Having 2 pfsense FWs in a large populated area with 3 VLANs, (students + teachers + admins), I set up limiters in the firewall rules to avoid the connection speed limits to be reached (30Mb up/dwn) This seams to work nicely on tests I've been running on devices of the 3 vlans, for whom I created firewall alliases to. Surprisingly, it still occurs that, as before I set those rules up, I notice wan traffic being on the max of the Internet connection, with no such lan traffic. So, what I am looking for is the reason why the wan traffic differs from the sum of my LANs. The 2 graphs shows both of my FWs, the problem can occur on one like on the other.
Thanks for any ideas.
