CloudStack supports guest networks of type isolated and shared. While there is rich support of L4-L7 network services like firewall, NAT, LB in the isolated networks, similar network services are not available in the networks of shared type. While there is EIP and ELB services which provides NAT and LB service in basic zone which uses shared network, there are no firewall, NAT, LB services available to the shared networks created in the advanced zone. For enterprise/private clouds and simple deployments it make sense to enable L4-L7 services in the shared networks. I am proposing that CloudStack should enable L4-L7 network services in the shared networks created in the advanced zone. I opened new feature request for 4.1 release [1] and documented the functional requirements at [2]. Please comment.
