I executed systemctl restart iptables

I know this will clear the Docker chains

so I do systemctl restart docker to add docker chains to iptables

but now i find the docker-user chains is missing

no docker-user chains

and no docker-user policy in forward chains

iptables -nvL FORWARD

iptables -nvL DOCKER-USER

iptables: No chain/target/match by that name.

I am trying to manually create DOCKER-USER chains,and restart docker

iptables -N DOCKER-USER
iptables -A DOCKER-USER -j RETURN

and restart docker

but it did not add DOCKER-USER to FORWARD
