Answer
Docker configures NAT, forwarding, and bridge rules for container isolation.
Quick Answer
Docker uses iptables rules to control traffic between containers, from containers to the host, and from the host to containers. Each container network gets its own iptables chain. Docker adds rules that forward traffic appropriately, NAT outbound traffic, and drop connections that shouldn't cross network boundaries.
