I have deployed OpenStack through devstack and launched two instances in public and private subnets and created a router between public and private subnet. I am able to ping router interface from host machine but I cannot ping to a VM launched in the same public subnet.

Router interface IP =


Host Machine br-ex IP =

Security Groups = Default (All protocols are allowed for incoming and outgoing traffic)

When I ping VM from host it gives me Destination Host Unreachable error. Moreover, I have assigned a floating IP to a VM launched in private subnet but still I am unable to ping it.

Any help would be really appreciated.

The default security group blocks all incoming traffic.
