I have a Lubuntu machine which I use as my main home file backup.
I have a Wordpress blog which I would like to backup using a plugin. The plugin allows backup to FTP/SFTP, so this seems the best option.
I already have OpenSSH server running on my Lubuntu machine, and have connected to it from within my home network from another machine.
However, I keep getting errors when I try to backup from my Wordpress blog to my Lubuntu machine. I believe now that this is because I was using my home network IP for the FTP Server (i.e. 192.xxx.xx.xx), and of course a utility on the public Web couldn't understand this IP.
How would I go about connecting to my Lubuntu machine via SFTP from outside my home network?
PS I thought it was because of ufw for a while, but my SSH port is allowed through ufw.
Thanks for your help.
