Hello,
is there an incompatibilty between wireguard and traffic shaping or i
misconfig something  ?

After configuring Qos , I need to add filter to flow

If i'm trying with simple tc command :
tc filter add dev wg0 protocol ip parent 1: prio 10 u32 match ip dport 80
0xffff flowid 1:10

or If i'm trying with tc + iptables,

tc filter add dev wg0 protocol ip parent 1: prio 1 handle 6 fw flowid 1:10
and iptables mark rules,

traffic seems to be not "apply" to queue .

Regards,
Nicolas Prochazka.

Example :  after this configuration, traffic on wg0 on port 80,443,8080 are
going to 1:30 ,not to 1:10
_trafficShappingMaxRate=15

tc qdisc del dev wg0 root

tc qdisc add dev wg0 root handle 1: htb default 30

# Base
tc class add dev wg0 parent 1: classid 1:1 htb rate
${_trafficShappingMaxRate}mbit burst 15k

# http/https

# Class 1:10,
tc class add dev wg0 parent 1:1 classid 1:10 htb rate
${_trafficShappingMaxRate}mbit ceil ${_trafficShappingMaxRate} burst 15k

# Class 1:20,
tc class add dev wg0 parent 1:1 classid 1:20 htb rate
${_trafficShappingMaxRate}mbit ceil ${_trafficShappingMaxRate}mbit burst 15k

# Class 1:30, which has a rate of 1kbit. This one is the default class.
tc class add dev wg0 parent 1:1 classid 1:30 htb rate 10kbit ceil 1mbit
burst 15k

tc qdisc add dev wg0 parent 1:10 handle 10: fq_codel quantum 300 noecn
tc qdisc add dev wg0 parent 1:20 handle 20: fq_codel quantum 300 noecn
tc qdisc add dev wg0 parent 1:30 handle 30: fq_codel quantum 300 noecn

# --- associate queue with traffic

#tc filter add dev wg0 protocol ipv6 parent 1: prio 1 handle 6 fw flowid
1:10
# http/https
tc filter add dev wg0 protocol ipv6 parent 1: prio 10 u32 match ip dport 80
0xffff flowid 1:10
tc filter add dev wg0 protocol ipv6 parent 1: prio 10 u32 match ip dport
443 0xffff flowid 1:10
tc filter add dev wg0 protocol ipv6 parent 1: prio 10 u32 match ip dport
8080 0xffff flowid 1:10
# ncfs
tc filter add dev wg0 parent 1: protocol ipv6 prio 5 u32 match ip dport
16379 0xffff flowid 1:20
# icmp
tc filter add dev wg0 parent 1: protocol ip prio 1 u32 match  ip protocol 1
0xff flowid 1:30

tc -s qdisc ls dev wg0
