I have kids in remote school and keeping them focused is a chore. I use the firewall to block everything and only allow those sites they should be accessing at certain times. I've noticed that they are accessing sites that they shouldn't be able to according to the firewall rules. This is occurring across multiple devices and multiple sites. When I look at the netflow data, sometimes the traffic to a particular domain shows up as 'Blocked' and sometimes as 'OK' and allowed through, seemingly randomly.
The other aspect of this is that when I do allow some sites, sometimes those specific domains that have been allowed by the rule are also blocked.
I've also noticed that I'm not seeing all of the sites that are being visited in the netflow data. The packets are making it through and loading the website on the device, but the netflow information for the domain is completely absent.
Is anyone else having any of these issues? If so, please chime in.
