OK well I found this documentation. When you close down gufw and start it back
up, the firewall is showing as OFF. It doesnt say how to keep the program
running as a startup application either, nor are there options in the gufw to
keep it running. I am aware however of starup apps but what could I do to ensure
it turns on everytime automatically? What has everyone else done and how do they
know its working?
