Re: Is that safe to put public IP directly on Virtual Router/ System VMs?

Hi Eric,

Usual setup for my other infra service is that we use external firewall
doing NAT and protecting the resource behind. The public IP will stay on
that firewall and it is NATed to private IP of the service internal.

What CS document imply is to put “real” public IP address on System VMs and
VR which will leave those systems exposed directly to outside world.

My question is if that architecture is recommeneded and how safe it is to
put “real” public IP on System VMs and VRs directly.

Thanks in advance,
