I don't think so.

# netstat -npl |grep 53
tcp        0      0 0.0.0.0:53              0.0.0.0:*               LISTEN
     27882/samba
tcp6       0      0 :::53                   :::*                    LISTEN
     27882/samba
udp        0      0 0.0.0.0:53              0.0.0.0:*
    27882/samba
udp6       0      0 :::53                   :::*
     27882/samba

If I use a public DNS, for example, "dns forwarder = 8.8.8.8" necessarily
must work, right?
