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.

Cc_cdg.ko depends on h_ertt, so both modules need to be there, otherwise cdg will fail kload.
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.
-
now the pf 2.5 version not work for this .
-
why pfsense v2.5 cant load the freebsd v12.1 cc_htcp so on?
kldload h_ertt kldload: an error occurred while loading module h_ertt. Please check dmesg(8) for more details. [2.5.0-DEVELOPMENT][admin@]/root: kldload cc_htcp kldload: an error occurred while loading module cc_htcp. Please check dmesg(8) for more details -
pf 2.4.5 -p1 still work, pf2.5 not work, added cdg

@yon-0 Liked your consistent testing ... good job!
-
@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.

Have a chance to learn from you.
