Now I could be wrong because it's really hard to determine these problems when the log is edited, ideally if you're concerned about showing the IP address these type of issues should be handled via our contact form.
But from what I can make out the ftp server is returning a local network ip for the PASV reply, it should be returning an Internet IP that can be reached outside of your local network.
Automatic support for handling this situation has been added in v3.6 (the current release is RC3) and you can download it at

As for PORT failing the client computer (the one running FlashFXP) probably doesn't have any rules setup to allow incoming connections, You can define the port range in FlashFXP and then these ports need to be allowed in your firewall.
