+  * Secure the ports Docker publishes. Rules in a chain of their own,
+    VPN-ROUTER-DOCKER, entered by a jump at the top of DOCKER-USER, accept
+    IPsec protected traffic, TCP to docker.exposed_ports and established
+    connections from the external interface and drop the rest of it. Other
+    rules in DOCKER-USER are left alone. The rules cover IPv4 only.
+  * Add the docker configuration section. docker.mode is auto (the default,
+    secures Docker when docker.service is installed), on (requires Docker) or
+    off (removes the rules); docker.exposed_ports lists the TCP ports and port
+    ranges reachable from the external interface, none by default.
+  * Add the vpn-router-docker service, which applies the Docker rules after
+    docker.service starts and removes them when it stops. vpn-router-setup
+    restarts it while Docker runs, so a changed configuration takes effect.
+  * Installing Docker before this package is recommended. When Docker is
+    installed later, restart vpn-router-setup to apply the rules.
