Hi, I am fairly new to FTP and am having problems connecting to my home server. I have built a server at home using Windows 2003 and this connects to the internet via a NAT protected router. On the server I have bulletproof ftp server edition set up and most of my family can connect happily using this.
I found your SmartFTP v1.0.980 software recently and only intend to use it for personal use, whilst away from home. Since installing it, I have been experiencing patchy data connection problems which may be down to my NAT protected router. If I bring the server into the DMZ. I can connect without problems. When full protection is restored, your ftp client connects but then falls over when establishing a data port.
The NAT has been set up so that only ports 20 & 21 are open for the FTP connection. When Smart FTP connects, it seems to try other ports for the data transfer and this does not seem right.
This is a copy of the log. I have "*" out all personal data.

I am concerned that the data connection does not use port 20/21 at any time and attempts to use random ports. I assume this is why my router is blocking this, but have been unable to set up SMTP, so that it connects regularly and correctly.
I look forward to any help you can provide.

Simon
