Based on your log I suspect your internet connection uses NAT (Network Address Translations).

In most cases you can not FXP with NAT. NAT provides a transparent protocol handler which insures the right IP is sent to the ftp server for PORT commands, however in doing so it breaks FXP. Most NAT designs will only monitor port 21 for the ftp protocol. So if the ftp server was on say port 2121 it would not be effected by NAT.

There are some previous theads where NAT was discussed and several users have made their own suggestions. Perhaps you should try searching the message board.

It seems I figured out the problem. It should be related to the location of FlashFXP client running.

I have tried FlashFXP at home with single broadband connection which transfered files from FTP Site(A) to Site(B), it is no problem occurred. However when I tried to do it gain in office which is under LAN connection, it failed as per the above log.

Therefore, I believe the location of FlashFXP client runing is relevant to the above problem.

My office uses broadband IP sharer. I have tried to host a server in the past but failed as I learned that I need to amend the setting in the sharer related to IP issue.

Please advise.

A piece of hardware used at your office is using NAT more than likely it's the broadband IP sharer.
