Be mindful of the order of the allow and deny statements.

My fault, I mistyped it.

The official /etc/services entry:

nut             3493/tcp    # Network UPS Tools

It should be listed, but maybe netstat is truncating it (this
sometimes happens with the longer IPv6 addresses).

It's a moot point, though - the port is open, or else upsd would not
be logging the error messages. See Arjen's comments.
