title: JMeter (Active?) FTP to VLTrader
body: <p>Situation:
  I'm using JMeter to load test my communications application (Cleo VLTrader).  I'm new to JMeter, and have been able to get HTTP communication working, but not FTP.  When I attempt to use a JMeter FTP Request sampler, I can see on the server side that the JMeter is issuing a "PASV" command, and failing shortly thereafter due to a "502 PASV command not available" error.</p>
  
  <p>Question:
  How do I need to configure my JMeter FTP Request sampler to connect to my FTP server?</p>
