connection refused when I try to connect client with server

Question

I made a basic client / server datasnap applications and it work in local network through http but when I tried to connect from the internet I get connection refused, here are the steps I followed:

I set at the server component TDSHTTPService to connect through port no 8081 then in the client I set to use same port in TSQLConnection component, and I used my PC public IP in the HostName but when I try to connect I get connection refused.

Any advise ?

Forgot to say the client is Firemonkey app running on Android.

You should go to router admin console, find something like "port forwarding" and route the port (8081) to your computer IP - you have to say the router that traffic on this port should go to your computer
