Hello, I have a LAN connect to internet through a Firewall Iptable with squid ( port 3128 for any protocols ) On my internet browser (workstation), I obtain this En essayant de charger l'URL : ftp://ftp.kernel.org/pub/ L'erreur suivante a été rencontrée : ? La connexion a échoué Le système a retourné : (13) Permission denied In my access.log, I have this message: 237 192.168.0.59 TCP_MISS/503 1564 GET ftp://ftp.kernel.org/pub/ - NONE/- text/html I have the same message when I try to connect to ssl connection. In my firewall's log I can not see any significant DROP. What the raison of a TCP_MISS/503 ? David,
