-please read to the end-

I use Windows programs that provide interfaces to Dropbox, GDrive and 1Drive for synchronization.

No native support for webdav/sftp/ftp/...

I have not yet found any alternatives for these programs with the same range of functions (that I use).

Is there a solution (Linux or Windows) that "pretends" to be Dropbox on the internal network, for example?

(or GoogleDrive or OneDrive)

So I can use the synchronization interface of the program.

Solution should only work in the internal network.

( maybe via wireguard also "external")

• DNS server and other server services available in the internal network

• Setting up an own server for the solution is possible

Currently I synchronize the files with Syncthing and rsync.

However, this solution cannot map all the functions of the program's "internal" synchronization.
