How to ssh into android behind NAT?

Question

Android

Tell me how and with what application to log in via ssh to your android which is on 3G?
In theory, I plan to break through the NAT of the cellular operator with a reverse tunnel from the android to my router, and I myself will log in to the port of the home router. Android without root.
Tell me what applications from the market to put on android so that you can implement this?
