Onedrive for buisness on Ipad

Hi

 

We have an on premise SharePoint 2013 installation and our goal is to be able to put documents on SharePoint and have them accessed from the internet on our iPad.

 

We are currently looking at the OneDrive for business app to help with this but we are not getting anywhere. Every time we put in the url which directs to the F5 it redirects to the office 365 site. I know if I put the site into the browser I can authenticate. Is this possible?

 

I know when connected to edge I did manage once to connect but I'm not how I managed it.

 

Has anyone put in a system to access files on SharePoint through the F5 that could assist me?

 

Regards

 

Chris
