[openstack-dev] [Neutron] Problem connecting from host to router and VM port under DevStack

Hi,

I had this working once, but after rebooting my host and restarting devstack, I cannot get it to work. Hoping someone has an idea…

Running latest devstack with OVS and GRE tunnels.

In Openstack, I added a network, subnet, and router, and have opened up security groups:

neutron net-create mgmt
neutron subnet-create --disable-dhcp --name=mgmt-subnet mgmt 192.168.200.0/24
neutron router-create router2
neutron router-interface-add router2 mgmt-subnet
sudo ovs-vsctl add-port br-int my_port tag=2 -- set interface my_port type=internal
sudo ifconfig my_port 192.168.200.3/24 up
nova secgroup-add-rule default icmp -1 -1 0.0.0.0/0
nova secgroup-add-rule default tcp 22 22 0.0.0.0/0

From the host, I cannot ping the router interface (192.168.200.1), nor can I ping the host (192.168.200.3) from the router's namespace. I had created a VM with an interface on the subnet (192.168.200.2), and I can ping the router from the VM and vice versa.

With the private and public network, I can ping the router from the host w/o any issue.

Any idea as to what I'm missing?

Thanks!
