Google Earth through Smoothwall

Anyone using Google Earth through Smoothwall if you are can you tell me what you unblocked to allow it to work?

If I just point a PC at the EMBC proxy GE works fine but when I point it at the Smoothwall I get an authentication error.

Thanks.


EDIT

Ignore that for some reason this last time I launched the program it generated a useful message with the URL, kh.google.com

For future reference, the live log is really handy for diagnosing this kind of problem, it tells you exactly what it's denied.

Hm. Sounds like it could be not wanting to authenticate via NTLM (which is what I assume you are using). Let me have a fiddle with it and I will let you know.

Meanwhile, log extracts would be useful.

The Smoothwall will be my problem soon (someone else manages it mainly at the mo) so i'll no doubt i'll have to read up.

The live log looks interesting.

Thanks.
