How to setup real SFTP in Yosemite?
There's lots and lots of information online about how to setup remote access to my mac using SSH and SFTP in Yosemite...but apparently none of it is actually useful for genuinely remote access...access from outside my network, access from miles away. Because here is what I have learned:
The ip address listed in the Sharing pane when you access remote login is internal. it's some version of 192.168.x.x, which is essentially everybody's computer and utterly useless from outside the network.
So my actual public ip as assigned by my service provider is really my IP if you are trying to get to my computer from outside.
But that IP doesn't "just work" via SSH or, much more importantly for me, SFTP. Evidently that involves something called "port forwarding" which one used to be able to do via Airport Utility, but is no longer possible because such options do not exist in the current version of the utility.
(What I want to achieve is for a friend of mine, a friend on a mac about 4 miles away, to be able to directly access very large files on my computer. I don't want to use clouds or public sites or anything like that, I just want to be my own private little FTP server just for her. That used to be no big deal.)
So... is there a solution for this?
