Hi All, My configuration is Ubuntu-iptables-squid2.6/Transparent Proxy. I block gmail to all employees in my company. My problem is, squid does not block https://gmail.com. And does not even log https://gmail.com ! I didn't knew this until I've seen one of our employe browsing gmail! I did add this to my iptables : #iptables -t nat -A PREROUTING -i eth1 -p tcp --dport 443 -j DNAT --to eth0:3128 but get this meesage in access.log : error:unsupported-request-method Can anyone please help me how to block gmail. I want to block gmail/gtalk to all IPs except couple of IPs. Thanks Sohan Krishi
