That is what I meant.  I am doing 4 things at the same time.  The important
thing is the difference of where the ports are opened from.  If the clients
are on the inside then basic inspection will take care of opening the ports.
It doesn't have to be mapped to the FTP protocol.  But if clients are
outside the firewall then again inspection is important as with the new ftp
passive option then the proper inbound client connections can be opened.

Hello Tyson,

 

http://slacksite.com/other/ftp.html#passive -> This says the data connection
is opened by the client to a random port ( that the server returns )?

 

Cheers,

TacACK
