We want to set up queue tree to give voice packets priority over other traffic,
Router is sxt, our local interface is ether1, and WAN is wlan1.

Configuration is not working and we will appreciate any help.

ip firewall mangle print

@Philomena

Hi, could you solve the problem? I'm having the same issue here, don't know what else to do, I'm freaked out. Thanks.

Did you turn off fast path in IP settings?

Actually I don't know. I'm gonna check and let you know.

Did you turn off fast path in IP settings?

I tried turning off fast path but same problem, as an example, here is my config:

0 ;;; ICMP Packets
chain=prerouting action=mark-connection new-connection-mark=Services_P1_Conn_Upload passthrough=yes protocol=icmp icmp-options=8:0-255 log=no
log-prefix=""

log-prefix=""

2 chain=postrouting action=mark-connection new-connection-mark=Services_P1_Conn_Download passthrough=yes protocol=icmp icmp-options=0:0-255
log=no log-prefix=""

3 chain=postrouting action=mark-packet new-packet-mark=Services_P1_Traffic_Download passthrough=no connection-mark=Services_P1_Conn_Download

Actually, when I tried to ping when the connection is overloaded, the ping doesn't take priority 1, the time in ms are higher than when the connections is with a normal use.

board-name: RB951Ui-2HnD
version: 6.34.1 (stable)
additional info: SOHO default configuration by MikroTik (dhcp, default filters, etc)

What I would like to do is to give priority to specific traffic, but doesn't work very well. Any advice?

It is too difficult to debug someone else's problem with just a snippet of the config, but I can assure you that
the queue tree works well here. But fast path needs to be off.

Just fasttrack-connection all voip connections, and problem solved. (you will need to enable ip fastpath back )

Hi all, thanks for taking your time, just to avoid reading the config, the algorithm is like this:

Ip firewall mangle
1- mark Icmp prerouting connections, pass-through =yes
2- mark packets of above icmp prerouting connection pass-through =no
3- mark Icmp postrouting connections pass-through =yes
4- mark packets of above rule pass-through =no

Queue tree
1-Parent upload and download created with just max limit setted to 90% of connection
2- create other queues with upload and download as parents and use the marks I setted up in mangle and give its priorities.

Problem
1- I tried to give priority 1 to icmp and give it a limit at and max limit options (I have tried almost every possible combination of limit at and max limit) and seems that that priority doesn't work as I expect, why? Because when the connections is not overloades the ping takes like 68ms the reach an Ip on the Internet, but when the bandwidht is reaching the max limit the ping starts to increment the time from 68ms to 159ms or more (250ms and more)

What I want?
Give icmp (or other protocols a real priority against the rest of traffic.

Thanks, I hope someone can help me.

PD. Haven't tried fast tracking very well, I'm gonna test it.

PD2. Disabling just fast path didn't work, but anyway I'm gonna try some other possible configs with fast path enabled.
