Hi Bryce, The preferred method of assigning traffic is storage and management traffic can be assigned with ip ranges from private network 10.1.4.0/23. Guest traffic can be with default CIDR what CS gives while deploying zone and public traffic can be with your public network 192.168.56.0/24
Guest and management can't be in the same private network. As you mentioned in your previous mail , if you had assigned 10.1.4.0/23 as guest CIDR and eth0 NIC was configured with 10.1.4.0/23 there could be a possibility of IP duplication. CS will select the ip address randomly from guest CIDR while deploying vm . So if the CS selected ip address is already assigned to eth0 NIC on the hypervisor then ip duplication will occur. So CS does not allow adding guest and management traffic in the same CIDR.

I'm trying to get my head around provisioning a cluster in cloudstack 4.0.2...specifically issues surrounding networking. I have been looking for a good tutorial, but have not googled my way into one yet. My config is very very simple: one management server and one host. I have two physical networks: "public" and "private". Cloudstack "public" traffic is the only thing on my public network, all other cloudstack traffic is confined to the private network. While I intend to grow this setup, I do not envision that the essential networking situation will change. The system is managed via the StackIQ Rocks+Cloud roll. The eth0 NICs are configured as the private network 10.1.4.0/23, having their own superdumb GigE switch. The eth1 NICs form the "public" network 192.168.56.0/24 and are plugged into the University managed switches. This isn't really "public", but I can get to them from the University network. I've been allocated a block of 50 IPs on this University-public network. The management server (10.1.4.1) also serves DNS for the private network, and serves as a gateway to the public world. I'm having problems getting all four cloudstack traffic types to coexist on these two networks. The Zone's Guest CIDR is 10.1.4.0/23. The GUI is returning an error when launching my config ("The subnet of the pod you are adding conflicts with the subnet of the Guest IP Network"). The pod was given 10.1.4.0/23 also, with the reserved system IPs of 10.1.4.10-10.1.4.20. Storage traffic, similarly, has been dispatched to the private network with IPs of 10.1.4.40-10.1.4.50. It hasn't complained about this yet, but it might be waiting. My question is either: "What did I do wrong, above?" or "What is the preferred method of assigning storage, guest, and management traffic to a private network and public traffic to a public network (e.g., what numbers go where in the provisioning process?)"
