microsoft Defender ATP sur le serveur proxy. because if your ISP is really running a transparant proxy, your routers DNS requests will still get intercepted by your ISP. If you want to really block their DNS servers, block the offending DNS servers IPs and see if the network breaks. If it does not, you should no longer be using your ISPs DNS servers. THe risk is that if your ISP is doing this right, your connection will break because all C'est pourquoi, le proxy transparent apparait etre un bon compromis entre configuration et filtrage des applications. Celui ci agit sur le réseau comme s'il s'agissait d'un routeur (pas de configuration superflue de la part de l'utilisateur) , mais filtre comme un serveur proxy (bloque les applications autres que celles définies par l'administrateur). A transparent proxy on the other hand, also known as a forced or intercepting proxy, is a middle man system deployed by your ISP. It is referred to as ‘transparent’ because the client is unaware of its existence. A transparent proxy acts as an intermediary between you and a website you want to visit. While you are connecting to that website, the proxy intercepts the connection, before passing it to the website. This does put your data privacy and online behaviour in jeopardy. Read on Bonjour, Merci pour la mise à jour de votre article, j'avais un problème de dns il fallait que je forward mes dns !!!

Une solution plus transparente est d’utiliser un proxy. Le proxy HTTP, comme son nom l’indique, ne va s’interposer que pour les requêtes HTTP, c’est à dire votre navigateur et les autres logiciels qui utilisent ce protocole et qui supportent les proxies (Spotify, Nextcloud…). Unfortunately this means they now proxy all your DNS traffic using a transparent DNS proxy, regardless of what DNS resolver you have set on your client. I.e you may have Cloudflare’s 1.1.1.1 configured on your local device, DNS requests will still be answered by Sky. Transparent proxy has different names, and some of its most common names are inline proxy, intercepting proxy, and forced proxy. A Transparent proxy is used to analyze the users’ requests by intercepting it and performs different actions including, redirection, authentication and caching.

A transparent proxy is a device that operating on the network layer is able to redirect the traffic to a proxy server without any configuration on the client side.

Un proxy DNS intelligent vous permet de contourner cette restriction. Voici un diagramme expliquant comment cela fonctionne : Au lieu d'obtenir cette adresse de la part d'un serveur DNS local, un proxy DNS intelligent vous connectera à un serveur DNS qui semble être situé au bon emplacement géographique et vous donne accès au service.
