client disconnects after uploading with fxp

[Eddy]

Hi guys,

Background Info:
Windows XP SP1
Bulletproof ftp server 2.15
behind router

First the server didnt worked so i opened port 21 at the router settings for the PC (10.0.0.9) where the server is running on.

People can acces my server, see the files, download and upload. but when someone (user C) tries to get another server (b)connected to my server (a) with FXP (http://www.bpftpserver.com/?page=faq&lang=en#Connection,internet.13)
it disconnects... this is what the server log says:

so it just hang and disconnects... :(

the client already changed the passive mode so it cant be that i think.
i have unselected the "block server to server transfer" so it cant be that either


Can someone help me with this?

Do i have to open more ports? (i have only opened port 20 and 21 so far, both tcp)
Or does it got something to do with the (passive) port range? and is that in the ftp server configuration or is that in the router.. or both maybe?

i hope some1 can help :cool:

Maybe the server doesnt allow fxp? I personally dont allow server to server so I've never gotten into troubleshooting it

[Eddy]

what do you mean with not allowed?

i have unselected the box for "server to server transfer (fxp)" so that should be ok i guess

you think it hastnt got anything to do with the ports?

ill try to put mt computer (where the server is at) into DMZ and then see what happens.... ill tell u when im ready

[Mntsnow]

Well I will say that either the client or the server is wanting to use pasv mode as it shows that it was communicating for pasv, as shown in the snippet you list above.

Both server and client need to be configured to use pasv or both need to be configured to not.

[Eddy]

So you do think it got something to with the passive mode?

ill try it and get back to you ASAP!

[Eddy]

Hod do i put the server to PASS or not PASS?

[Mntsnow]

Are you wanting to use passive mode or not? If you want to use passive mode you will need to open up alot more ports on your firewall to have it work.

[Eddy]

If it makes my server accesible after that i will give itt a try!

But i wasnt realy able to find out what these modes means or what ports to open for them
