interesting discovery.

It would be good for mikrotik to acknowledge and fix

blurrybird

This is still a thing on 7.5.

Pointing the router to an AdguardHome installation with caddy reverse proxy.

Australia is rolling out 1Gbps capable technology to all houses now (and over the next few years). One of the properties I manage is getting it this week, but their hAP ac2 is unable to do 1Gbps routing over IPv6. We need this. (and before you ask, every major CDN can transfer data at 800Mbps+ here.)

blurrybird

hAP ac2 upgraded from 7.2 to 7.4.1 without issue.

blurrybird

IPv6 adoption approaching 40% globally according to Google[1], and 25-30% according to Cloudflare[2] and Akamai[3]. This is arguably higher priority than anything related to ZeroTier / Wireguard, QoS, etc since it is a fundamental part of most networks now. [1] https://www.google.com/intl/en/ipv6/st...

I don't "get" why anyone needs to set a bucket when using cake. Cake has its own shaper.

It's a requirement of the mikrotik QoS interface. Not setting any value here just defaults to a bucket size of 0.1.

blurrybird

lmao ok - definitely cake.

Re-enabling the queue caused my RB5009 to completely lock up until restarted.

blurrybird

Funny you mention the RB5009 - that is what I use on a 1000/50 connection with cake configured and running RouterOS 7.2. Perhaps I'm not loading it up as hard as this other site is loading their 100/40 connection, but I wasn't experiencing instability. I've disabled cake on the rb5009 for now to be ...

blurrybird

Back on topic.. […] I would suggest disabling cake and rebooting for a start, to see if maybe that is interfering somehow? as it is a relatively newer queueing method which has been known to cause some instabilities but my exposure to that is very limited. Thanks for the suggestion here. It is earl...

blurrybird

Router itself shouldn't be locking up from such config , let alone two separate routers with the same error-free config. Are you sure it isn't the WAN connection? Could you try lowering the MTU? I agree, I also tried 7.1.5 with the same symptoms, and I managed to get a teamviewer connection to a PC...

blurrybird

no trace of wireguard

I disabled and deleted my wireguard config (which I was using) while trying to debug this problem.

blurrybird

What have 7.2 for hAP ac2 that 6.48.6 can not do?

cake QoS.

blurrybird

I have a site which I manage remotely over the internet. (INPUT chain has a blanket allow rule from src: my static IP address for simplicity). This site was running a hAP ac2, however the users - heavy gamers - were reporting 20-30 second drops in connectivity. Whenever I tried to connect to the hAP...

blurrybird

hAP ac2 after upgrading was extremely unstable. Would crash and lock up when trying to access it via either webfig or winbox.

Worked out the CPU was running at 400MHz and set to the auto setting.

Setting manually to 716MHz seems to have fixed the problem for now.

blurrybird

CAKE is now happily working with IPv6 again on 7.2rc5 (if anybody was waiting for that). Like blurrybird I am on Aussie Broadband in OZ Mke I'd love to get the following info off you to compare configs: - NBN technology (FTTN or FTTC) - Your speed tier (100/40, 50/20, etc) - Your full queue config e...

blurrybird

Can confirm that IPv6 queues are fixed in this release. Running on an hAP ac2 and RB5009 for some basic home network duties without issue.

blurrybird

Everything is working once again in RouterOS 7.2rc5

blurrybird

When I use wg and allow 0.0.0.0/0 I end up with wg's kernel routes causing havoc.

- Suddenly all traffic goes via the wg tunnel (rather than just site-to-site traffic)
- Suddenly when configuring BGP over the top, routing loops occur.

How have you mitigated that?

blurrybird

RB5009 upgraded from 7.1.3 without issues. Rebooted again to upgrade firmware without issues.

Simple Queues with IPv6 are still broken.

Running this as my home router to see if anything explodes.

blurrybird

The issue reported was not about IPv6 and cake specifically. It was about IPv6 not working when there was a simple queue (of any type) used with an interface as the "target". Cake works fine with IPv6 with queue trees and interface queues even on 7.1.1, but not with simple queues. My unde...

blurrybird

Hey everyone. I'd like to request some help setting up a BGP configuration between three routers that are connected via wireguard tunnels. They're all running RouterOS v7.1.1 stable. Fasttrack is disabled on all three. I am having difficulty understanding the new ROS7 concepts with regards to BGP. S...

blurrybird

I feel compelled :D …but worth reminding that Simple Queues as used in some of the examples in this thread appear to break IPv6 under ROS 7.1.1 (ref https://forum.mikrotik.com/viewtopic.php?t=181705) :( Heh, that's my thread too. Yes it's upsetting, but the Mikrotik Support team said they have repl...

blurrybird

Thank you all for the inputs. I read the original article, and skimmed the updated paper. I've always tried to preach to others that bandwidth doesn't matter; latency does. It's nice to have some solid research on hand to back those claims up. Through incremental (10Mbps) bumps in the bandwidth limi...

blurrybird

Did a bit more testing, you're right. It's working as intended but it's probably still being hardcoded as 'egress' so it's not ideal. Hm, could be related to the test server? I ran two speedtest.net tests at the same time as running a flent test. Code config and attached result below. While individu...

blurrybird

New config with wash disabled created almost an identical graph. I don't know much about the bucket size flag but perhaps this could be my problem? It looks like the mikrotik 'simple queue' incorporates HTB + whatever algo you pick? See this thread I found on the topic: https://forum.mikrotik.com/vi...

blurrybird

My guess is you are thoroughly out of CPU on the download, not being able to crack 400Mbit. What is strange is that the resource monitor in the router would suggest it's perfectly fine doing this (40-60% util on all cores), but the numbers don't lie. You're correct I was going to test on a 100/40 l...

blurrybird

Nice! Now run some flent tests!

Thanks for forcing me to do this - perhaps I'm going back to the drawing board. Cake seems to make my upload nice and consistent, but download and latency is still all over the shop.

Taking suggestions on where to go from here!

blurrybird

RB5009 arrived. Here's some brief testing of cake. ISP: Aussie Broadband Technology: Fibre To The Premise (FTTP) Down/Up: 1000M/50M /queue type add cake-diffserv=besteffort cake-nat=yes kind=cake name=cake-default add cake-ack-filter=filter cake-bandwidth=45.0Mbps cake-diffserv=besteffort cake-nat=y...

blurrybird

You should put cake as interface queue, instead of creating simple queues for it.

You can only assign a single interface queue. How do you handle asymmetric bandwidth limits?

blurrybird

As mentioned in my other thread viewtopic.php?p=901271 and associated SUP-70209 ticket, IPv6 does not seem to be working with any Simple Queues on my WAN interface at the moment.

blurrybird

Seems to be more than just CAKE. fq-codel also affected.

viewtopic.php?p=883027&hilit=ipv6+cake#p883027 seems to detail the same problem.

blurrybird

I've worked out how to raise this via help.mikrotik.com and have created SUP-70209.

blurrybird

Hey all, Seems that when I have a CAKE queue enabled on my WAN interface, IPv6 traffic stops flowing. I have an RB5009 arriving soon, and I'd love to be able to run CAKE-based SQM on my network. Any way to formally raise this as a bug or is that as good as done via this post? Cheers. /queue export c...

I have 100/20 VDSL2.. and this setup has been working like a dream! (The speeds are set to the sync rate in the modem 104/22.. YMMV)

Thanks mate - not a slow reply at all! Mine is syncing 106/41 so I'll throw that in there for now, go for a few days, then see how it is.

blurrybird

Would those with a working CAKE configuration please share their configurations within the mikrotik itself? This thread is amazing, but there are so many dials to tune and so much in-depth discussion going on that someone coming across it for the first time would need to spend hours reading everythi...

@pcunite

Do you have any plans to release an updated 2021 (or 2022) guide for QoS that focuses on RouterOS 7.1.1 and CAKE / FQ_Codel?

I have a 100/40 VDSL connection that could use a reduction in bufferbloat, if you need guinea pigs.

@normis

Any update on this one? I am seeing it with 40 clients.

I am extremely keen to move my DNS back onto the router in a DoH configuration but can't be dropping queries as it was (according to the logs)

blurrybird

Can you give the details on your wifi settings mate?

blurrybird

I'm getting the same thing in my logs. 6.47.4 stable.

blurrybird

@pcunite thanks for doing this. I've noticed a few things that I'd like your input on. 1. I'm trying to work out why you are detecting VoIP by just blanket accepting 10,000+ ports. Often these ports are also used for gaming etc. Is this intentional or by mistake? I'd like to see a variant made where...

blurrybird

Waiting for this and L7 protocol support before I can roll out v6.

blurrybird

Raising this as a feature request for L7 Protocol support within the IPv6 package. This feature is unique to Mikrotik and allows amazing flexibility for SOHO users of the hardware who just want to limit YouTube, Facebook, etc on the network. My current use case of this is a L7 regex to mark connecti...
