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)

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)
@andreas79442 ай бұрын
Vodafone is selling 32 Customers capacity on the same 2.5 gbit link. The fastest speed is 1 gbit that you can buy at the moment. Therefore a maximum of 2 people can have that at the same time. On DSL, the overbooking ratio was way lower. Therefore it is way more relyable with better latency. And the last thing worth knowing is the messed up peering Vodafone does. It is so much worse than the telekom ones, since they try to cheap out whenever they can. In Germany, we had over 6 months of almost broken cable internet because Vodafone canceled peering contracts.

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.
@TheExtendedАй бұрын
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.

@andreas79442 ай бұрын
Totally correct. However there are other types of queues that do work better under such conditions. In regards to cable, the latency and the jitter is way worse compared to DSL. I would not recommend to use queues unless you have a real reason for that.

That's interesting; I assume you've tried CAKE autorate / adaptive bandwidth? Some Starlink & other satellite ISP users have used that with good success. CAKE is an alternative to FQ_CODEL, but it is unfortunately only on Linux-based routers (e.g., OpenWRT) and not quite yet on FreeBSD-based routers (e.g., OPNSense, etc). CAKE can be CPU-intensive to shape very high bandwidth (500Mbps+), though.

@SomeGuyWatchingYoutube2 ай бұрын
Because Rasool, the guy who invented it, says so on post ~720 in the playing with FQ_Codel forum. If you want to use the Codel queue management algorithm, you should pair it with QFQ or WFQ+ and source/destination masks. And none of that seems to apply to OPNSense, as fqcodel in OPNSense stinks without the source and destination masks. Maybe it is because of ipfw. I do kind of like OPNsense a bit more overall because of the security plugins. And they have a lot of pre-tuned netmap features. Suricata seems a bit more comprehensive in pfSense. But pfSense can be like a 18-speed tractor trailer while OPNsense an automatic with privileges.
