This option allows you to control what address Samba will send NBT client packets from, and process replies using, including in nmbd. Setting this option should never be necessary on usual Samba servers running only one nmbd. By default Samba will send UDP packets from the OS default address for the destination, and accept replies on 0.0.0.0. This parameter is deprecated. See Yes and for the previous behaviour of controlling the normal listening sockets. 0.0.0.0 192.168.2.20
