[I am running pihole on raspberry pi ubuntu server 20.04 on a docker image, docker exposed my ports to the internet, I am running pihole web interface on port 8080 which should be accessible only on the local network, but it got exposed to the internet, and container ignoring my UFW rules, I tried adding **iptables -I DOCKER-USER -i ext_if ! -s 192.168.1.0/24 -j DROP** to my IP tables but this killed pi-hole]
