Question

FTP 425 Can't open data connection.

Asked by: ccampbell15

Im trying to make an FTP connection using Filezilla. On both the client and Server side I am
using Filezilla. The Server is running Server 2003. The firewall in the router is dropped. The
router is a wrt54G running DD-wrt. Ports 21 and (1024-10000) are forwarded to the Server. I
plan to use a range of 6000  6100 once I get this working.  Using Filezilla server 0.9.32

On the client side I am running Server 2003 and the router is a Buffalo also running dd-wrt. Its
hardware firewall is dropped. Ports 20,21 and (1024-10000) are forwarded to it. The ISP is
roadrunner on Time Warner (both ends) and from I can tell they dont block anything. Using
Filezilla client 3.2.7.1

Im pulling my hair out over this!  No documentation I can find, other than the obnoxious Read
the  Network Configuration Guide., even points me in the right direction. The Network config
guide just says to throw away all routers. Yeah right.

I get this error with multiple clients.

Update:

I get a slightly different error when using CuteFTP as a client. It cant find the directory or a perms issue. Im not sure which of the two. The folder c:\backups\tholen does indeed exist and ntfs perms are full for lee.

I assume my Filezilla Server is hosed but dont have clue whats wrong.  With the routers using dd-wrt and the firewalls dropped I dont suspect an issue there.

when using FTP you can't specify the drive letter.  On the ftp server you need to setup a virtual directory that points to the real location and then just cd to the name of the virtual directory.

So you might setup c:\backups\tholen with a virtual name of \backups4tholen  then you would issue the command:

   cd \backups4tholen

and the ftp server will put you is the correct directory.  ftp was developed in environments (unix based or unix like) that don't have drive letters, that's why you can specify them.

As for the other problem where you could not estiblish a data connect, if it is still occurring then you need to make sure that your firewalls are ftp aware or on the firewall protecting the ftp server you have to allow all high ports (>1023) inbound to the port range 6,000 - 6,100 (the range your ftp server is using for passive data connections).

Oh, I fixed the issue by replacing filezilla. Using cuteftp as a client and winftpserver. winftpserver offers me a virtualname which I could not find in filezilla.  Replacing the client just fixed the data connect issue. The explaination of the pathname was great. TY
