Hi, everybody. I've just installed squid through apt-get in a debian squeeze server. The server has two NIC's. eth0 is connected to the LAN and eth1 has a public IP address. I've tried squid's default configuration and, after creating an acl and a rule to allow my computer to connect to squid
Code:
acl myMachine src myIp
Code:
http_access allow myMachine
I can perfectly browse the web. But I want to use squid as a TRANSPARENT PROXy, so I change the http_port option
Code:
http_port 3128 transparent
Then I add the following rule in my firewall
Code:
iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 80 -j REDIRECT --to-port 3128
Finally, I've configured the browser to first autodetect connection and later to use no connection at all and set the the LAN ip of the proxy server as default gateway of myMachine.
But I can't connect to internet.
