I've got a centOS virtual box with GoDaddy. By Default no firewall is enabled.
To the point: I want to set up the regular firewall set up. I however modified the SSH and FTP ports to custom ports rather the default. When I ran system-config-securitylevel-tui I chose FTP, and etc... and saved it. I then looked at the raw config file, and they showed the standard ports for ssh / ftp. So I obviously went ahead and added those two ports to the custom list as: XXXX:tcp, XXXX:tcp, etc...
I don't want to enable it and restart and end up not being able to access the server (locking myself out).
Could someone verify ?
