Comment 2 for bug 1489746

you are right, it was a config issue on our side.
Basically, according to our architecture, we need to authorize the access to the management network (which is not ideal) from the jumphost.
So we added a vlan interface and moved the IP to that interface. That is why we got the connection issue. Once properly reconfigured, rally is running well (https://build.opnfv.org/ci/job/functest-fuel-stable-arno/5/console)

I should have focused on this connectivity issue message but I was mis-leaded by the first comments I saw on IRC log that were dealing with a specific configuration of the endpoint

thanks for the answer
