Hi, I have tried to open for uploading files with ftp to a website, secondly tried to communicate with skolekom.dk with the FirstClass client (port 510) via the ISA server but sofar without luck. I have tried to open all ports for all ip trafic etc, but again no luck. The funny thing is, i have tried doing the same at my own place without having any trouble (with the same configuration), so i don't understand. Do you ?? Please help /Jens
