Trying to connect to NAS

I have a TP-Link WR842ND router which has a USB drive to which I have plugged in a 2TB HDD and set up file sharing in the admin menu (192.168.0.1) and also FTP, it has given me 192.168.100.103 as the access IP address.

I can access the HDD via my PC's no problem from the 'Libraries' page under 'Computer' on Windows 7, however I would like to play the movies on the HDD from my M3, the M3 is connected to the router via Ethernet cable.

From the M3's menu I went to USB >> file transfer up/down >> create new (yellow button)
You have to enter the IP address of the server, so I entered 192.168.100.103, when I try to connect it says 'trying to connect to server' then after a few seconds 'connection failed'?

I am not sure what I am doing wrong.

I have another router connected LAN to WAN from the primary router which has the IP 192.168.1.1 for which I have a VPN installed.

The M3 is connected to the internet okay for c/s etc.

Any ideas to what I am doing wrong?

Hi

Not sure I can directly answer your question, other than to say when I set my NAS up to share individual folders over several
device's,I set each device with a fixed IP adddress I then set permissions on NAS for each device allowing read/write ext with regards to each folder ie Movies,Music,Picture and so on.
I also set NAS for NFTS,FTP and I think Samba ( not at home going of memory).
This works for wired and wifi.
With having a large number movies,TV series with metadata the TM M2 didn't do the job for me, I now use a MINIX Neo 8H and a MINIX Neo 8H Plus box for IPTV and streaming( just in case) with this system I no which movies have seen and TV Series coming up.
Hopes this is some help.
