NIS 2012 blocking tethered internet connection

I just upgraded from NIS 2011 to 2012.  Under 2011, I could use my adroid smartphone to tether my laptop to the internet.  Since loading 2012, it is blocked.  If I disable the smart firewall, I can still tether.  I can't seem to find what setting is blocking it.  Any ideas about what setting I need to tweak?

Thanks,
