QoS - Is the traffic really prioritized or is it just guaranteed bandwidth?

Hello UTMaddict ,

Thank you for reaching out to the community, Under the Interface & Routing > Quality of Service (QoS) > Traffic Selectors > Add New Traffic selector. Here you you can define how this traffic gets handled by QoS, like limiting the overall bandwidth or guarantee a certain amount of minimum bandwidth Where as under the bandwidth pools you can define and manage bandwidth pools for bandwidth management, with a bandwidth pool, you reserve a guaranteed bandwidth for a specific outgoing traffic type, optionally limited by a maximum bandwidth limit. So I would not say it as traffic prioritizing but guaranteed bandwidth. Hope this clears your doubt.

This means the UTM can't prioritize the traffic. It can only guarantee bandwidth?

In conclusion: It's not a full QoS. Something like QoS lite.

Hey UTMaddict You can say that, as features like prioritizing, Latency, Jitter and Packet loss are lacking but you can migrate to Sophos Firewall which fulfills all the criteria mentioned.
