ftp server behind router

[hoppa]

I saw a similar question asked a couple other times but I couldn't find an answer.

I'm using Bulletproof FTP with a linksys WRT45G. The server works fine without the router. With the router installed, Ive forward port 2121 (thats the port I use for my FTP) to my local IP. I've also tried DMZ. What happens is that outside people can connect, get prompted for password... they send a LIST request, and don't get it then get disconnected. Here is a log:

So, there's obviously some communication going on here. Why can't it get past this point?

I have always had issues with Bulletproof. I have found that IIS and Serv-U work much better for me.

Passive Mode

Passive mode IP : when you run the server bahind proxy, passive mode reports current local ip (192.168.xxx.yyy for example). To make BPFTP reports correct ip, enter it in the ip box.

* Fixed IP : you are assigned a fixed ip by your ISP, enter it in the box.
* Dynamic IP : you are assigned a dynamic ip and are using a service like dyndns.org (or other) to keep your domain name pointing to your ip, enter the hostname in the edit box.

Passive port range : this is the range of ports that BPFTP Server will use with passive mode, (it is to simplify use of forwarding rule in router for example).
