Answer
Docker configures NAT and DOCKER-USER chains to enforce container isolation.
Quick Answer
Docker inserts iptables rules into FORWARD, DOCKER, and DOCKER-USER chains to control traffic. DOCKER-ISOLATION chains prevent cross-network traffic. Docker manages these rules automatically when containers start and stop. Manually modifying iptables alongside Docker can break isolation if you interfere with Docker's chains.
