I would put it in loader.conf.local and see if pfsense will load it at boot then. If you see no change, then, perhaps, the reason for your dropped packets is not congestion. Could be buffer overrun. Have you tweaked your TCP buffers and receive/send spaces ?
my wan route in show packet loss.

It appears that most errors are being logged on your LAGG port. I am going to assume that the same errors are not showing on the stats for the LAGG members ? If that is the case, only time I've seen this behavior is when you have ports LAGGed but not all of them have actual active links, so say, you have igb0 thru igb3 in a LAGG conf, but igb1 is actually disconnected (Physically). Other than that, I am unsure what the issue might be. Sorry.

thanks, What should I check or how to determine the problem? i am using two intel I350-T2 NIC. one nic two interface for pppoe wan, and one for lagged to LAN switch.

Typically when you see counters for packets not forwardable in netstat, it is because you are missing a route to localhost.

What rules or routes do I need to add?

@yon-0 Hard to say without a visual, but I will ask this : If the issue does happen on 2.4.4p3, there is a possibility, albeit small, that there may be a bug in the PPPoE client.

what's CUBIC need load modules?

cc_cubic.ko is the name.

cubic and cdg still unable to solve the problem of no speed caused by carrier network packet loss. There is a need to increase competitiveness and prevent the impact of ISP QOS on us.

@yon-0 Sorry about the lack of response. I was unaware you'd replied. Unfortunately, I've moved on to a competing product which is already on the freebsd 12.1 release in production and has ZERO issues with any and all mods to the underlying OS.

what is your using system now? i have try opnsense, But I am not very familiar with it, and there are some usage problems.
Yes, there are a lot of system problems here. Many of them are too late to report, and there are still many problems that have not been reported. It's just that I have been using it and the operation is more familiar.
-
@yon-0 Opnsense 20.7.1. Modules are readily available in the OS and load without issue. I have used htcp, cdg and cubic. Currently on Cubic and works quite well. Also, seems to be better at respecting loader.conf and loader.conf.local mods. No hardcoded kernel patches that I am aware of anyway.
