So my Ubuntu 14.04 doesn’t display the external addresses, so I can’t access it from outside the local network. When I try to tick the Gateway port from the server preferences I get the message:
“Failed to map the port on the gateway”
As I have understood from the other topics, this is mostly likely due to the fact that my router doesn’t support UPnP and NAT-pmp. This is in the test environment though. I don’t know yet, what is the router I will actually use in front of the server. However, I will have access to configure that router.
My question is: Will it be possible to use NoMachine for remote desktop over the Internet, even if the router doesn’t support the UPnP and NAT-pmp, if I configure the port forwarding correctly on the router? If this is possible, what other configurations should I do with the client, server and the router?
Thank you for your help!
