You say that the error is a timeout? When does the timeout occur?
Does it occur on the initial connection, or does it occur when trying to
perform a transfer (i.e. a PUT, GET or directory listing).

On the initial connection.

On the other hand, if it's happening immediately during the initial
connection, then it's a simple TCP connection to port 21 that's being
blocked by a firewall.

Here's the log from a Telnet session

jon-paris-computer:~ jonparis$ telnet frankieiii.frankenseries.com 21
Trying 65.183.178.117...
telnet: connect to address 65.183.178.117: Operation timed out
telnet: Unable to connect to remote host

jon-paris-computer:~ jonparis$ telnet partner400.com 21
Trying 63.167.147.110...
Connected to partner400.com.

So I can telnet to one system but not the other. I also verified that the same scenario applies with FileZilla just in case it was misinterpreting a response.

So it would appear from this test that any firewall issue must be on the 400 side. But if that is the case then why is it that I can connect via 5250 to another completely different 400 and then happily telnet to the problem system that failed above! Doesn't that indicate that there is no firewall blocking port 21 on the box?

Since it is a straight timeout is there any point in doing a comms trace?
