Not the NetBIOS packets themselves unless you explicitly try
and access machines that would lie beyond the link - but other
NetBIOS packets on your network can generate side effects...

...like that :-). If 195.170.129.129 is running samba it is
probably nmbd that is trying to satisfy a strange WINS name
look up by querying DNS. If so then reasonably up to date
versions of samba have a config option that will disable
DNS look ups of WINS queries. In most cases this doesn't
break anything - unless you want people to be able to type
in Internet host names to, say Network "Neighbourhood" and
access shares on distant machines.
The best way of controlling DNS queries is to run your
own named using the "forward" config option to have it
talk to your ISP's nameserver (not essential if you have
a valid root.cache but definitely "net friendly" :-) )
and then point *all* you internal machines at your named
rather than your ISP's. Then you can use the query log
feature of named to see exactly what look ups take place.
If you want to kill some of the, ah, "damn stupid" look ups
you can make your named authoritative for some domains so
it can return "up yours" responses without having to ask
your ISP first.
