They get that information from your browser. Not from the Firewall.

Forget about that or Secure your Browser. Use Firefox with NoScript and Adblock ...

sincerely

172.16 does not sound like your private IP address, it sounds like your PIX is working exactly right. You set an IP address for your PIX that the "world" can see, one usually designated by your ISP. Then you configure your truly private IP range inside of the PIX. When you go to the site, the only IP address found is your PIX's public address. In that way, anyone who tried to attack your computer would be attacking the PIX interface, and (hopefully) not have access to your internal files/computers/data.
