    Re: FTP connection not possible

    Svenster,

    After 22 posts you should know that we require more information before we can help you.

    What version of windows are your running?
    Are you using IIS?
    Do you have any routers?
    Is port 21 forwarded to the correct server?

    the more info you supply the quicker we can help you

      Michael,

      Sorry you're right...
      I'm running Windows 2003 standard. The gateway server is a SBS2003 server.
      I do use IIS for publishing the company's website and OWA.

      I just finished moving my SBS server from old hardware to new hardware. Before that FTP was working from every computer or server in the network. Currently I have no firewall or routers configured in the network.

      ISP Modem > Gateway server > Network

      That is how the network looks like at the moment....

        Moved to the SBS forum.

        try to telnet to your SBS server and see if port 21 is open i.e.

        telnet <servername> 21
        the FTP service should respond.

          Telnet to the SBSserver does work. FTP on this server is not the problem, it works. The problem are the servers and workstions behind the gateway server. From there its not possible.

            Re: FTP connection not possible

            So your saying that you can FTP to the server from an external address but you cannot telnet to the server from an internal address?

              FTP from and to the SBS server (gateway) is possible.

              FTP from and to the other server and all workstations in the network is not possible.

                Re: FTP connection not possible

                Why would you want to FTP from a server to your workstation? Why dont you just FTP from your workstation to your server and bring the files down?

                Sorry if I'm misunderstanding your questions

                  Re: FTP connection not possible

                  On 1 of my servers we use some database software from some company. This software can automaticly send error report to that company via FTP. The FTP connection is somehow blocked.

                  To locate the problem I tried to connect to ftp.microsoft.com from this server. This doesn't work either.

                  Next I tried to connect to ftp.microsoft.com on my gateway server (This happens to be a SBS2003 server). This does work!!

                  Conclusion: FTP does only work on my gateway server and not on any other computer or server in the network....

                  Hope I discribed the problem more clearly now !

                    Re: FTP connection not possible

                    So if I understand you correctly you've the following situation (I'm a bit lost)

                    Connecting to the FTP service on the localhost gaves no issues.
                    Connecting from an internal client gives you issues (you cant connect)

                    Ok on which ip address is the FTP service connected?

                    Can you run the following command on the FTP server and post the output here?
                    Code:
                    Netstat -an | find "21"

                        this is the one where i was interessted in:

                        TCP 0.0.0.0:21 0.0.0.0:0 LISTENING

                        do you have a firewall on the machine?
                        Can you fix the ip address on the FTP service on the internal IP?
