[squid-users] How to make Squid 3.3.8 a transparent proxy?

Hi together,

I just upgraded Ubuntu 12.04 to 14.04 and with it I upgraded squid to
3.3.8. I am using a Dansguardian / Squid content filter on my localhost.
Dansguardian ist correctly working after the upgrade, but not Squid.

Here is my goal: configure Squid as a transparent proxy listening on
port 3128.

Here is me current squid.conf:
-----%<-----
acl SSL_ports port 443
acl Safe_ports port 80 # http
acl Safe_ports port 21 # ftp
acl Safe_ports port 443 # https
acl Safe_ports port 70 # gopher
acl Safe_ports port 210 # wais
acl Safe_ports port 1025-65535 # unregistered ports
acl Safe_ports port 280 # http-mgmt
acl Safe_ports port 488 # gss-http
acl Safe_ports port 591 # filemaker
acl Safe_ports port 777 # multiling http
acl CONNECT method CONNECT
http_access deny !Safe_ports
http_access deny CONNECT !SSL_ports
http_access allow localhost manager
http_access deny manager
http_access allow localhost
http_access deny all
http_port 3128 transparent
coredump_dir /var/spool/squid3
refresh_pattern ^ftp: 1440 20% 10080
refresh_pattern ^gopher: 1440 0% 1440
refresh_pattern -i (/cgi-bin/|\?) 0 0% 0
refresh_pattern (Release|Packages(.gz)*)$ 0 20% 2880
refresh_pattern . 0 20% 4320
-----%<-----

With the config above, squid starts correctly. But when I want to access
a website, squid says: "Access denied".

I tried hours all solutions I found in Google, but none worked. Can you
please help me?

Greetings,

Tobias
