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 to check whether the port 21 is open or not, it still says that the port is closed. Any idea?
