SNX and Mobile Access do work properly on R80.10 if you install the hotfix from sk113410. However, from what I understand from discussions w/ TAC and my SE, R80.20 is not yet supported. The hotfix in the SK will not install on R80.20, and the fix is not already built into the R80.20 code, or any jumbo HFA for R80.20. I've heard that it may be coming soon, but until I haven't definitive word, I can't move my gateways to R80.20, which is a shame, because there are other features I would like to leverage that require R80.20 on the gateways.
