Hello
I want to open port 21. The firewall in the mac server is already off.The ftp server is enabled in this mac server. The NAT in the router is set accordingly to the internal IP of this MAC computer (OS X Server 10.6). However, whenever I try Online Port Scan | Port Scanning | Port Scanner | Portscan Tool to check whether the port 21 is open or not, it still says that the port is closed.
Any idea?

Thanks a lot

Do you mean port forwarding when you say NAT? Could you explain your router's config?

Not that this solves your problem, but I would suggest enabling SSH rather than FTP so that you can use an SFTP client, as regular FTP is insecure.

yes, i meant port forwarding. The nat settings are so that the 21 tcp communications go to the mac server.

Is port 21 responding locally within your subnet?

Also, is your isp blocking the inbound port?
