Cannot list directories

I'm having a pretty frustrating time trying to access my dedicated server with Bulletproof FTP server installed via Flash FXP.

I can connect to this sever in my work using Flash FXP but when i try from home i cannot get the directories listed. Log is below.

Hello,

Does the site IP that you have marked out match the PASV reply that is also marked out?

You marked out the one part that we need, specifically whether or not they match.

Yes they match, they are the same live IP address of the server...

Many thanks,

S

Here is the full details...I have opened 21 and 20 on the server firewall...

Looks like that server is misconfigured for PASV mode by not having all the proper ports opened. Port 20 and 21 is not enough. Read this article for explanation of how ftp protocol works and what ports are in use http://slacksite.com/other/ftp.html

Thanks for the link...what I don't understand is why I can connect from my work without any issues...very strange.

I have tried opening all ports on the server and disabling my own firewall and still i cannot get a directory listing...this is driving me insane...could this be connected to any VPN software on my laptop?

S

I have now tried a rule for Any IP to come in on Port 21 to ANY local port on the server and still the same problem...

S

Ok now i have removed VPN and all anti virus and disabled firewall on my client/laptop.

Still no directory listing.

I would like to download an older version of FLash FXP, where can i get version 3.6?

S

The FTP server needs to allow incoming connections to ports 30000 and above? I'm not sure the entire range used by BulletProof FTP server but it looks like the range starts around around 30000.

These ports need to be open on the server for the FTP client to connect using PASV mode.

You mentioned that you opened all the ports on the server, that should of been enough to make it work.

It is unlikely that your VPN software is a factor.

I would recommend removing the firewall rules you added to your local machine for FlashFXP and then add them back. You might need to reboot after removing the rules, depending on the firewall and operating system.

You can download FlashFXP 3.6 using this link , however v3.6 is not 100% compatible with Windows Vista or Windows 7 and should not be used on these versions of Windows.
