Hi Albert,

Thank you for your suggestion.

A --no-dns-interface option would be what I need :-).

Unfortunately, samba seems to have the port 53 hardcoded (found a 
mention of this on the net). I have tried to append a different port 
number to the address samba uses as its DNS forwarder (and having 
dnsmasq listening on that port), with no success.

I guess I will have to redirect all queries from samba to its DNS 
forwarder on port 53 to another port and have dnsmasq listen on it, as 
suggested here:

(I forgot to put the link in my first post)

But that will be another step on the path...

Thanks again and regards
