You cannot use the firewall configuration and still have Squid fetch
directly. You should be using a recent version of Squid (1.1.8 or
later) and try:

    cache_host foo parent 8080 7 no-query default

If your parent goes down, one user would get a "connection failed"
message, then all other requests will go direct. When Squid finds
that it can again make TCP connections to the parent, it will
stop going direct.
