I'm assuming this is a bug, as it worked before.

I have a WinXP VirtualBox guest that I like to share folders with via
samba (please don't suggest using the VBox shares option as a
workaround).  In the past, I was able to restrict access to just the XP
Guest via

hosts allow = 192.168.56.0/255.255.255.0

in the smb.conf file, as the vboxnet0 interface is on that IP range
(it's 192.168.1.101).  "bind interfaces only = true" is commented out,
as are all "interfaces" lines.  At some point (I'm not sure when, as I
don't use the XP Guest that frequently) this stopped working.  If I
comment out the hosts allow line such that access is available for
everyone, then the XP Guest can connect.

I have the same problem if I comment out "hosts allow" and have

bind interfaces only = true
interfaces = lo vboxnet0

The first setup listed has worked previously, so I'm filing it as a bug.
Again, by simply changing the smb.conf by commenting out the "hosts
allow" line and restarting samba, I have access to the shares (so the
shares are being put up properly), and I'm asked for my samba username
and password when accessing from the guest, so I think that end of it is
behaving properly.  There seems to be something wrong with how it's set
up to filter on IP or interface.
