Exclude guest network from fasttrack to limit its bandwidth with simple queue - possible?

RouterOS General

Hello.
I just spent some time digging why simple queues doesn’t work and then I found that fasttrack doesn’t come along with them. Actually I didn’t have idea what fasttrack is so I read some stuff and I liked it. However I would also like to have my guest wifi limited to 5MB. Guest pool network is 192.168.100.0/24. I though’t of something like that, but looks like it doesn’t work. Any idea why?

Add accept rules for guest subnet before fasttrack rule

Switched places 7 with 8 and now it works. Is that good way too? Or should I copy this allow rule and for guest network place it above fasttrack and for rest leave it under fasttrack as it was?

With the above setup the fasttrack is “disabled” as it never applies. You’ll need your second suggestion:

  1. accept not to be fast-tracked traffic
  2. fasttrack
  3. accept for faststrack

Thank You. It didn’t work at beginning when I applied network IP in allow rule same as in fasttrack but without “!”, but when I used whole guest bridge it works.

But as I am very curious person one more thing did cross my mind. If the guest-accept rule is now above fasttrack, then it should catch traffic before it reaches fasttrack right? So I could remove that !192.168.100/0/24 from fasttrack rule. But when I do that it just passes the allow rule above and goes at full speed again. Why is that?

It is possible that the confusion has arisen because the

accept=established,related,untracked

works with long term connections,
so when you make changes you need to wait for existing connections to end, or else remove them (which will cause a storm of invalid packets…)

You can watch the existing connections with

/ipv6 firewall connections print where src-address~"^192.168.100" or dst-address~"^192.168.100"
