Just don't forget to verify RDP is enabled in the firewall....

- make sure port 3389 points to the server ip in your firewall
- on the server / Start / right click Computer / Remote Settings / Remote / Remote Desktop check "Allow connections from computers running any versions of Remote Desktop (less secure) / Select Users, add user.
- Start / Administrator Tools / ADUC / expand Sever.local / Builtin / Remote Desktop Users make sure user is added here.
If you wish to make this more secure you can change the IP address from 3389 to 3390 or another port however if you wish to do this open another thread and I'll run you through it.

As stated above if you are accessing this externally then its good practice to change the port from the default.
You can do this either by redirecting from a different source port to the destination port of 3389 (eg external port 3391 to 3389 on your firewall.
Or you can change the listening port on your server outlined here
