ftp many pasv commands?

[Shwick]

I was monitoring some ftp browsing and noticed that for each directory I clicked a new pasv command was sent to the ftp server.

This meant that a new tcp connection was created on a new port every time I requested a directory.

To ensure smooth browsing I have to allow a few new tcp connections per second in iptables.

Is this how the protocol was built, or do I have vsftpd set up wrong?

you might be sets the ftp server with wrong vsftp, or any server problem could be there because you have created new tcp connection with new port. check this and give reply.
