In need of help with FTP connection problems

    I have set up an Ubuntu Server with ISPConfig following various Howtos and hints from this forum. The server is up and running, and ISPConfig reports no problems for more than three days now, serving the default pages on the domains pointing to the machine. So far, so good. Now I want to start to actually put content online, for that purpose I've created a reseller, a client and a website for that client. That website's default index.html is online, so that is fine.

    The server is a VM with a fixed IP, and my DSL-router is forwarding both port 20 and 21 to the VM. There is no firewall running on the server VM. (ISPConfig shows it as off in Management). If I connect to the local IP using FileZilla with the login credentials of the user created for the website (web3_blahblah, this is the admin user for the website), I can get to the directory listing and even browse through the various directories. I can not, however upload or download a single file.
    All I end up with are files with correct filename and 0 bytes of size on the server. Downloads result in nothing at all. FileZilla will ask me whether to overwrite or replace the existing 0 byte file when I try to copy files again, but the upload fails again immediately.

    Trying to connect from the internet (from a remote windows server i connect to via RDP, also using FileZilla) I don't even get to the directory listing.

    I have not touched any settings for ProFTPd. My installation procedure was as follows:
    Code:
    apt-get install proftpd proftpd-common ucf
    
    I chose to run proftpd to run as standalone.

    Then I added the two following lines to proftpd.conf
    Code:
    IdentLookups off
    ServerIdent on "FTP Server ready."
    
    Where do I go from here? What settings can I check? Any help would be greatly appreciated!

    Some additional information:

    I've now added the following line to /etc/proftpd.conf:

    Code:
    PassivePorts 34000 34100
    
    and restarted proftpd.conf.

    I have forwarded the above port range (TCP only, no UDP) to the VM's local IP in my router's settings.
    Then I specifically set the transfer settings in FIleZilla to passive mode.
    Still no go, the symptoms haven't changed at all.

    Any hints?

    Have you tried active mode as well?

    Are there any errors in your log files?
    What's the output of
    Code:
    netstat -tap
    ?

    Sorry for the late reply, but this is the output of netstat -tap:

    What logfiles would I best look into?
