I have the following ifconfig:-
enp0s31f6: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 10.21.0.11 netmask 255.255.240.0 broadcast 10.21.15.255

TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
Also my /etc/network/interfaces looks like this:-
# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback
To assign a static IP i tried to add something like this from here:-
auto enp0s31f6
iface enp0s31f6 inet static
address 10.253.0.50
netmask 255.255.255.0
network 10.253.0.0
gateway 10.253.0.1
dns-nameservers 8.8.8.8
I save it with sudo and then on terminal type and enter: sudo ifdown enp0s31f6 && sudo ifup enp0s31f6. This does not work. The goal was to enable nomachine access to this server machine from an outside client network. Doing this step led to loss of connection with the server immediately. The above ifconfig results is greek to me and i copied pasted from above SO answer. How to make this work? What are the correct values i should have given for the fields address, netmask, network, gateway.
