Is it possible to implement communication via the Internet in a DataSnap project?

Question

Delphi

digital-flame.ru/2015/09/01/delphi-datasnap-sozdan... according to this article I made a client-server, I try to connect via wifi, everything works fine, there is a [email protected] router, through no-ip and substitutions in the local ip networks from 2ip servers do not give any sense. the application, as I understand it, hangs on 192.168.1.2 and the router is on 192.168.1.1, so I get through the same no-ip to the address of the router 192.168.1.1 and how to get to 192.168.1.2 can it be in the project where it is configured ??? I don't understand at all
