   Hello, mark!   
       
    ml> this still needs to be looked into... if passive FTP does not work to a    
    ml> BBBS setup running on any machine with a firewall, then it is a several    
    ml> fold problem... the first being to open the necessary ports... the    
    ml> second, and likely more important, is to be able to configure the range    
    ml> of passive ports used... once the "small" range of ports can be defined    
    ml> for passive FTP, then only those need be opened in the firewall(s) in    
    ml> the path between the system and the WAN... generally speaking, that    
    ml> would be two   
    ml> firewalls... the one on the machine and the one on the perimeter    
    ml> firewall...   
    ml>    
    ml> the key to passive FTP is that the server tells the client what ports    
    ml> to use for the connection... then the client makes a new connection for    
    ml> the transfer using those ports... this is the opposite to "active" FTP    
    ml> in which the server uses the existing connection for one part of the    
    ml> transfer and opens the other port for the actual transfer...   
    ml>    
    ml> in any case, there are OS limitations that must be known and adhered to    
    ml> as well as the software limitations and configuration needs...   
      
   Anyway Mark i dont run the passive FTP anymore just Telnet connection so i   
   have give this up.   
      
   I understand it now what is wrong thanks!
