I have an iPad with an Orange Data sim and I want to connect to a VPN when I'm out and about over 3G. I have the tunnel end point defined and the connection works when using a WiFi connection, logging me on and giving access. However, when I try to connect over Orange 3G the connection fails to establish, showing 'starting' then reporting 'a connection could not be established...'. I have two VPN's defined to different locations and neither work on Orange 3G. If I use a borrowed O2 sim, then voila, all is okay. Orange say the issue is with the remote location.
