VMSs traffic

I installed Openstack Newton. I wan to ssh access to instances

In addition of compute and controller node, I added a gateway node to forward traffic from internet to VMs. Nodes addresses Controller 10.0.0.200 Compute 10.0.0.62 Gateway 10.0.0.201

I added iptables roules in the gateway eg. to access to dashboard I added this rule iptables -t nat -A PREROUTING -i ${EXT_NIC} -p tcp --dport 443 -j DNAT --to $10.0.0.200:443

and it's working.

My purpose now is to add rules to forward traffic to VMs My ext net is 10.0.0.0/24 floating IP range 10.0.0.241-10.0.0.242

Instance IP 10.0.0.241

When I ping the instance from the controller it works When I try to ping it from the gateway, it fails.

This made me confused It is obligatory that all VMs traffic pass through the controller ?

If no, how I can fix this ?

Thank you ^^
