How can i set up the peplink balance 30 to capture web activity to syslog?

i have a local syslog server and it captures all pepvpn and power activity - but it doesn’t capture web activity from the local clients - or at least i cannot get it configured to show up in the syslog. any ideas?

Model:

Peplink Balance 30

Firmware:

6.1.2 build 2717

Please upgrade your firmware to 6.3.1 and then you will see a Content Blocking tab under the Firewall heading. Here you can enable URL logging and send to your syslog server. Thanks.
