Dear Bogdan, I am not very familiar with ISA, but I think this problem maybe your incorrect FTP Server Protocol Definition. To allow the FTP Server work under passive mode, in other words it should allow clients to establish a subconnection to the server. You shoould not use the default protocol defined by MS, because it is not listening to incoming subconnection request. This is only my supposition. Maybe it will not work at all.

Another company UPLINK the Internet to satelite. I'm joust the manager and owner to this service. (europe) At out headquarter in Ro I have a ISA server. When my cusstomers try to acces some FTP sites trought this isa (who have a VPN with satelite UP LINK STATION) they got an ext3ended error messages. ISA Server: extended error message : 200 Type okay. 200 PORT command successful. 550 Cannot connect to 62.41.25.3:35457 - Connection refused. This is becuase the UPLINK platform are setup to work in PASIVE MODE when handle the FTP. So I have few choice - setup ISA to work in PASIVE MODE when handle the FTP acces - setup entire platfirm to work in ACTIVE MODE (it is a little bit harder) - drop the business and go to mointanis for meditation and pray :) Please look very carefully and advice me beucase it pass more than 3 months I try to find a solution for this.
