An issue was found in 1.5.6 that calls for an early next release to fix that. Find the details here if you run into problems with FTP connections on kernel updates or storage nodes in 1.5.6: https://github.com/FOGProject/fogproject/issues/311
@Razuel remote management is what it sounds like. Public facing meaning the fog server is accessible from the internet.
While technically possible to image, it really wouldn’t be the best experience. By remotely managed we simply mean you can change the host name, tell it to join a domain, configure printers, set up snapins, and that kind of thing. I wouldn’t recommend imaging over the internet as it would be constrained by your internet upload speed and the remote sides download speed.
Usually download speed is fine anywhere but upload is typically limited much more so.
