Can anyone offer some insight to this...
I have a FTP server sitting behind my ISA on a DMZ. I need my internal user(s) to transfer files to the FTP server. I have set my IP filter rule as follows:
Inbound Connection
IP protocol: TCP
Direction: Both
Local Port: Fixed
Local Port number: 21
Remote Port: All Ports
Outbound Connection
IP protocol: TCP
Direction: Both
Local Port: Fixed
Local Port number: 20
Remote port: All Ports
I have allowed this communication to take place from the internal network. Users from the outside can not get in.
Problem:
I get data transfer to the FTP server through the ISA server, but at times the connection or file transfer hangs up. At times I can not even connect to the FTP server because my connection is refused by the host (I assume the ISA server). Why is this happening? Could there be another rule in conflict? Timeout? etc.
