    Can I use NoMachine to connect a RHEL desktop to my Ubuntu laptop when both computers are behind NAT firewalls and both have non-routable IP addresses?  Normally this requires a publicly available server in between the two machines, and I don’t see anything like that in the NoMachine documentation.

    I’ve looked at Cloud Server and it seems to require that my remote (desktop) computer be publicly available.  (I don’t want to use a web browser any way.)

     

    Can I do this with NoMachine?

    Yes, that can be done. NoMachine automatically maps the port on the router and shows the IP address to connect to. Here you can find a step by step with screenshots (see the Using NoMachine for remote access to a computer over the internet section).

    More details on how the port mapping works can be found in this article: https://www.nomachine.com/AR11L00827.

     

    Note that all this will work even more smoothly when we will release the NoMachine Network Service (or NoMachine Anywhere, we are still debating what name is the best). With this service the user will not have to care about anything.

    Your first link (“Here”) just points back to this page.

    Your solution won’t work with a corporate firewall.  They will not open any port for this purpose, nor will they expose my workstation via a port.  Also, my workstation doesn’t have a public IP address.

    Other vendors in this space (e.g. TeamViewer, ScreenConnect) have a public server for this purpose.  Do you have a solution using a publicly available server?

    So what you ideally need is the NoMachine Network service above mentioned. It will be perfect for users who either don’t know their IP or are not able to configure their router for whatever reason.

    NoMachine Anywhere is in its final stages of development as part of the version 5 roadmap.
