Weird stuff, I do not understand the Web Preview thing.
The G web preview sends an X-Forwarded-For header. A good stat program will pick it up and show the IP Address of Google's visitor as the actual viewer of the page rather than the Google IP that's making the request on their behalf. Technically, you should show as the visitor, so your stat program is giving you the correct information and Google is making the request on behalf of their visitor, so their user-agent showing is correct also.
