Not true.  You simply wait for the port number to be handed to you by 
the passive mode server, then tell the active mode server to connect to 
that port number, with the server's IP address (which the server also 
gives you as part of the transaction process).

The passive mode server provides an IP address and port number to which 
a connection should be made.  The active mode server requests one.  
Just give the active mode server the information obtained from the 
passive mode server.
