Durante o monitoramento percebi que o Squid precisava ser reiniciado mais de uma vez ao dia, acrescentei mais dois horários e também alterei o path do cron para utilizar a rotina padrão do Squid. 00 10 * * * root /usr/local/etc/rc.d/squid.sh restart 00 13 * * * root /usr/local/etc/rc.d/squid.sh restart 00 16 * * * root /usr/local/etc/rc.d/squid.sh restart O reinício é rápido e até o momento ninguém reclamou de queda, pelo que tenho percebido afeta somente o acesso a sites, a conferência que era a minha maior preocupação continua funcionando normalmente durante a execução da rotina. O que acho mais estranho é que temos uns 200 dispositivos conectados em nossa rede ( Ethernet e Wi-Fi ) e já ouvi pessoas reclamando do mesmo problema com 1200 dispositivos na rede.

There are many how to's on the youtube and interwebs. Here is one I have saved https://www.youtube.com/watch?v=W2gy1bLHm5o Skip the pfsense install part as it goes through the whole process from pfsense setup to squid, to squidguard, and lightsquid. Squidguard itself is not hard to setup once you have setup you squid transparent proxy which is basically enabling squid, checking transparent proxy, settings caches and that's it for squid then switch to squidguard and configure it. I have squid setup as an HAVP sine it is built into the squid package now and not a separate package before 2.3. Overall there is are many video and guides with pictures to assist in setting up or helping troubleshoot pieces of pfsense you need help with when you google for it such as in your case "pfsense squidguard setup". Don't hesitate you use your Googlefu.
