I have a network that is completely virtualized using Hyper V. I have virtual machine that I setup FTP services on. Everything is behind a Cisco ASA 5505. Internally the FTP site works as intended. I put the IP into IE and am able to logon and get a directory listing. Externally however is another story. When I enter ftp://external
IP into my browser I am prompted to logon but no matter what I get the following error:
"An error has occurred opening that folder on the ftp server. Make sure you have permission to access that folder"
200 Type set to A.
227 Entering Passive Mode.
I am assuming I have something missing on the ASA.
