Re: Multiple FTP Servers
A couple of things... * According to https://en.wikipedia.org/wiki/FTPS, port 990 has been "reserved" as the official listener port for the FTPS data connection. * This doesn't mean you must use this port. Our FTPS server uses 8443. Apparently some brainiac thought that FTPS and HTTPS were the same thing... * I imagine you could continue to use port 21 if you want to allow both encrypted and unencrypted FTP. Just guessing here.

Re: Multiple FTP Servers
Yes, absolutely - To listen on two ports you need two FTP server started tasks - Yes, you can have multiple FTP servers on a single TCP stack. Just clone your current FTP config and proc and change the PORT specification. Try that, and then try configuring for TLS (which is more of a chore than is a port change).

Re: Multiple FTP Servers
Hi Roberto, Yes, you can have multiple FTP servers running listening on different ports and only one TCP/IP stack. We are doing this today. We have a unsecure FTP server (that we're actually trying to get rid of) and a FTPS server listening on different ports.

That's true. i'll have to convince security otherwise.

Re: Multiple FTP Servers
Generally, for passive FTP/s, the connection is negotiated on port 21 and then redirected to a higher port.
