    FTP Passive mode ports


    Can you tell me what are the inbound and outbound ports when FTP Passive mode is used for PureFTPd.

    Thank you.

    There are no "defined" PASSIVE ports (to my knowledge) but I've been using the following ports under PureFTPD for several years without any issues:

    PassivePortRange 60000 65500

    That will basically allow the FTP daemon and client to open a port between 60000 and 65500 which should be more than enough for even a busy FTP server. Also, if you have a firewall don't forget to open the port range or they will not work.

    I believe that RFC 959 just mentions a high numbered port, which would be 1025-65535 for both ends of the data connection.
