Wao my latency changed from 34 to 6 you are the best for doing all these videos to help the community.

Simple to follow. My latency went from +97 to +2. I may or may not play with up/down speeds but I doubt I will notice the difference. More importantly, I would never have found out about this pfsense optimization had it not been for another excellent Tom Lawrence video tutorial! THANK YOU.

Went from F with +544ms down / +100ms up, to an A+ with 1ms up/down on a fiber connection. Crazy! Thanks so much!

Tommy is the best when it comes to Network optimization and explanation.

Wow - was not aware of this issue (not a gamer). Implemented and went from a "B" grade with 45ms to "A+" with 1ms. Thank you!

Took me from A to A+ on my 920/110 line ... I do quite a bit of gaming so ideal for me. Thanks Tom!

I thought I already had this set up. Noticed some differences between your (the Netgate documented) method and what I had done, made the changes and it took me from an A to an A+. Thank you

What a great video! I've implemented something similar with my Mikrotik router, and there are no more lags in the games. Thank you for sharing your knowledge with us.

Went from C to A. Thanks!

Nice video! I would have been really interested in a brief explainer on what each setting does and why the given option was chosen (e.g. FQ_CODEL). I'm glad this brought bufferbloat to my attention, and I'd love a video going a bit more depth into what's going on.

I didn't think that this would be much of an issue for me since my dedicated firewall miniPC is relatively powerful. Went from a D (?!) to an A! Thanks for your great video and advice, Tom - as always! 👍👍

Thank you for this! My Idle, Download and Upload latency went from 4/27/57 to 4/4/4.

From C to A, awesome. I play games a tonne and am now noticing general responsiveness improvements too. Should of done this ages ago.

Very nice, Worked very well. Love it!!

Pretty good response on my setup aswell! Thanks Tom

Thank you for this video! I learned a new thing and improved my network! You're a legend! More videos like this, if you don't mind!

what kinda sucks is that its really cumbersome to test various parts of each option - for example if you go for traffic shapers rather than limiters, some of them can add significant cpu overhead (FQ_CODEL as a limiter doesn't seem to do this). I'd love a video where someone actually tested the various overheads. also a lot of these videos focus exclusively on LAN/WAN connections (which most people have) but quite a few people run VPNs on the router now, and some even have all traffic running through VPNs. I've set up mine accordingly but it would also be nice to have a video focusing on those different kinds of configs. Some people run very high bandwidth applications too, which saturate networks (tor clients, torrent clients, open directory web servers / file servers) so it would be nice to have a best practice on how to ensure proper limiting of those (i did this through using the weights system and it seems to be working but i dont know if this is correct)

hah so strange I just checked the documentation for that just yesterday! great timing, thanks!

Needed this few months ago when Wide Open West forgot how to manage their network. Followed an older tutorial that helped some, but issue was WOWs end in the end. Best I could get was a C grade after limiting

You are a networking wizard!

Thank you for this.

Always top quality content, thank you sir! 👍

Thanks for another great tip Tom, you're the best!

C to an A for me as well, even on my lowly 50mbps business class circuit.

Oh, so its basically what QOS settings do on other routers. Keeps your internet speed down JUST A BIT, so theres a little free bandwith for High priority things to jump through the Q instantly. Need to get this setup asap Thanks

Thanks for raising the issue! Having the consumer set up the limiter on their end is a sign of an ISP "cheaping out" - at least in my part of the world (Germany). My experience ranges form very well implemented (Telekom) to nothing at all (Vodafone Kabel - here a FW capable of setting up limiters was pretty much mandatory; at least in the past)

I just couldn’t get this to work it just shut me out off it all but good video

Thanks!

My Buffer bloat grade changed from an F to A+ and the latency changed from 63ms to 4ms download to 494ms to 5ms upload.

Watch out for trash bytes in config files creating and deleting limiters. Same with changing unbound repeatedly. Sometimes you gotta manually fix things if you fiddle with settings too much. Never delete an interface without deleting firewall rules first. Trash leftover firewall rule bytes. If you use the layer 2 firewall be sure to have all your rules memorized. Lots of floating rules and layer 2 rule creation and deletion causes all of the rules to get mixed up randomly, and eventually I found it best to put my limiters and layer2 rules on non-quick rules. Last match rules and aliases are amazing. pfSense's rules are so awesome though 😅 If you can code your own firewall though, you are golden.

If you attempt to do this on with a IPv6 WAN address. The source in the floating rule can't be "WAN-address" because you probably don't NAT with IPv6, use "any" instead or if you have a fixed prefix, use that. (no I did not just spend 4 hours thinking my Pfsense was borked. What do you mean?)

Tom, as always, you and your videos are blessings for us novice IT adventurers. Thank you. I'm curious though, several of my more mobile devices use Wireguard to "phone home" when out and about. Would one need to make any accommodations for that when running the initial Bufferbloat test and/or setting up the CoDel Limiters? Running the Bufferbloat test with Wireguard activated on my laptop (connected via LAN) was almost 600 mb/s. Without Wireguard activated, my "gigabit" internet went back up to its usual 936 mg/s or so.

Big disclaimer for those on connections with unpredictable speeds!! My internet upload can vary between 35 and 50 mbps. I've tried every possible "buffer bloat" fix under the sun and nothing works if you can't set limits under which your speeds will not drop... Cable internet is a "shared medium" amongst everyone in your neighbourhood.

Started with A and ended with A followed details to a T. Dedicated 500/500 fiber

380ms to 1 ms is a wild difference

Interesting, after playing with the settings for a while I found it did absolutely nothing for my download at +40. But it significantly changed up upload from +50 to +3.

This test was interesting. I have 2G/2G Internet. My devices on a 10G connection get A with latency 16/7/1 and down/up 2100/1900. My 1G test devices were C with latency 25/34/162 and down/up 529/924.

Have you reviewed the netnuma r3 gaming router?

I was literally about to start a thread with netgate about this. 😂

Not sure where I've gone wrong but my 1G fiber went from a C with 19 ms unloaded, +8 ms download, and +61 ms upload to a C with 17 ms unloaded, +8 ms download, and +154 ms upload. I'll have to spend some time testing different upload and download bandwidth values and see if I can improve things.

With NordVPN installed on a Netgate 1100, I get a D or F, latency of over 300 ms down, 200 up. With the VPN turned off, I get an A, latency is much lower. I may have to forget about using a VPN now.

Ran the test and got a B+...so naturally now I am wondering how/if I can do something like this in Unifi? I just got into Unifi two weeks ago, so I am still learning.

Thank you for a great tutorial and raising awareness of this issue. However, I think it might have been good to mention that in order to make this fully work in a IPv6 enabled environment, a second floating rule must be made for IPv6 (and not set the protocol family as IPv4+IPv6). As per the pfSense guide.

Can you make a video on what gateways we should add the rules or on what it makes sense? E.g vpn client gateway?

This is pretty cool. I have redundant WAN connection with two ISPs both with different bandwidth. I presume I would just created each one individually and assign it to each individual WAN interface even though they are in a gateway group? Or would I have to use the lowest common denominator and apply it to the gateway group.

Quick question: How (or do) you alter this with dual/multiwan, with our without a gateway group? I just went through and did this on both WAN connections.

My connection is 1000/50, originally my download latency was +45-55ms. After going through this tutorial and i am getting +200ms on the download. To fix this I change the WANDown queue length to 4250 and now i get +12ms. Question: Should I change anything in the tunables to compliment this change? in some of the forums they mention that if you increase the queue length, you should also change "net.inet.ip.dummynet.pipe_slot_limit" to something higher. Can you comment on this?

Thx you ! C to A+!! :):

what program do i have to install?and how?idk how intall this,any help please?

Is this a problem in OPNsense - or rather, can i use the same steps in OPNsense? I'll try the test site when my neighborhood has gone to sleep.

for some reason, I cannot get the rules to apply to and limit traffic unless I set the source to Any on each rule for ipv4 and ipv6. Any ideas why this is and if it is okay to do so?

If I want to apply it to the PIA VPN to, do I douplicate all, or is it enouge to just one more floating role?

Thanks for the quick guide! How do you handle this with (privacy) VPN gateways?

i have 1000 ms download and 800 ms upload, do these ms levels fell in games ?

can someone point me in the direction of where to obtain a pfSense router like what was used in this video? A proven make and model would be ideal for me as I don't have time to experiment. I have a 500/500 fiber ethernet network that I want to use it on. Thanks

wow.. i didn't even know this was a thing..

I have openvpn tunnel, do I need to do it also to the vpn?

Hey! Thanks! This definitely got rid of my latency BUT i now have 80% less upload speed. What happened?

Humm.. I followed a similar video from Chris Titus Tech (old video) and it added a s*** tone of floating filters.. not like your 2 filters. Perhaps i should redo them and follow yours?

What if you're using pfatt supplicant branch which breaks the traffic shaper on the wan interface?

I have 2 wan setup with load balancer group as a gateway. How would I properly setup Bufferbloat floating rules then? Should I be creating a floating rule for each Wan separately? Can anyone help me out with this?

Would it make any difference with my 50mbps down and 10mbps up internet service that I'm sharing with two other houses? Pfsense in a proxmox vm on an HP sff I5 computer. I'm using Ubiquiti 2.4ghz wireless gear. I'm in the country and the internet provider choices are limited. The internet is unlimited data which all providers should switch to. Doesn't make since why some limit the data. Im on a fixed wireless service and a wireless home network to all three houses. Two houses over 1000 feet from office where the Rocket 2AC Prism with antenna is located. The third house is 75 feet from office with two nanostation 5AC locos connection.

How do you see your buffer bloat score? Is there link we use?

I followed this to the letter and it borked my internet. Different settings may be needed with 5G based internet.

I was going to hire you to setup my stuff....Finally back in my house but the contact page guy says you dont do that now? called me a home user... wtf

What if you have vlans?do i need to change the wan ?

Is this only needed if you hit your max speed provided while gaming or on a voip call?

Is there a way to made a Video about bandwith guarantee for a Service (voip)?

and where can I check the delay?

didn't notice a difference on or off

Why is queue mgmt on Tail Drop and not CODEL?

this worsen my connection went from having A to -A and +5ms increase. weird.

i tried this and it went from D to F :-(

No more in depth conversation about prioritizing different classes of traffic or creating multiple queues or even the all-important ack queue?

I received an A+ on the bufferbloat test site without setting up any limiters, so I guess I don't need them.

These settings actually made my connection worse, I had an A to begin with so I was hoping it would make it a A+ but I fell to a B. Oh well.

what worries me is it sounds like a.. Windows 7 problem, even Linux needs to purge memory..
