Hey Zoltan, check here for the port numbers http://www.isaserver.org/cgi-bin/ultimatebb.cgi?ubb=get_topic;f=2;t=003672 Port Number: 21 Prot Type: TCP Direction: Inbound Secondary conections: 1117-5190 TCP Inbound 41000-50000 TCP Inbound And here is configuration information. http://www.isaserver.org/cgi-bin/ultimatebb.cgi?ubb=get_topic;f=2;t=003417 Note that Audiogalaxy uses port 21 for file transfers and you will have to disable the FTP application filter. This will break the FTP protocol. hope that helps. -----Original Message----- From: Zoltan Batky [mailto:batky@xxxxxxxxx] Sent: Tuesday, April 02, 2002 8:10 AM To: [ISAserver.org Discussion List] Subject: [isalist] AUDIOGALAXY through ISA Server http://www.ISAserver.org Please, help, if you know, how... I would like to run Audiogalaxy on my PC, and I connect to the web through ISA Server. How can I open ports for it (it needs port 21 and some 4xxx)? Do I have to do it through the server console, or from my PC, or... Thanks in advance!
