Fritzbox nas server fernzugriff + create drive?

I wanted to ask if anyone knows how and if I can create a normal drive with which I can access the Fritz Nas.

I know that you can do that while you're in the same network, and I can handle that as well, so I can access it via MyFritz and a browser and FTP

My concern now is that I can access on my laptop at home on the Nas server work and I have a normal drive for this, without me on a Ftp program, or access it via the browser on it.

As soon as I'm in the company, it is with the \ fritz.box user and password enter, that works, I need that now only that it works well when I'm no longer in the company but at home.

Because it's about company data, only VPN is a solution. But of course someone has to set up work and then everything on your laptop to be configured.

Data protection law, these data (private and professional) to separate.

You can do this with a site-to-site VPN and share in a network drive. This works well with the Fritzbox and Shrewsoft.

I would not recommend it. And so will the admin in the company also see.

I think this solution is quite good:

Of course you need DynDNS:
