How to stream from Duo to Ipad over the Internet

Basically internet is just a network, so yes that's possible but it depends really on the speed of your internet connection (Ipad download and NAS upload) and the size of the movie you want to play. I believe you can already stream to your ipad locally so you NAS is powerful enough for that ?
If you try to play a 10Gb film that last two hours, you would want 5Gb/hour=1,39Mbyte/s=11,2Mbit/s in upload. Impossible with ADSL. For 700Mb films of 2 hours, you need 350Mbyte/jour=5,83Mbyte/min=0,097Mbyte/s=0,8Mbit/s, so this should pass with ADSL but right to the limit. Also keep in mind that I considered linear transfer which may not be the case since films are compressed and some scenes may require more bandwidth than others.

One way to do this is to reroute FTP ports and connect via FTP (preferably SFTP) via internet. Should also work with HTTP. AFP/SMB are not meant to be used over internet (not that secure) but they should work too. then use a player that can read the format of the file (avi/mkv...) via FTP.
Another one is to setup a VPN server, connect to it then do as you would locally.

The performance bottleneck would not be in the duo - it would be the network connection between the duo and the ipad. Your internet uplink may not be enough, the wireless connection to the iPad might also not be fast enough (depending on where you are).

Maybe try the AvplayerHD app on the ipad. It supports SFTP - one of the methods xeltros suggests. If streaming can't keep up, you can also download the files (if you are patient enough).

Hi, this topic is not closed to me, please.
In my case I have managed to run HTTPs with access validation and expose media to registered users. Issue is that I can play (Mozilla) or download&play (MS Explorer) but I can not download or play using ipad or android device even I can see the link to NAS mp3 over the internet.

I do not want to use FTP or any ipad/adroid applications - just web browser and HTTPS protocol as transport layer.
I expect I need to change some stuff in apache conf file but I have no clue what. I have shell access enabled.

Thanks for any suggestion.

This isn't working on my ReadyNAS (duo v1, pro-6 or RN202). All let me see the mp3 files, but when I click on them with Safari on my iPad it stalls on "loading".

The RN202 works correctly with http - just fails with https. The pro-6 and the duo fail with both https and http.
