  Not off hand, but that at least points in the right direction. You
now need to get the AIX box to accept TCP/IP packets "promiscuously",
i.e. for any TCP/IP address. (Note this is *not* quite the same as the
Ethernet promiscuous mode used in sniffers.)

  Check the ip filters package referenced in the FAQ and see if it
supports AIX or can be ported to it. Otherwise, you may have to look
at AIX docs to see how to do it in AIX, or if it even can be done
without changing kernel source. Your basic task is to get something
running that runs at the IP kernel level, accepts packets to any IP
address, port 80, on the desired interface, and routes them all to a
specified port number on the loopback interface. Squid should take it
from there.

  tcpdump will be your greatest friend in this.
