Yes.

  * Look at the order of iptables rules for NAT rules which do things to
the packet before your interception rule.

  * Look at your network cabling layout, and routing configurations. To
see if packets actually flow through the Squid machine when the client
tries to connect directly to the Internet.

  * check that your Squid machine is configured as a network router
properly. In order to pass the packets through it this is required.
Neither "bridge" nor standalone proxy server is not enough for NAT
interception.

One or all of these could be the problem. You need to find out why and
we cannot help you much.

One "(squid)" is the worker which processes all the HTTP traffic. The
other "/usr/sbin/squid3" is the master control process which ensures
there is a worker always available, even if it crashes for some reason.
