Problem setting up tail drop/codel

@Wolf666 hi. Thanks I tried this but stil no traffic. I setup the limiters as per the article . Is yours any different. Any chance you could share your setup.. just can't seem to resolve it.. thank you

@AberDino ill try again but just can't seem to resolve it. I setup the limiters as per the article , are yours the same as this? Thanks

I am travelling, I will post it in the weekend.
My config is 1:1 with netgate guide, only 1 floating rule on WAN interface and "WAN address" as source.
I see you put "any" as source, you want to do it only on WAN address. -
@Wolf666 thank you. Ill try again.

Yes, they are, but with the target value adjusted to the 'unloaded' ping time to the first ISP hop (26ms in my case, on VDSL), as per the CoDel tuning link I posted above.

@AberDino ok thanks . I tried again but it just doesn't seem to want to work for me. Its as soon as I apply the rule. Very confused

@zennb1 Since it seems that you've been over the rule creation to assign traffic to the limiter queues multiple times and it all looks okay, perhaps double check the limiters and their associated queues and maybe post some screen shots of how you have them configured? I wonder if there's any chance your rules are working just fine, but there's something wrong with how the limiters/queues are set up.

@TheNarc thanks. agreed. I need a bit of time but will post the lot

@zennb1 Okay, what stands out to me are target and interval values of 0 for your WAN down limiter. I don't think that is valid. I feel like I've seen other posts from people claiming that somehow those can end up being defaults, but I'm betting that's what's breaking things for you.
I would start by setting target to 5 and interval to 100 like your upload limiter. As to all the other parameters, I don't feel like I can give great advice, especially for such a fast symmetric connection. To be honest, in my experience it seems like almost everywhere you look for information about how to set the few "knobs" available with FQ_CODEL, the advice is different :) But I bet that just changing those target and interval values will get traffic flowing for you.
Clearly, you can try changing various settings and test to see what works best for you. I have found some advice that the "queue length" should be set equal to "limit", and also that for an 8Gbps symmetric connection you may want "limit" and "flows" both set to something like 4096. But, I am not an expert on these FQ_CODEL settings so if anyone chimes in who is, I would defer to them.
