---------------------------------------------

Could you please provide some more detail on this issue. How would I reproduce the issue? Is this for passive or active data connections? What does your configuration contain? 

I've looked at the code and as far as I can see we seem to pick up the session address which should be fine. But I might be missing something :-) I would certainly like FtpServer to work in the type of environment you're referring to so I'll make sure to hunt it down if you can provide some more details.

> The IP used in opening the data channel (DATA command) appears to be determined when the ftp server starts, and never updated again. On systems where the IP address might change (such as any dynamic dns host) this causes all data connections to fail, and requires a full restart of the service whenever the IP address changes (which makes the availability of the ftp server unreliable for practical use).
