Im behind a very strict firewall and have opened up 990 to be able to connect to a host FTP server.
I can connect (the host server sees that I am connected) but I get a error that I cant list folders.
When trying to upload a file I get an error
So, my question is this:
Does WINSCP use one port to connect to the server , and another for actual data transfer?
If so, is it a random port or can it be locked down to say 991?
