I have a web site that must send published pages to port 32. I have used this
for several years with no problem thru Aug 1, 2007. On Aug 4th I tried to
update the web site using this port 32 but i get an error message #425 Could
not open data connection to port 60084. Operation timed out. I have checked
with itsamac and they say the correct port is 32. They think an update
changed something in Windows XP. Can anyone help me?

It sounds like you're discussion using FTP to publish, as the error message
references a "data connection," which is clearly a reference to the data
connection used by FTP.

FTP actually uses 2 TCP connections, one on the client port (32 in your
case), and another for receiving data (files) from the server. Depending on
whether the FTP is using PASV or PORT commands, the client will either ask
the server for a port number to listen on (PASV) or give the server a port
number to write to (PORT). Most commonly, the client uses PASV, as it
presents less firewall issues on the server. In addition, it sounds like
you're having some firewall issues on the client. Perhaps a firewall is
blocking all but a few necessary ports.

I have found a solution through experimenting. I decided that maybe itsamac
had actually made a change that their tech's did not know about, so i sent it
without the port address of 32 and it went through fine. Their equipment must
now assign the update to any available port as it is received. The problem
was not on my end.
Thanks for your response.
