No se puede comunicar del host al contenedor y viceversa

Question

Tengo una instancia de GitLab ejecutándose en la ventana acoplable. Pero no puedo hacer ping ni activar el puerto 8000.

CONTAINER ID   IMAGE                     COMMAND                  CREATED        STATUS                  PORTS                                                              NAMES

docker network inspect bridge

    {
        "Name": "bridge",
        "Driver": "bridge",
        "EnableIPv6": false,
        "Containers": {
            "d31649b89354209a33095536f13ac67271d5ebb632a9a2cabf41706036f139ea": {
                "Name": "gitlab_web_1",
                "EndpointID": "c3c3514a8eb3b9e9d3773debf39f1388179475941e8c5572c98851c3dfe262f3",
                "MacAddress": "02:42:ac:11:00:02",
                "IPv4Address": "172.17.0.2/16",
                "IPv6Address": ""
            }
        },

Cuando intento hacer ping al contenedor, aparece un error.

ping 172.17.0.2
PING 172.17.0.2 (172.17.0.2) 56(84) bytes of data.

From 172.17.0.1 icmp_seq=3 Destination Host Unreachable
From 172.17.0.1 icmp_seq=4 Destination Host Unreachable

Pero si ejecuto un tcpdump -i docker0, el ping se ejecuta correctamente.
