Can someone help me explain QoS performance?

with my router connected to the box my connexion seem good but my character in video games is very low

It's working, but there are packet drops. It's normal for cake to drop packets, but generally you want it to drop the right packets, not your game packets. This is part of why cake is general purpose and other scripts I have developed are special purpose for gamers and voip/zoom users etc.

hello dlakelan i'm wait your script finish completly because doesn't work at my home

thanks i'm appreciate your help :slight_smile:

i have a question what the difference between source zone source adress destination zone and detiantion adress

Please go to that thread where we are working on the script and give feedback if it isn't working. I need to know what isn't working to be able to fix it, what is behavior that happens? how do qdisc stats look before and after playing games etc? It won't magically fix itself if I don't know what's wrong!

As for difference between "zone" and "address" the firewall has an idea of zones. They correspond to a set of interfaces: you could have say several LAN ethernet networks all in the same "zone" so they talk to each other no problem, but can't talk to other zones like "WAN" or like "DMZ" or "guest" etc.
