That's a heck of a reason to switch OS's!

Run a sniffer like Ethereal and see what's happening.  Likely though, you
have something like proxy ARP set on the PIX and it's answering for any
address.

My Powerbook's been behind properly configured PIXen and worked just fine-
so I'd suspect the PIX config.
