RE: Unable to FTP to i from desktop

Try using Passive mode. Also make sure your firewall has port fix up
set for FTP. And yes you will need to open a second port for FTP,
usually 20. You see port 21 is the command port and then the client and
server will negotiate a second connection for data transfer. In passive
mode, the server sends the IP address and port number to the client for
the data connection so the client can initiate the connection. In
standard mode the server attempts to connect to the client on the IP
address the client used for the connection and port 20. That does not
work if the client is behind a firewall.

Subject: Unable to FTP to i from desktop

Hi All,

On Friday, I was a bit premature in thinking my problems with FTP was
solved.

I am trying to FTP from my dsktop to the i, using the live address
65.xxx.xx.xxx. I opened up port 21 on the i, with NAT to 192.168.100.7
(local address of my i). So I get prompt for user id, then password and
on
entering both get a message saying I am logged on. Then if I give a
command
to change my current directory, that too works fine. But when I try to
access any data, even a simple "dir" command, after telling me "PORT
command
successful", the PC goes into a wait mode for about 5-7 minutes and then
comes back with an error message "Not able to open data connection". At
about the same time, on the i I get a message saying TCP/IP connection
closed reason code 2. I think the data port for FTP is 20, so I have
that
open too, with the same NAT as port 21.

Any ideas?
TIA
