The following section describes yet another frontend: `system-config-firewall`.

The GUI interface is similar to the text based interface just more friendly.
|
|
|
|
|
|
|
|
The first time you start the GUI you will receive a warning. The program will
|
|
|
|
*not* load your custom configuration. So any preexisting rules will be
|
|
|
|
overwritten.
|

|
|
|
|
|
|
|
|
Before you start, you have to enable your firewall to activate the
|
|
|
|
configuration utility.

The initial configuration is empty and will not allow any network traffic.

|
|
|

|
|
|
|
You can ignore the warning and start the wizard. Click _forward_:

|
screen,title="Firewall Wizard : welcome screen"]
|
|
|
|
|
|
|
|
Choose _System with network access_ to enable the firewall. The other option
|
|
|
|
_System without network access_ would disable the firewall and don't allow
|
|
|
|
access to any network.

|
|
|
|
|
|
|
|
Next, you have to choose your skill level. The *Beginner* options only
|
|
|
|
allows the configuration of _trusted services_. This option is fine if you only
|
|
|
|
want to use services like _ftp_, _dns_, _http_, etc. It does not allow you to
|
|
|
|
configure customs port ranges. If you select *Expert*, you will have access to
|
|
|
|
firewall options. You can change the skill level later via _Options_ in the
|
|
|
|
main window.

|
You can choose from a set of default configurations to start with. The *Server*
|
|
|
|
template will only enable SSH on the firewall. The _desktop template_ enables
|
|
|
|
additional ports (_IPsec_, _multicast DNS_, _Network Printing Client_ and
|
|
|
|
_SSH_). For convenience select *Desktop* and continue:

|
|
|
|
|
|
|
|
To enable additional _trusted services_ just choose the services from the list.

|
|
|
|
|
|
|
|
You can add custom rules after choosing *Other ports* from the side bar. Click
|
|
|
|
the *Add* button and either choose form services list on the right or tick
|
|
|
|
*User Defined* and fill in the requested information.

|
|
The other options in the sidebar *Trusted Interfaces*, *Masquerading*, *Port
|
|
|
|
Forwarding* and so on work exactly as in the text based interface.
|
|
|
|
|
|
|
|
When you finished the configuration, click *Apply* to save and activate the

firewall.
