Description

We are using FreeNAS with multimple intefaces (2), and due to security issues, I only want Samba to listen on 1 of the IPs/Interfaces.

When Bind IP Addresses: option is selected, samba is only configured on this interface:

root@fuen-dc-1:~ # grep interfaces /usr/local/etc/smb4.conf
    bind interfaces only = yes
    interfaces = 10.0.3.20
root@fuen-dc-1:~ #

But per samba recommendation a loopback (127.0.0.1) interface must always be included, as lack of this can cause some issues to internal scripts and other samba utilities. And Loopback is not available in the list of interfaces/IPs to choose from.

As a workaround, I've set this options through Auxiliary parameters:, but Loopback should always be active, as per samba team recommendation.
