Since this seems to be just an issue with how the ruleset syntax is generated, is there a way I can manually run a fixup command or hand-edit the rules to fix this problem right now on 22.05? I have a somewhat urgent need to use limiters now...and since 22.05 is still at least 2 months away and I can't roll back my config anymore (too many changes and it's not backwards-compatible with 22.01) it would be very helpful.

Just adding some notes from redmine...

Currently this bug (#13026: Limiters do not work) appears to be blocked by the following 2 bugs:

12579 says "#12003 should be merged first" but even though progress is at 0%, it appears a patch has been merged. 13027 also has a merge request pending. Target on 13027 is 22.09—hope we don't have to wait that long to have functioning limiters again!

@jimp is there any movement going on with this (imo) important bug? Thanks

@luckman212 It's being worked on.

luckman212

@marcos-ng Good to know. I just updated to 22.05.a.20220426.1313 and was going to test a bit, but I'll keep waiting for some news on redmine.

Just reporting back here to wrap this up. I've been busy with other stuff but finally got around to retesting this. All working great on 22.05.r.20220604.1403. It's so nice to have this working again! Increased WAF factor by 10x.

@luckman212 Just one question. Did you use the same settings on post # 1 or did you change something?

Thanks.

luckman212

@betapc yes I'm using the same settings described in the guide.

@luckman212 I'm still seeing this issue in 22.05-REL?

No matter what limiter I'm putting on the WANDown it's still going full-bandwidth and bufferbloat is suffering.

That's why @luckman212 said :

Go from stock 22.05 to 22.05..r.20220604.1403 and re test ;)

netblues

@gertjan Are you sure?
Stock 22.05 was 22.05-RELEASE (amd64)
built on Wed Jun 22 18:56:13 UTC 2022
FreeBSD 12.3-STABLE

20220604 is older.
And as far as redmine says.
https://redmine.pfsense.org/issues/13026?tab=history
It has been resolved in 22.05

I stand corrected I guess.

Which brings us back to the original question regarding wandown

I just checked it on 22.05 and it DOES work.
Do a speedtest and see what speed are you getting and if it is consistent.
(eg. wan links from wisp's tend to fluctuate in speed)
And do keep in mind that wan down can only be controlled indirectly, by dropping tcp packets and hoping that ack-window will take care the rest.
If your incoming traffic is e.g. udp and there is no mechanism in the app that utilises udp traffic to request fewer data, there is no way to stop flooding your download.

@netblues I'm getting different behavior on different speedtests which is odd. Could be the UDP issue?

On Ookla and FAST, the WAN down shows as scaling correctly. And in fact on FAST it shows almost no bufferbloat.

On Waveform test, it seems to ignore the download limiter, and shows all kinds of wonky behavior around buffer bloat on download (ranging from 20ms to 120ms). Upload is steadier.

In an informal test (watching ping times to google.com while running Ookla), I am seeing significant ping impact (from 16ms to 40-70ms) under load, which suggests that something is still off.

I have been seeing really weird results on the Waveform test. It seems broken. I have a 1Gbps connection and it will show over 1200Mbps and then go all over the place showing increased latency. I have my limiter set at 940Mbps. Speedtest (Ookla) seems to respect the limiters.

netblues

@keylimesoda Try liming to a ridiculous slow rate, something like 10Mbit down., 10Mbit up and see what happens there

If the line suffers from great speed spikes limiters don't work well.
I see this on a install that has a stable ftth line, and a 5g
on the same box.
5g leaves a lot to be desired at C, while ftth is a+ on bufferbloat tests

I just went ahead and bought a TAC Pro sub. Order SO22-30515. Hope I can get some assistance next week.

Firewall > Rules > Floating:

Action: Pass
Quick: checked
Interface: WAN1
Direction: out
Family: IPv4
Protocol: any #[Change this to TCP & UDP by ctrl + click each in drop-down menu]
Source: WAN1 address
Dest: Any
Gateway: WAN1
In/Out Pipe: WAN1UpQ / WAN1DownQ

Now traceroute and icmp will operate correctly without adding extra rules.
