FTP between remote sites

Some time I need to copy file from one site to another.
To do this, I have to ftp download from one site to local,
then ftp upload from local to another site.
My suggestion is to ftp between the remote sites.
The program already has capability by manual operation.

Those steps need to be done internally
-1. ftp down remote to local temp
-2. ftp up local temp to another remote
-3. remove local temp

You can do that if the 2 sites allows it with a simple drag&drop from 1 site to the other (or right drag&drop for queue with remote sites)

By Drag/Drop I was able to create sub-directory, but no files are copied over to other site. I am receiving "Illegal PORT Command" message.
By Using Q, I get waiting for reply.
Do you have any idea?

It may simply have something to do with one or both of the servers you are attempting to transfer files to/from.

It's never really worked perfectly for me, either, but I never use this feature, so I don't find it a big bother.
