Packet loss

I’ve been experiencing a lot of packet loss for some time now, I thought it would correct itself eventually, however, it’s been over week and it’s still the same. See the attached screenshots from zabbix, I’ve also attached icmp response and loss from google dns as well. The red around 21:00 is probably when I rebooted the firewall.

This is google dns

Best would be to run tracert, traceroute or (Win)MTR. These graphs are useless when it comes to network troubleshooting.
