I have an ultra 2. I updated to last firmware. Dd a factory reset. Now I am reinstalling from scratch users, share... I tried to leave as much default options as possible. I do not have any addon but ready dlna, remote and photo. I remark that I am not able to retrieve the directory listing with FileZilla by FTP. I log in correctly but then failed to retrieve the shares and stop. Same with remote, whatever cifs or FTP mode, I login but it fails reading shares. Ready dlna do the same, log in then crash!
I used to be able to connect by FTP with previous firmware. FTP is enable for all shares.
So what is different from using FTP from my intranet? I did specify passive as well. How to correct this behavior?
When you use a passive port, the FTP client asks for the port, and the NAS replies with the full IP address (xxx.xxx.xxx.xxx:yyyy). With the V1 and x86 platforms, you configure the IP address for FTP as the "masquerade address".
Some routers will forward correctly when the external IP address is used from inside the router (on the LAN), others will not. From your symptoms, I am thinking that your router does not.
Some clients (FileZilla being one) will detect if the IP address signaled is not routable, and in that case will automatically substitute the external address from the IP header of the response packet from the NAS. With those clients you can set the NAS masquerade as the internal NAS address, and they will work correctly both on the LAN and over the internet.
BTW, "intranet" is not exactly the right term for most home networks. "Intranet" is a network of LANs, generally used to describe corporate networks.
I just want to update the thread by saying that now Remote work on my iPad.
What I did is simple but I could not imagine it. Actually I reset the network and parameters of my iPad then everything started to work by FTP and CIFS mode.
