### [newbie] Floating ips not reacheable

Hope you can help me. I am blind looking at docs and testing things but I cannot make my packstack instances being seen outside the host. I am not either a network expert

Using ESXi to install packstack --allinone --provision-all-in-one-ovs-bridge=n

I am using an existing network 10.128.106.0/23 but I just want to use few ips on that range 10.128.106.240-248

All connections between instances and host work fine, but I cannot reach the instances 10.128.106.242/243 from outside, and once inside the instance, I cannot ping any system in the network but 10.128.106.82 (the main HOST).

| ID | Name | Status | Task State | Power State | Networks

After reading "Step 10. Getting VMs to Communicate with the Outside World" in https://openstack.redhat.com/PackStack_All-in-One_DIY_Configuration I could confirm that it looks fine but I configured the NAT part at the end but it didn't work either.

A funny thing is that when I ping one of the floating-ip addresses, the tcpdump registers the arp and provides the right MAC.

could it be that VMware vSwitch is droping the packages ?

And this is the part of the router
