Hi,
I just thought i'd follow up on this post and results so far.
I have a new ASUS RT-AC66U router which is attached to my NAS - the router has a couple of interesting functions on top of the usual functions such as AiCloud and AiCloud app accessable USB ports with remote access capabilites.
After a small amout of tweaking my registered users are able to access the NAS to view and stream using either the iOS or android download - phones & iPAD etc. They are also able - once set-up - to access the NAS remotely through the AiCloud function - this allows users to access files, download and upload and change names where their priveledges allow.
1. I am still investigating the security implications so have limited files available through remote.
2. There is also a certificate issue when using AiCloud from heavily protected networks.
3. Some Mac's are unable to log onto the domain using AiCloud - not sure why yet.
4. Mobile devices are unable to access the AiCloud through a browser as the pop-up password box does not display correctly.
It seems to be the solution to my original question.
Thanks to James W for his time and patience with me.
John.
