[Openstack-operators] Instances can't reach metadata server in network HA mode

My set up is a nova-network-ha<http://docs.openstack.org/trunk/openstack-compute/admin/content/existing-ha-networking-options.html>,
so each of my nodes run a nova-{api-metadata,network,compute,volume}, my
controller runs all of this plus the rest of things it should run.
Each of my nodes are the gateway for it's own instances. They all have the
same net config, ip_forwarding.

The main issue is that I can't telnet the nodes on port 80 that should
redirect to metadatas server. metadata IP is set correctly to eth0, but 80
port is not open.
My doubt is, should I create a endpoint for each node api-metadata service?
should I install apache on nodes?

I really don't know what to do anymore. This only happen on nodes, on
cloudcontroller all instance run smoothly. they get the floatip, metadata
service, etc.

Thanks in advance!


I will put the max of info I can here.
