Do I need to have port 20 open for anything related to QWK packet transfers out from my BBS to someone wanting to receive QWK packets from my BBS? I do not see anything on the WIKI about this.
I had originally had my max
concurrent FTP connections set to one, but changed it to 10. What is the usually max settings the rest of you use? I think that was causing some connections a problem. Am I correct. Thanks!

If your users are going to use "passive" FTP, then 2 connections need to made to your system: the control connection (by default on port 21) and the data connection (by default on whatever the control port number is, minus one, so 20 by default).
This is standard for operating any FTP server on the Internet and nothing specialf or Synchronet.
It's up to you, but QWK packet transfers should not be using more than one concurrent connection.

Thank you. I thought so. Should port 20 be set as tcp or udp? Or both in my router?

Correction: TCP port 20 is not used normally or by default for passive FTP data connections.

Thank you. I have passive enabled and I have port 20 forwarded to the BBS,
Re: FTP port 20 and QWK? wait...what?Thank you I will make my correction. I don't want any extra ports open that do not need to be.

Yeah, you don't need to do that. If/when port 20 is used, it'd be the *sourc port from the FTP server back to the FTP client, for data sessions. Since it not used as an incoming port, you don't need to forward it.
