Autre danger : les proxy transparents En principe, vous indiquez volontairement que vous voulez utiliser un proxy. Certains fournisseurs d'accès (comme Wanadoo ou AOL , dans certains cas), regardent quels protocoles vous utilisez et détournent sans vous le dire les requêtes HTTP vers leurs serveurs proxy.

Some ISPs use Transparent DNS Proxy technology to intercept DNS lookup requests (TCP/UDP port 53) and transparently proxy to their DNS servers. This forces your computer or router to use their DNS service for all DNS lookups instead of the ones you’ve set up. In this case Smart DNS technology wouldn’t normally work but we have a solution for this. Transparent DNS proxies. Some ISP's are now using a technology called 'Transparent DNS proxy'. Using this technology, they will intercept all DNS lookup requests (TCP/UDP port 53) and transparently proxy the results. This effectively forces you to use their DNS service for all DNS lookups. A transparent DNS proxy is the practice of intercepting DNS requests destined for a specific recursive DNS server (like DNSFilter), and sending the DNS requests to a completely different DNS server. This can be accomplished via: Firewall (Direct NAT)Network Security Appliance (Security Feature)S Proxy could fake my phone DNS (which is unchangeable in settings), so that it uses ISP DNS and not phone DNS. Most free transparent proxies intercept 53 port, however they are slow and unreliable. 8.8.8.8 as a DNS can't do it. – ripazha Sep 4 '13 at 6:13

Proxy DNS transparent. Certains FAI utilisent la technologie « DNS proxy transparent ». Il leur permet d’intercepter toutes les requêtes de recherche DNS (port TCP/UDP 53) et d’utiliser les résultats de manière transparente. C’est quelque chose qui vous oblige littéralement à utiliser leurs adresses DNS et il n’y a aucun moyen de

A multiplier les proxy en chaîne, on amplifie ce problème et on court aussi le risque de recevoir des documents falsifiés. En effet, s'il est intéressant de monter un proxy en tête d'un réseau local, il faut savoir que les FAI peuvent en utiliser aussi, de façon plus ou moins transparente (nous verrons ça plus loin). Un serveur proxy Je suis entrain de tester pfsense, et j'aurai aimé créer un proxy transparent à part (sur une autre machine que pfsense, car il n'est pas conseiller d'utiliser SQUID sur pfsense si il y a beaucoup de postes clients). voila mon architecture de test: FREEBOX (GW 192.168.1.254) | | WAN IP 192.168.1.1 PFSENSE | LAN IP 10.0.0.200 | –----- | | PC1 Proxy Squid 10.0.0.1 10.0.0.100. Comment je Note: Transparent proxies often don’t support DNS or DNSSEC. Specific transparent proxy software called Squid is able to manage HTTPS traffic in various ways. If a transparent proxy server has its HTTPS certificate authority set up by the network administrator, then the proxy server will perform as the middle man and HTTPS traffic will be decrypted at the proxy server, not at the destination Non-Transparent Proxy. The main reason to use a non-transparent proxy is so that the web browser and other client applications know that a proxy is being used, and so can act accordingly. Initial configuration of a non-transparent proxy might be trickier, but ultimately provides a much more powerful and flexible proxying service. Spyware and worms that use the web for transmission may not be

Les connexions effectuées par des navigateurs client via la passerelle sont déroutées vers le proxy sans qu'aucune configuration côté c
