      @markn6262 Gotcha, yeah, I was replying to your response to me. The config I posted should work and the change you specified in your response should not be required.

      ICMP subtypes: Traceroute

      I find Win tracert does not work with your config. Ping does, however. I changed your two workaround rules to one ICMP any in/out & tracert then works.

        @gsmornot you are very fortunate. :) I'm curious, what amount of bufferbloat were you seeing before implementing shapers?

          I am not as technical with this as you guys have been but will say DSLReports gives me a D on average without the config I shared. The grade is all due to upload. Download has never been an issue here.

          I have tried the config like you posted. On average it gives me a C with an occasional B. My guess is power in the 3100 but just a guess. Keeping it simple just works best for this hardware. I will say with a config like your on my older desktop I pull out time to time I would get As. But it has much more power and needs more power which is my reason for the 3100.

            1.) Create "Out" limiter

            Tick "Enable"
            Name: FQ_CODEL_OUT
            Bandwidth: 90 Mbit/s
            Mask: None
            Queue Management Algorithm: Tail Drop
            Scheduler: FQ_CODEL

            target: 5
            interval: 100
            quantum: 1514
            limit: 10240
            flows: 1024

            Click Save/Apply Changes

            2.) Add "Out" queue

            Tick "Enable"
            Name: fq_codel_out_q
            Mask: None
            Queue Management Algorithm: Tail Drop
            Click Save/Apply Changes

            3.) Create "In" limiter

            Tick "Enable"
            Name: FQ_CODEL_IN
            Bandwidth: 90 Mbit/s
            Mask: None
            Queue Management Algorithm: Tail Drop
            Scheduler: FQ_CODEL

            target: 5
            interval: 100
            quantum: 1514
            limit: 10240
            flows: 1024

            Click Save/Apply Changes

            4.) Add "In" queue

            Tick "Enable"
            Name: fq_codel_in_q
            Mask: None
            Queue Management Algorithm: Tail Drop
            Click Save/Apply Changes

            I am attempting to duplicate your configuration, but wanted to confirm which limiter is upload and which is download so that I can set my bandwidths properly. I'm guessing that "In" is upload and "Out" is download?

              It depends on the perspective. I normally put myself in place of the device.

              So If I apply on WAN interface, "IN" is download and "OUT" is upload. So for the first floating rule matching incomming in You do regular IN/OUT, but for the second rule which matches outgoing traffic You reverse the queues.

              Still, the configuration of @uptownVagrant confuses me. I can confirm however that under load ping and traceroutes are not dropped.

                Yes, I agree. By my perspective, traffic entering (IN) the WAN port would be leaving my local network (upload). Traffic exiting (OUT) the WAN port would be entering my local network (download). IIRC this was the same perspective used by Netgate in their recent hangout regarding fq_codel. It's all a little confusing, that's why I wanted to confirm with @uptownVagrant .

                  @wgstarks I've updated the post to better explain IN and OUT. From the perspective of WAN, IN is traffic coming into the interface from the Internet, aka download, and OUT is traffic leaving the interface and bound for the Internet, aka upload. Hope that clears things up.

                    Thanks for clarifying.

                    Also (minor issue), in rules creation step 3 I couldn’t select “Default” for gateway. Had to actually pick a gateway as you did in step 4.

                      @wgstarks Make sure you are choosing "Direction: In" on that rule. IN rules do not require a gateway be selected.

                          For those interested, here is a quick comparison I ran today of ALTQ shapers using FAIRQ + CoDel and DummyNet limiters using FQ-CoDel. I set both ALTQ shapers and the limiters to 94 Mbit/s.

                          • The ALTQ shapers used a FAIRQ parent discipline and one CoDel child queue for WAN and a FAIRQ parent discipline and on CoDel child queue for LAN.
                          • The DummyNet limiters used a FQ-CoDel scheduler and one Tail Drop queue for WAN-OUT and a FQ-CoDel scheduler and one Tail Drop queue for WAN-IN. ICMP was passed before entering the limiter.

                            @uptownvagrant Thanks!

                            fq_codel is definitely better, especially for upload bandwidth, but fairq+codel is not that bad for how easy it is to setup.

                                Substitua CoDel por TailDrop. Não use o CoDel AQM com FQ-CoDel.

                                My apologies if the English to Portuguese translation is incorrect. Replace CoDel with TailDrop. Don't use CoDel AQM with FQ-CoDel.

                                      This config work perfect! for 1 wan
                                      I have 2 adsl, with balance group (tier 1 both wans).
                                      But dont know how to config the floating rules to use this balance group.
                                      The wans have different speeds.

                                      Thanks!

                                        I do not speak English, but google speaks for me KKK, create 2 floating rules one for each gateway this way :0_1544128601650_Rules.png

                                          @ricardox Thanks, I'm going to try it
                                          This is what I have
                                          WAN1 and WAN2

                                          Create 8 floating rules (following the example of @uptownVagrant )
                                          but I think that is not the correct way to achieve the desired goal
