Port Forward

I have a backup batter at home that is connected to my wifi. It requires that certain ports be open for its application, so that the manufacturer tech support team can remotely access the batter controls. The ports are 232, 1196, 222. I used Port Forward to give the app access to those ports. But the support team is still not able to access the app. It seems that the xfinity model is blocking access. I made sure that Advanced Security is turned off, but that still has not solved the problem.

And I just can't get a live Xfinity person on the line to help me.
