[Rdo-list] Failing to deploy Mitaka on baremetal

Just another update. I fixed the connectivity issue (nic1 and nic2 were
inverted in yaml files) but the setup files anyway.
The problem now, looking into the compute's
/var/lib/heat-config/deployed directory) is this one:
{
"deploy_stdout": "Trying to ping 172.16.0.14 for local network
172.16.0.0/24...SUCCESS\nTrying to ping 172.17.0.16 for local network
172.17.0.0/24...SUCCESS\nTrying to ping 172.18.0.14 for local network
172.18.0.0/24...SUCCESS\nTrying to ping default gateway
10.1.241.254...FAILURE\n10.1.241.254 is not pingable.\n",
"deploy_stderr": "",
"deploy_status_code": 1
}
Funny thing is that I'm able to ping 10.1.241.254 from the compute
nodes, and so I'm asking why it is failing during the deployment.
Should it be that something is not ready from network side? Then what?
Can you give me some hints on how to debug this?
