DNS. Tor does not support UDP so we cannot simply redirect DNS queries to the Tor transparent proxy. Most DNS leaks are avoided by having the system resolver query the Tor network using the DNSPort configured in torrc.. There is a concern that any application could attempt to do its own DNS resolution without using the system resolver; UDP datagrams are therefore blocked in order to prevent leaks. Transparent firewall means that the proxy uses the layer-7 proxy advantages without the knowledge of the client. The client presumes that the gateway is a NAT in layer 3, and it does not have any idea about the inside of the packet, but through this method, the layer-3 packets are sent to the layer-7 proxy for investigation.

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.
