RNDP4000 Problem with FTP Directory Listing

Hello everyone,

I log in with my FTP client (in this case FileZilla) and everything goes through but it never lists the directory. User name and passwords correct. Port forwarded to RNDP4000 correct. Shares have myself and my group both assigned with read/write permissions. When trying to FTP in from either outside or a computer right next to the box I get the following:
