I installed the deb 6.11.2 version of NoMachine on my Ubuntu 18.04 machine using the command
sudo dpkg -i Downloads/nomachine_6.11.2_1_amd64.deb
I now can only connect locally and no external IP address is shown. Upnp is enable on my router and in the server.cfg file. The command
sudo /etc/NX/nxserver --upnpstatus
shows only addresses for Local and Gateway while the External is blank. When I run the command
sudo /etc/NX/nxserver --upnpmap
nothing is returned after running for several minutes. I am using the Negear nighthawk R6400v2 router.
One other thing that I have noticed that may or may not be normal but I have NX directories in both my /etc and /usr directories.
Any advice is appreciated.
