     If they have set up port forwarding for you already then that is different.  In that case, then you could be experiencing the bug with the most recent release of ARD (3.7.2) and in particular ARD 3.7.2 and Yosemite ARD version 3.8 clients.  It has been reported numerous times in the forums and to Apple that since 3.7.2, clients are frequently unavailable to connect to despite there being no network issue between the remote computer and client computer.  I have not seen anyone report it who was working from outside the LAN to inside the LAN, but I have the same issue with a number of my own computers that are simply on a different subnet, so it stands rot reason that it would happen from a port forwarding location.
     I am sometimes able to resolve the issue locally by SSH connecting into the client computer using Terminal on my admin machine and restarting or relaunching the ARD agent on the remote device, then trying to connect to it again after about 30 seconds.
The Terminal commands for this procedure are as follows, though you might need to include a port number from outside the LAN:
First:
ssh ipaddress -l adminusername
(example: ssh 192.168.1.1 -l macadmin)
Second:
sudo /System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/Resources/k ickstart -restart -agent
After that, waiting about 30 seconds and trying to observe or control usually works, though the computer may still fail to show an online or lit-up status indicator.
