Trouble With FXP Transfers

Postby MTracy » Mon Feb 25, 2013 7:11 pm

I am trying to initiate a transfer between two FTP devices using FXP. The two devices are on the same network, but my computer running FTP Rush is on a different network. The transfer fails without any indication as to why.

If I move FTP Rush to a computer on the same network as the FTP devices, the transfer works just fine, so I assume my problem is related to a firewall or NAT issue?

Any thoughts? I have tried all sorts of different settings with regards to active/passive and the "Server use NAT/Non-routable/Masq IP" option, with no success.

Here is a log from the failed transfer.

You just need to use default settings, if you can't transfer files, maybe the server side does not allow FXP.

Thanks for the response. Both servers allow FXP, and FXP works perfectly if the computer running FTP Rush is on the same network as the FTP servers.

Unfortunately, I need to have FTP Rush initiate the transfer from a computer on a remote network.

I'm having another issue, and thought I'd post it here instead of creating a new thread.

FXP transfers also do not work when FTP Rush is installed on a Windows XP machine. The built-in firewall is blocking it. Disabling the firewall allows the transfers, but that is not something I can do. What exceptions do I need to make in the firewall? I have allowed the program's executable and every port I can think of, but nothing seems to work.

I think I've got it. Using SSL FTP on both servers has fixed both issues.
