See if the port is open from the outside.

#1 This could mean using a port checker.

An example of a web based port checker, is

If you use a web based port checker, be sure that:

the server is in the listening state and you are forwarding the ports that you want to check.

If you use an inbound client side port checker like http://www.pcwintech.com/simple-port-tester or from https://portforward.com/help/portcheck.htm then be sure that:

you are forwarding the ports that you want to check and the server that you are trying to forward is NOT in the listening state.

Stated reason that the server that you make sure the server trying to forward is NOT in the listening state when using an inbound client side port checker, when using this kind of port checker - it will try to listen on that port and you can not have two servers listening on the same port at the same time.

#2 Or you can have someone try to connect from the outside. When they do this, it does not have to be for RDP if desired - it just has to be server of sorts.

#3 Once you know that the port is open from the outside (not talking about from behind the router), see Port forwarding only works seen from outside my local network?
