my limited knowledge suggests that this IS an ACL issue.
check in /var/log/messages as well as var/cache.log and var/error.log
(these are in the squid directory
and contains lots of useful debug messages) for more clues
are you sure you're not running a webserver on the reverse proxy machine
on port 80?
