Thomas, For file transfer the port used is 21 or 20 and for telnet the port used is 23 .. i think .. just check cgain on that part.. you will need to open the file transfewr port on you ISA server to be able to do a file transfer.. also check your publishing rules on the ISA server and confirm if the ISA is not behind a firewall that is blocking access.

I have a customer who has an application that needs to connect thrue a tunneled ssl connection to port 443 to be able to send files. I am able to telnet the sight that the files are meant to be sent to but as soon as i install the application for the filetransfer i am not able to telnet or connect thrue the application. I have checked protocol rules, packet filters ssl bridging and everything looks ok. Any suggestions! ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: syed.muqeem@xxxxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub')
