You also need "httpd_accel_uses_host_header on", as it says in the FAQ at, but that won't solve the problem you are
having. By default, squid listens on port 3128. The "httpd_accel_port
80" simply means that when squid sees a packet destined for port 80, it is
supposed to accept that packet. That does _not_ mean that squid is
listening on port 80. If a packet arrives on port 3128 and the packet was
headed for port 80 on some computer, squid will accept it. How does this
happen? Read the FAQ at


1. packets headed for port 80 on some computer on the Internet must be
   redirected by the router to the computer where squid is _running_
2. that computer must redirect the packets to port 3128 where squid
   is _listening_
