this could be a problem related to how FTP works in general. I assume clients can connect, but then not download? Well you need also FTP-DATA (TCP 20) which is used for downloading natted to your server.
This still leaves you with clients not able to download in case they are set to use passive FTP. In this case download will be client initiated to an arbitrary TCP port your 1841 has not NAT translation for.
Generally FTP Server and client being behind NAT does not work in most cases. Have a look at RFC 1579 Firewall Friendly FTP for a detailed explanation.
Basically you need an official IP address for an FTP server or an application aware Firewall/NAT to have no hassle.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
