TCP port forwarding for node

I paid for the $5 subscription for localxpose for my account trying to do this, 

https://node-pi.com/pinode_eng

It is the installation of a pi node which requires port forwarding of the shown ports in the link above.

My ISP is blocking these ports as a result of using a restrictive firewall/CG-NAT that prevents the ports from being forwarded, so I was looking for solutions and I found localxpose which was promising. Now I am trying to open the ports 31400, 31401, 31402, 31403, 31404, 31405, 31406, 31407, 31408 and 31409 using TCP protocol without success.

Is it possible to use localxpose as a solution to this problem and if so how do I do it?
