ftp refusing connections

Question

Hey all-&nbsp;I'm curious what the most typical reason is for the standard ftp server loaded on these nas devices to 'refuse connections' ?&nbsp;Here's the messaging that I'm getting via a filezilla client when trying to connect:&nbsp;Status: TLS connection established.Status: Logged inStatus: Retrieving directory listing...Status: Server sent passive reply with unroutable address. Using server address instead.Command: MLSDError: The data connection could not be established: ECONNREFUSED - Connection refused by serverThanks for your thoughts

It sounds like you are connecting remotely (over the internet) - is that correct?
&nbsp;
If so, you normally need to&nbsp;

set a much smaller set of passive ports (perhaps 4 per expected simultaneous connection)
forward the passive port range in your router to the NAS

&nbsp;
Did you do those things?

Thanks for the help!&nbsp;I am trying to connect over the WAN (internet), yes.&nbsp; I guess I need a lesson on port forwarding when it comes to ftp.&nbsp;&nbsp;I do have the default ftp port (21) forwarded to this particular NAS- the one running this ftp server.&nbsp; I've also set ftp to disabled on the share listing, but have enabled certain users (two for read only and one for read/write).&nbsp; I've listed a 10 port range in the admin screens of the NAS / ftp server settings, but hadn't yet forwarded that port range in my router- I'll try that now.

I'm beginning to think that my issue is more with FileZilla than it is with my network and/or NAS settings.... I've just tried logging in with an android app called ANDFTP and it works fine.... not sure- maybe my FileZilla version is old or for whatever reason not playing nice with the NAS server...?

So I've forwarded the 10 port range for passive use (from my router to this NAS), and I've gone into a different NAS that I had running on our LAN and killed the ftp server (thinking that it might be causing some confusion to FileZilla), but am still having trouble getting FileZilla to be able to connect properly.... not sure why...

The original&nbsp;Status: Server sent passive reply with unroutable address. Using server address instead is because you don't have masquerading set on the NAS. &nbsp;That's a convenient FileZilla feature, as it allows you to use FTP on both your local network and remotely.
&nbsp;
-Have you checked local FTP access?
-Have you double-checked that port 21 is forwarded to the ReadyNAS and not the other server?
-If you are using FTPS, you need to set FileZilla to "require explicit FTP over TLS".
&nbsp;
You might also confirm that the passive ports are all open (with canyouseeme.org for instance)
