Firewall

This section allows you to + configure some simple firewall rules: they determine which type of message + from the Internet will be accepted by the target system. This, in turn, + allows the corresponding services on the system to be accessible from the + Internet.

In the default setting (no button is checked), no service of the + system is accessible from the network. The Everything (no + firewall) option enables access to all services of the machine - + an option that does not make much sense in the context of the installer + since it would create a totally unprotected system. Its veritable use is in + the context of the Mageia Control Center (which uses the same GUI layout) + for temporarily disabling the entire set of firewall rules for testing and + debugging purposes.

All other options are more or less self-explanatory. As an example, + you will enable the CUPS server if you want printers on your machine to be + accessible from the network.

Advanced

The Advanced option opens a window where you can + enable a series of services by typing a list of “couples” + (blank separated)

<port-number>/<protocol>

- <port-number> is the value of the + port assigned to the service you want to enable (e.g. 873 for the RSYNC + service) as defined in RFC-433;

- <protocol> is one of + TCP or UDP - the internet + protocol that is used by the service.

For instance, the entry for enabling access to the RSYNC service + therefore is 873/tcp.

In case a service is implemented to use both protocols, you specify 2 + couples for the same port.
