USG Flex 500 Content Filtering does not work

Hi @Scott_Gorman @GiangiSkan,

You can use DNS Content Filter to block social networking.

In Security Service > Content Filter > DNS Content Filter, click the profile BPP and select "Social Networking".

Apply the DNS Content Filter profile "BPP" to both security policy rules.

• From LAN1 to any
• From LAN1 to ZyWALL

The website of facebook can be blocked by DNS Content Filter.
