I have an ISa 2006 server setup with 2 nics. 1 external & 1 internal. All works well except when I publish the FTP server I can login without any issue but always fails listing the directory. The logs on the ISA show it is using other ports for the listing. Those ports are different alomost every time so I do not want to foward them all. The FTP server was working perfectly behind our old sonic wall and nothing has changed on it.
