FileZilla Server & Client comm issue with LIST command

[dsuess]

First off, we love your product over here at Xeno Innovations for our FTP Server since we switch back to MS Windows as our OS (vs Linux due to compatibility issues). However we're having some problems here with the FileZilla Client & Server talking to each other.

FileZilla Client v3.0.4.1 & v3.0.5.2 cannot connect to FileZilla Server 0.9.25 after the 'LIST' command.. however, if i'm using SmartFTP Client, that works just fine. I checked my settings over and over on bother client & server, i could not find anything. Do you have any suggestions?

Below is a log from the FileZilla Client:

Router or firewall issue, most likely on the server side.
