Windows shortcuts, Macintosh aliases, and Unix symbolic links,
are all different. A Mac in the Finder, can follow both Aliases and Symbolic links but not Windows Shortcuts. Are you sure it is a Symbolic link? This would have to be created either on the Mac in Terminal.app, or on the ReadyNAS itself if you have enabled SSH access. A Windows client would not I believe be able to create a Symbolic link (unless it logs in the ReadyNAS via SSH).
Yep, its symlink. I modified samb.conf, restarted samba (as I wrote above) and them created symlinks via Mac over SSH.
What I can't understand is that same symlinks works on Windows, Ubuntu and ElementaryOS but not on ML...
On my old NAS (Streamed eTrayz) I had same HDD setup/folder setup and symlinks worked fine on all OS.
I have created and used Symbolic links on my ReadyNAS via a Mac and they work fine but I have not tested them under Mountain Lion. I used the ln -s command. The difference in behavior might be down to 'hard' and 'soft' links (i.e. using or not using the -s flag).
