    Hey guys, I hope i found the right place. I picked up a nas200 the other day and i loaded 2 1tb drives in it. I got it all set up and working great on my home network. The reason i bought it was to access and save files on the go.Well for the life of me i cannot figure out how to access this thing from the web (outside of my network, Like from work). I spent a few hours on it. I have a dyndns account and want to use that. I though since i have set up many IPcam's this would be easy.. boy was i wrong. Sorry if this is a noob question guys!!! I read around and i cant find any info on it (that i can understand at least). I just cant figure this out... can anyone help me??let me know if you need any more information.

    p.s.... please explain your answers like you im a complete NOOB..... because i guess i am lol

    The only way to get upload+download access to the NAS with the original firmware is through SMB (Windows file sharing) or through FTP. The web GUI provides access through HTML but that's read-only (and kinda clunky if you ask me).

    FTP will NOT work if you have the NAS installed on a LAN that's connected to the Internet via a firewall, and you're connecting from another network (e.g. at work) where there's another firewall. For details on why this will not work, google for "FTP over NAT" (without the quotes. No, NAT is not a typo).

    If you want access to the NAS200 from the Internet, through a secure connection, you can install my firmware. The latest version is "Jac4" available from this forum. I know it's pretty old but it still works. The firmware is pretty much the same as the stock firmware but it lets you connect to a secure shell which supports SCP (Secure Copy Protocol). The web interface is the same as the stock firmware and it's easy to install the stock firmware back in the same way as you install my firmware.

    So the steps are pretty much as follows:
    1. Install Jac4 on your NAS and follow the instructions to change the root password.
    2. Either change your NAS network settings so that it always uses the same IP address, or change the settings of the DHCP server in your firewall so that it reserves an address for the NAS. This step ensures that the NAS200 always has the same address on your LAN.
    3. Change your firewall so that it forwards port 22 from the Internet to the IP number of your NAS. Port 22 is used by SSH (Secure Shell) and also by SCP.
    4. If your firewall can update your DynDNS address, let the firewall do it and disable DynDNS on the NAS200 so that DynDNS doesn't get confused. If your firewall doesn't support DynDNS, feel free to use the NAS200 but I don't know how well it works: I always used my firewall.
    5. Write down the public IP address of your firewall and go to work/starbucks/whatever. You should now be able to connect to your NAS200 command prompt by using PuTTY and port 22, using the SSH protocol. If your computer can't find the host name, try connecting to your public IP address, port 22. If that doesn't work, it's possible that your ISP blocks traffic on port 22 and there's nothing I can do about it.
    6. If you can connect to port 22 using PuTTY, you can also do SCP through program such as WinSCP (I tried FileZilla a long time ago but back then it didn't support SCP, only SFTP; my firmware doesn't support SFTP. I don't know if FileZilla has been fixed since then). Make sure the PuTTY connection is closed when you try connecting through WinSCP because the NAS200 will only allow one connection at a time if I remember correctly.
    7. WinSCP will let you upload and download files to/from the NAS200 via a secure (encrypted) connection. It won't go fast because the encryption takes a lot of CPU time, but it works. Make sure the program is configured for SCP (not SFTP) and you log in as root, with the password you set in step 1. You will have to change the configuration of WinSCP so that it knows not to look for group names.
    8. If you have large files on your NAS, you may get error messages about WinSCP's inability to parse the output of the "ls" command: the problem is that for large files that are owned by someone in group "everyone", there is no space between the word "everyone" and the file size when WinSCP asks for a directory list. This can be fixed by renaming the "everyone" group to something like "every1"; instructions are elsewhere on this forum.
    Hope this helps!

    Thanks for the info! I upgraded to your firmware and tried messing with it for about 2hr's.... im still lost. I am sorry to say but i need much simpler instructions. I cant believe there is no walk through on youtube lol. I need like super simple instruction... Like put this in this box.. and put that in this box lol.

    This might be out of my league... any recommendations on a file server that be accessed on the internet and is simple to set up?

    For an online storage solution that's easy to use, you may want to check into services like JungleDisk Desktop Edition. There are other service available (Google for "online storage service" without the quotes) but I only really know JungleDisk and I like it very much.

    JungleDisk is not free: they charge a small minimum fee per month (about $3 for the first 5GB of storage). You can use as much storage space as you want and it will cost $0.15 per month for every additional Gigabyte. You can choose between three data centers where your data can be stored: Amazon USA, Amazon Europe, or Rackspace USA. If you choose to use Rackspace (their parent company) as storage medium, they don't charge you for uploading and downloading files.

    JungleDisk shows up as one or more drive letters on your computer (at least under Windows; they also support Mac and Linux but I don't know how those work) that you can copy files to and from just like another drive. Of course the speed at which this happens depends on your Internet connection speed. I have about 70GB of data archived on my JungleDisk and it took me almost a week to upload it all.

    (Note, I'm not affiliated with JungleDisk or Rackspace in any way; I'm just a happy customer)
