-                       IPFire ist mit einer SPI-Firewall (stateful inspection) ausgestattet, die auf dem

-               </p>
-               <p>
-                       Jede IPFire-Installation teilt das Netzwerk in kleinere, voneinander getrennte Teile,

-                               explizit zugelassen werden, um auf das Internet zugreifen zu dürfen.

-                       <li style="color: red;">

-                       <li style="color: orange;">

-                       can also control outbound Internet access from any segment. This gives the administrator
