Looks like the rules where made but not applied
Look at step 6http://www.pcwintech.com/2wire-generic-guide-2-all-models
So here is what you do. Since you have 3 machines you will do this 3 times.
At the top of the page you will click on the machine name for the first machine.
Then click user defined, then in the list choose the rule and click add.
Once done click save.
Now do the same thing for the other 2 system names up top.
Once that is done run my port tester program on one of the machines, only test the port that is going to that machine.
The port tester opens and listens on the port on the system SO testing the other ports will fail since they are pointing to the other systems
