Have been struggling with this for months and maybe i'm just knee deep and can't see the real problem. But here's the deal, From my ISA server I can login to an FTP site succesfully but whenever i go to do a directory listing or attempt to get a file the Opening ASCII connection prompt open but just sits there and never responds.Now i can repeat the same steps from a machine inside my firewall and it will login and transfer data and directory listings just fine. Which would tell my my proper ports are open. What gives?
