[Fiware-lab-help] Problems with fi-ware testbed

You can simply test - That's something a little bit "undefined in
behaviour" in the version of Openstack we are using. That won't be a
problem in future versions.

I don't think that adding a new security group would work, but adding
new ports to your security group is likely to work -- Just test and tell
me how it is going and maybe I can do something.

BR,
José Ignacio.
