[Nut-upsuser] Master Works, Slave Does Not

I would like to verify my understanding keeping in mind I have a one master and one slave computer.
When the master gets the low batt/noAC signal it initiates a broadcast packet(s) on port 3493.
1) Is this correct?
Then the slave computer must have this port open and it listens on this port for the shut-down command.
2) Is this correct?
On the slave if I run the following:
steve at MyDesktop:~$ nmap -p 3493
Starting Nmap 6.40 ( http://nmap.org ) at 2014-11-09 15:42 ESTNmap scan report for is up (0.00013s latency).PORT     STATE  SERVICE3493/tcp closed nut
Nmap done: 1 IP address (1 host up) scanned in 11.06 seconds
Which tells me this port is configured for nut but it is closed?
I have rebooting and starting and stopping the service using:
sudo service ups-monitor stop 
sudo service ups-monitor startBut it remains closed.
3) Assuming this should be open how do I fix this?

Thank you for any help - Steve
