Went through the hotspot setup wizard, and my understanding was that this would "automatically" enable Universal Client / One-To-One NAT. But, it doesn't work. DHCP works fine and all is well, but if I assign an random IP to my system (outside of the hotspot subnet of course) then I get nothing. I can't find any real documentation on this for 2.9. Can someone help please!!

Are you also assigning gateway and dns to your card on pc ? As it only works if all of it is filled in.
