Can you give the following information: * how many containers are running on the host ? For the host and the containers: * 'ip addr show' * ip neigh show * 'brctl show' And a tcpdump : tcpdump -i any dst or src <containerip> And then try to ping or connect to/from the container to make tcpdump show something.
