I have a FTP7.5 on my Windows 2008 server and would like to use this for FXP, however regardless of the other server in question I can never complete a transfer. It always fails with this message: [L] 501-Server cannot accept argument. [L] Win32 error: The parameter is incorrect. [L] Error details: Client IP on the control channel didn't match the client IP on the data channel. I've tested normal use and it works fine, is there any setting I can change to allow for FXP?
