Thanks Anthony for the help, but still same problems as before, it will
die before listing the folder with same error.
Also the Secondary Connection 1 & 2 did not work at all, any more
suggestion for this issue, or at least add-on app/utilities/scripts to
solve this?

This is what I did to achieve connections to FTP on ports other than 21
using a Client behind an ISA Firewall.
I created a Protocol Definition for the IP, with the primary connection
set to the Port Number I needed, Protocol Type TCP, and direction
outbound, then for secondary connections I create 2 listings, 1 each for
inbound and outbound, on port range 1024-65535.
Example Protocol Definition to connect to an FTP on port 2323
Protocol Definition Name - FTP - 2323
Primary Connection Port Number = 2323
Primary Connection Protocol = TCP
Primary Connection Direction = Outbound
Secondary Connection 1 Port Range = 1024 - 65535
Secondary Connection 1 Protocol Type TCP
Secondary Connection 1 Direction = Outbound
Secondary Connection 2 Port Range = 1024 - 65535
Secondary Connection 2 Protocol Type TCP
Secondary Connection 2 Direction = Inbound
Then simply adding this Protocol Definition to a Protocol Rule worked
sweetly.
After doing this, I was able to connect to the non standard FTP port,
and use PASV mode for directory listings. (I vaguely remember having
issues with PORT mode)
This only works if the Firewall Client is installed on the client
machine.

Any suggestion for this problems, I connect, but it can not go to the
folder listing for the ftp server, it give "error: time out".
Hi all,
When I try to connect to ftp server that have ports number other than
21, I can not get to the folder list, it will die with "time out" error
msg.
I did protocol definition for tcp/outbound port number, then protocol
rules for that ports, and try with and without PASV, same thing, any
suggestion or recheck I must do, thanks.
