I am having issues getting ports to open on an Airport Extreme. A little background: I am using a Mac Mini Server with Lion Server behind an Airport Extreme. The Airport is fire walled, but the server itself is not. Most server functions (calDAV, Non-SSL IMAP, web server, etc.) are working fine. However, SMTP and any SSL port do not respond. I am trying to open ports to run IMAP, SMTP, and SSLs of both. I have used both Server.app and Airport Utility to open the necessary ports, but when I try to use them outside of the LAN, I'm blocked. Port scanners consistently say the ports are blocked, even though Server.app and Airport Utility both say that port is open. Help?
