Feature service not aviavble in ArcGIS online and Collector when not connected to the network

Question

So i have two services hosted on my server, one is feature service set up for editing and the other is map service.

Im using these services in AGOL and Collector for GIS. im am using the REST Service through my webadaptor not the local 6080.

When i am work and connect to our work WIFI network everything works perfect however soon as i get off the work network and on to say my home network i can not connect to the map in ArcGIS online or in Collector, when i try it say  "<feature service> not available NSURL Error -10003".

So thoughts?

TL;DR

ArcGIS online and collector can connect to hosted service when connected to the work network but not when connected to a non work network.

ArcGIS server 10.3.1, Collector for ArcGIS OSX

If you want to expose your services to outside world, you have to setup DMZ(demilitarized zone sometimes referred to as a perimeter network)

i am think you might be right but i though the web adapter was supposed to get around this, ie make it so that your services could be available to people outside the network?
