Did any colleague successfully use FWMARK?
Here I am trying to do a test marking an IP destination so that it does not go through the Accel SHAPER.
The problem is that Accel's QoS is not recognized as packet marking!
Alga managed to make or fwmark work?

iptables -A FORWARD -t mangle -j CONNMARK --restore-mark
iptables -A FORWARD -t mangle -m mark ! --mark 0 -j ACCEPT
iptables -A FORWARD -t mangle -s IP_DESTINATION/32 -j MARK --set-mark 38
iptables -A FORWARD -t mangle -d IP_DESTINATION/32 -j MARK --set-mark 38
iptables -A FORWARD -t mangle -j CONNMARK --save-mark

Hi @EmanuelMCunha fwmark works only for client download

Do you see iptables counters?

iptables -t  mangle -L -n -v

Yes Counters score perfectly!

Show me, and also provide [shaer] section

The strangest and that in command:
tc filter show
dont show nothing!

[shaper]
verbose=1
vendor=Cisco
attr=Cisco-AVPair
#attr=Filter-Id
ifb=ifb0
#up-limiter=police
up-limiter=htb
down-limiter=tbf
fwmark=38

use htb for down-limiter if you want using fwmark

which attributes recived from radius?

show me log, with entry shaper installed

debug.log ?

no, just accel-ppp log with level=5 =)

note for history: after daemon restart all work

Нужно наверное указать что fwmark работает только с htb

Есть ли способ использовать параметры Mikrotik в ускорении? Я видел, что есть патч для преобразования значений Mikrotik в стандарт Accel. Существуют негибкие системы, которые отправляют только параметры микротика.

Is there any way to use Mikrotik parameters in the accel? I saw that there is a patch to convert Mikrotik values to the Accel standard. There are some non-flexible systems that only send mikrotik parameters.

Yes, it is possible with [shaper]vendor=Mikrotik
