The computer that I want to connect to is connected to the internet via an iPhone hotspot.  I don’t think it supports UPnP or NAT-PMP.
After looking around, I think what I need is the NoMachine Anywhere product.  What is the status of this product?  Is it already in version 5.0.53_1 for Linux and I only need to turn it on?  If not, what is the expected road map?
Thanks!
