    My domian server is windows server 2008 r2 and recently NAT is installed and configured. All the client workstations are windows 7. Our client machine trying to access a FTP site at different location through Filezilla and it is failing to establish the connection.

    Here is what the connection process shows

    Status: Resolving address of "    "

    Status: Connecting to "IP address" :21

    Status: Connection established, waiting for welcome message...

    Response: 220 ---------- FTP server ready

    Command: USER ---------

    Response: 331 password required for -------

    Command: PASS ************

    Response: 230 User ------- logged in

    Command: FEAT

    Response: 211 - Extensions supported

    Error: Could not connect to server

    This is where it stops. Could somebody tell me what is causing it. If I try to connect to the FTP server from the domain server it successfully connects.

    Try with internet explorer to rule out if it's filezilla that make a bug.

    PASV mode setupped to enable it to pass the NAT'ing ?

    Hey buddy, try setting Filezilla to Active Mode.

    Go to Edit / settings/ FTP then select Active mode

    I don't have any luck with changing the Filezilla setting to Active mode.

    My clients are connecting to the internet through a Cisco WRVS4400N router. It could be some settings in the router, I beleive.

    The FTP connection is working through Internet Explorer, but not with Filezilla or from windows explorer. I can't figure out where the problem is.

    1. have you test locally in your LAN using FTP private IP, whether you can successfully connect to your ftp?

    2. Did you open port 21/20 in your windows firewall?

        20 - TCP - Data Transfer

        21 - FTP Control command

    3. If you can connect successfully through your LAN, have you set the port forwarding on your CISCO router to the private IP address of your Windows 2K8 server.

       ***NOTE**** If you setup port forwarding on your CISCO router to your Windows 2008 server, make sure you port forward only port 20 and port 21.

      If you accidentally make a wrong configuration in your Cisco router and open 0-65535 ports you're definitely in trouble.

    ask your network admin to configure the port forwarding sample below:

    ip nat inside source static tcp windows_Server_private_ip 8080 public_ip 8080 extendable

    Good luck!

    Every second counts..make use of it.
