docker containers lost communication

[matheus-neu]

this is my ufw-docker code

*filter
:ufw-user-forward - [0:0]
:ufw-docker-logging-deny - [0:0]
:DOCKER-USER - [0:0]
-A DOCKER-USER -j ufw-user-forward

when i enable the ufw, all the containers lost communication, deluge doesn't communicate with sonarr, everything in dashy turns off, what can i do?

[matheus-neu]

when i put these rules on ufw

ufw allow in on docker0
ufw allow out on docker0

the containers can communicate, but it's secure?
