Hi All,

We've just rolled out a TMG 2010 server, It acts as a transparent proxy and all works fine for both HTTP sites and HTTPS.

The problem we are having is with the IPAD2:

Youtube App error: 'Cannot connect to YouTube' - Note: the actual YouTube site works fine, through safari
App Store error: 'Cannot connect to iTunes Store'

Im pretty sure both errors are related. After trawling the internet the nearest report & solution of this problem i can find is the following:

Which suggest to enable "Allow range requests through unmodified" on Watchguard equipment - Is there an ISA/TMG Equivalent setting?

Any help greatly appreciated.
