[Samba] VPN and NetBIOS Name Service

[shaunp]

Hello, I'm running a Samba client on Mac OS X 10.3.9 and Samba works fine when
the Mac is at home (e.g. file transfers, name resolution, etc.).  However, name
resolution does not work when the Mac is at a remote location and logged into my
home network via a PPTP VPN.  File transfers work fine over the VPN connection
when I use IP addresses instead of NetBIOS names.

While trying to debug the problem I ran WireShark to sniff packets on the Mac
and found that Samba does not broadcast the NetBIOS Name Query across my ppp0
interface.  Since ppp0 is dynamically created on the Mac when it connects to the
VPN it doesn't appear that I can set ppp0 as an interface in smb.conf to solve
the problem.  Is this correct and, if so, what do I need to do to tell Samba to
broadcast NetBIOS Name Service traffic over dynamically created interfaces?

Thanks,
Shaun
