Thanks; if it listens on localhost by default, that is enough for me,
though I recall that is not as secure as listening on 127.0.0.1. I never
really used iptables much and am not using it now, so I do not think I
will need to do. I do not see why I cannot just turn off the port
usage, since I have root access and only ever use NUT from a shell.
