Unidentified subject!

Below I've attached part of my squid.conf, I am currently using
squid-2.3.STABLE3 on a Freebsd 3.4-stable box. I'm currently using ipfilter
to divert traffic, and make a transparent proxy.

My current configuration unfortunate has the result of being an open proxy,
on the external interface as well. Is there there a way with squid to
prevent this? or do I need to set a ipfw rule?

Thanks
Sameer
