Please show us your IPFW rules.

Maybe show us your squid.conf as well (without comments or blank lines).

Not in the sense that "you can't do this with only one interface", no.
However, quite possibly in the sense that you haven't told IPFW how to
distinguish between requests in from your clients, and requests out from your
squid instance.
The former need to go to squid, the latter need to go to the Internet.
Give us a bit more information and we might be able to give you a bit more
help.
