FXP outgoing problem with Win2003

[Jog]

Hi guys,
i've a site with latest ioFTPD and i've some problems when i make FXP outgoing to other sites.

This is a Win2003 machine, the others are WinXP or Win2k.

the configuration of my ioFTPD is the same of all other sites, but with this one i had a problem when making outgoing FXP.

It transfer one file and so it blocks, i had to disconnect from ftp and relaunch my queue, so it transfer An other one file and it blocks ... and so on!
I tryed 3 different clients (UltraFXP, FlashFXP and FTPRush) but always the same problem.

My scripts are: ioA, php_psio, NewDir and others not relevant, all at the latest version.

Any idea?
The only difference between this and others site is that here i have Win2003 :(

I doubt there is a problem with ioFTPD and Win2k3. It's developed on machine running Win2k3 so.. Must be something in your config or problem with hw, fw, nic drivers or something.

What port settings etc. do you use?

Try to fxp to another site.
This might be a problem with the remote site you're sending to.

Had same problem when testing/configuring my own FTP and after a while I found out that it's a "different" problem and has nothing to do with which OS you are using or ioFTPD or any other FTPD.

You're behind a router on a LAN trying to FXP out from that same LAN to an outside FTP. You connect to the internal (LAN) IP of the FTPD from an internal (LAN) IP then trying to fxp from there to a WAN IP. Simple test is to let "outside" users try to do same and you iwll see it will fxp out, simply cuz they connect to the EXTERNAL IP and router doesn't have problems with that (that is when you set up the correct pasv range in your router and ini ioFTPD file).

There probably is someone aroudn here wjo could give a more technical correct explanation but this is the "done by a common user" one ;)

One more remark if the above explanation is true....:
Why fxp from your lLAN to another ftp when you have same or even faster results (not as much resources. in between steps) uploading from your harddisks to outside FTP?
