Then why is Samba replying to NetBIOS broadcasts very nicely when I put
it outside jail (with the same configuration)? As far as I understand
Samba also provides resolving - NetBIOS resolving via its nmbd.

Okay, let me clarify all this once again: I know that this will work for me.
I also know that if I add a mapping "machine" -> "IP address" into my DNS it
will work for me. I also know that if I turn on WINS support in smb.conf and
then set up a WINS server on the Windows machine, it will work fine.
But as you probably know, there is also a "third" way of resolving names to
IP addresses - it is called NetBIOS broadcasts - from Wikipedia:
"In order to connect to a computer running TCP/IP via its NetBIOS name, the
name must be resolved to a network address. Today this is usually an IP address
(the NetBIOS name-IP address resolution is often done by either broadcasts or
a WINS Server — NetBIOS Name Server)."
So it says _either by broadcasts or a WINS Server_. I don't want to use WINS
server (or DNS server) for this, but NetBIOS broadcasts. And these broadcasts
work just fine when my Samba 3 server is not running in a FreeBSD jail. As soon
as I put it into the jail, for some reason, Samba 3 stops responding to NetBIOS
And this is what I would like to understand - why Samba 3 stops responding to
these broadcasts when it is running in a jail.
