Hi,
I am confused about configuring QoS.
I’ve started creating a very simple setup :
| Downlink speed (kbit/sec): | 90000 | |
|---|---|---|
| Uplink speed (kbit/sec): | 90000 |
And
Class: 111
| Interface | Class | Priority | Guaranteed bandwidth | Maximum bandwidth | Burst | Ceil Burst | TOS | Action |
|---|---|---|---|---|---|---|---|---|
| red0 | 111 | 6 | 1 | 500000 | ||||
| undefined | ---- | ---- | ---- | ---- | ---- | ---- | ---- | ---- |
| Remark: | Queueing: | |
|---|---|---|
| Port-Rule: | (tcp) | |
| undefined | ---- | ---- |
| Port-Rule: | (tcp) | Destination Port: 80 |
|---|
| Port-Rule: | (udp) | Destination Port: 443 |
|---|
| Port-Rule: | (udp) | Destination Port: 80 |
|---|
Class: 211
| Interface | Class | Priority | Guaranteed bandwidth | Maximum bandwidth | Burst | Ceil Burst | TOS | Action |
|---|---|---|---|---|---|---|---|---|
| imq0 | 211 | 6 | 1 | 500000 | ||||
| undefined | ---- | ---- | ---- | ---- | ---- | ---- | ---- | ---- |
| Remark: | Queueing: | |
|---|---|---|
| Port-Rule: | (tcp) | Source port: 443 |
| undefined | ---- | ---- |
| Port-Rule: | (tcp) | Source port: 80 |
|---|
| Port-Rule: | (udp) | Source port: 443 |
|---|
| Port-Rule: | (udp) | Source port: 80 |
|---|
(I plan to add other class later)
(also note that the uplink/downlink speed is on purpose way too low for testing purpose)
I activate QoS and do a little speedtest from www.speedtest.net :
Download Mbps
943.85
Upload Mbps
809.07
Which is way above what it should be, as I should be limited to the configured link speed and the class I set up.
Here is the QoS status from ipfire webui :

What am I doing wrong ? Why am not getting speed limited by QoS ?
