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.

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

<port-numarasır>/<protokol>

- <port-numarası>, RFC-433'de tanımlandığı gibi etkinleştirmek istediğiniz hizmete ilişkin port değeridir (mesela RSYNC hizmeti için 873);

- <protocol>, TCP veya UDP - hizmet tarafından kullanılan internet protokolüdür.

Mesela, RSYNC hizmetine erişimi etkinleştirmek için girilecek değer 873/tcp olur.

Hizmetin her iki protokolü de kullandığı durumlarda, aynı port için iki ayrı girdi oluşturmanız gerekir.
