      I upgraded to 2.2, removed squid and installed Squid3.

      None of my users can now browse http sites, and the firewall logs shows squid traffic being blocked:

      Direction=      OUT
      Source=        127.0.0.1:3128       
      Destination=  192.168.1.37:1068
      Protocol=      TCP:FA

      Any ideas?

        Out of state traffic. FA is a FIN ACK, FIN meaning "end", you know, French. The state has already been ended, but the other side doesn't seem to think so, so it sends a few more to make sure the other side knows this. Not exactly sure what situation causes this, but it seems to happen a lot.
