Why would I not be able to get my web applications to open up on iPad when I am connected via a vpn. we have our apps accessing our services thorough our dmz url we have 10.3.1 arc server... the app is shared publicly. when I turn vpn off I can access my app and services perfectly fine.
Where are the applications hosted? ArcGIS Online or on your own web servers?
It sounds like the network location that your VPN provides access to does not have access to
1) the web server that hosts the web apps(the app would fail to load all together)
2) the ArcGIS Server(the app would load, but services would not display)
