This is a cross-post from Superuser where I was unintentionally off-topic
We are a small office which deal with large amounts of sensitive customer files. Recently our governing body restricted use of cloud services such as Dropbox, Google Drive, etc. I have been tasked with finding an alternative solution and am coming across some issues that I would greatly appreciate some help with.
I ordered a static IP from my ISP and connected a hard drive to the router. What I currently have set up is that someone at their home office can log in to ftp://207.XXX.XXX.125 (X's are actual numbers obviously), log in with username/password, and access the files via FTP through my router. This works for being able to access the files remotely, however there are some quality of life problems for people who are used to Dropbox.
For instance, if you have the Windows Explorer open to the FTP (it connects through "The Internet/207.XXX.XXX.125/All/Filepath") and drags a file into Gmail, all that gets dropped there is the filepath instead of the pdf. Windows also seems to run into issues remembering where the file path is so the users have to constantly plug in ftp://207..... in order to access files.
Perhaps you can help me with a solution. Ideally I am looking for local document storage which can easily be accesssed by Windows or Mac by utilizing my office Static IP.
I've done a ton of research but I feel like I'm just banging my head against the wall constantly. We have no problem throwing some money at the problem as long as we have control over our files, it is secure, and some QOL adjustments are met.
