Julien: no directly internet access is required for "pxebr", but the node
which Fuel master deployed should have internet access.
During the deployment, Fuel master will the check the internet
accessible through ping during configure stage and fetch packages during
Usually the deploy the Fuel master as VM and all the response in
the following based on this assumption.

Julien: Use static route is OK and SNAT should be used for Fuel master.
please also check whether the firewall in the jumpser blocks the packages.

Julien: I would prefer a separate network. You can refer the configuration
in securedlab repo.

Julien: Usually we configure the LOM address statically or we can not keep
consistent relationship with hardware and management IP address.
