Block range ip content filtering

Question

EN 
 Hello, I'm new in the world sophos. I installed the free version of Sophos Firewall Home. I tried to configure it to block ranges of IP addresses eg 172.16.16.50-60 and then creating a watch rule on certain category of sites such as pornography, etc., but I see that the rule is completely ignored! If septum rather than a range of a single ip ip rule is successful! What is the proper procedure to do this? thank you.

 Ciao, sono nuovo nel mondo sophos. Ho installato la versione gratuita di Sophos Firewall Home. Ho provato a configurarlo per bloccare dei range di indirizzi ip es 172.16.16.50-60 e creando poi una regola di controllo su determinate categoria di siti es pornografia ecc, ma vedo che la regola viene completamente ignorata! Se setto invece che un range di ip un singolo ip la regola viene eseguita correttamente! Qual'&egrave; la procedura corretta per effettuare questa operazione? grazie.

Hi Mario, 
 Thanks for choosing Sophos. 
 Sophos Firewall has a Top-Bottom approach when traffic is forwarded through the Firewall Rule(s). 
 Check, if the configured Web Filter Firewall Rule is placed on the top of the rest or there is no other duplicate Rule to bypass filtration. 
 You can use the Packet Capture feature in XG to learn, which Rule is forwarding the traffic. 
 To understand Packet Capture, please refer:
