I'm looking for some input on how to set up FTP through an IPFW firewall so that you don't have to run passive mode. Passive mode makes things like building ports difficult. I believe that the problem is that the return connection set up by an FTP server to the client comes from port 20. To open up "any 20" to high port numbers on your system seems like a problem to me. Is there a secure way to do this? -- Jim Durham To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-security" in the body of the message
