I installed adam one on Pfsense, until now the filtering and blocking is working fine but suddenly today morning systems with custom filtering policies not getting any sites opened which is allowed for them to open. Once the policy is changed to unfiltered then the systems get connected to the sites. I even tried to stop and start the anmuscle service and gives 1 or 2 min access to the sites and then it break again. Please suggest the solution
Login to your dashboard and open up your current policy. Under “Rules”, check if “Enforce DNS firewalling” is activated. It should be near the top. If it is not activated, turn it on. This rule blocks common methods that attempt to bypass filtering.
We used to have this in place as a forced hidden rule. However, as we had to expand the number of domains in this list some users ran into a need to be able to bypass it, so it was made optional. Since this broader rule could break existing policies we made a decision to send an email about it so users could decide if they wanted to activate it or not.
