Setup ftp with DynDns

[michaelof36]

So I bought a My Book World Edition today (if you don't know its a NAS) and I wanted to set it up using a dynamic dns to allow access for ftp. It comes with some crap software called Mionet that does this but I try to stay away from manufacturer supplied software. Can someone guide me in setting up my My Book for ftp access using dyndns? I have it setup currently through my router and can access the drive on the computer so far. I also registered with dyndns.org.

I have my DynDNS through www.noip.com

All I have to do is keep the current IP address of the FTP updated on that website.

Then just put your DNS address in your FTP Server settings, and you should be good to go. Also, it might be a good idea to configure it with a high port number, and then open that port in your router.

Well, the only reason I set it up through dyndns.org is that my router automatically syncs the ip for the ftp. I'd much prefer to keep it this way...

Someone correct me if I'm wrong, but if you have dyndns setup, all you have to do is forward the ftp port (21) to the IP address of the NAS.

^ yeah thats pretty much all there is too it.

Well i forwarded port 20 according to my router (for the NAS) but I still can seem to log in through filezilla. Anything I'm missing?

Edit:

Am I supposed to add the ip of the NAS somewhere to redirect it? I know in dyndns.org setting it has my external ip address only...

That's what port forwarding is... Its forwarding the data coming through a specific port to the IP address specified.

forward the ftp port (21) to the IP address of the NAS.

"Well i forwarded port 20 according to my router"

Where did you come up with 20?? 20 is the data port, 21 is the control port.. You need to forward 21, not 20.

Here is a great write up in understanding how ftp works, both active and passive modes.

edit: Also -- your going to need to test from the outside.. Trying to hit your public IP from a inside box may or may not work, depends if the router supports loopback forwarding, also known as nat reflection, etc. And with ftp can even be more of an issue -- see the active vs passive link I posted, etc.

FTP through nat can run into some problems.. But your going to want to test it from the outside, once you have forwarded the correct port.

I work on the DynDNS Ninja Squad (aka: support team). The easy part is actually the DynDNS part, which just requires pointing your hostname (example.dyndns.org or whatever you name it) to your IP address. Then you tell your update client (your router) to keep this hostname up-to-date.

Once you get that done, you just need to do the port forwarding part (port 21) on your router to your NAS' private IP address (usually something like 192.168.x.x). You can test the port forwarding to see if the port is open by using this tool:

Assuming it is all configured properly, you should then be able to enter your hostname in your FTP software and connect to your NAS.

One stumbling block you may run into is if your ISP blocks inbound port 21 traffic (I have seen it happen with some customers). If that happens, you will have to configure your NAS and the port forwarding to use an alternate port, then specify this port in whatever FTP software you are using.
