Multi VPS Server Setup FTP Login Problems

Debian Squeeze, Apache, ISPConfig 3.0.4.6

I followed the guide here: http://www.howtoforge.com/virtual-m...ns-servers-on-debian-squeeze-with-ispconfig-3 except that I said yes to install the firewall in the ISPConfig install.

I created a FTP user in the control panel and am attempting to connect with FileZilla, but I keep getting this error in FileZilla

Any ideas why the connection gets timed out?
