Forwarding traffic over a tunnel like this can be problematic, as
different MTUs etc. can result in dropped packets and other odd issues.
 IIRC OpenVPN doesn't normally tunnel broadcasted traffic either, but
that's usually only used when trying to connect to the machine in the
first place.

If you get an access denied error it would seem that the connection is
fine, but for some reason you end up connected as a different user.
When this happens I would temporarily grant full access to the share
(chmod a+rwx) then create a new file.  If you look at the file on the
server you will see what user and group it was created by, and
presumably this user didn't have access to rename the original file.

If that's the case it means you'll need to investigate why suddenly that
user has no access, or why suddenly you end up connected as a different
