5.6.3 Organization Virtual Datacenter Networks
Create two different organization virtual datacenter networks for each organization: one routed external organization virtual datacenter network, and one internal organization virtual datacenter network. The Create Organization Network wizard provides the option of creating these two organization virtual datacenter networks in one workflow. When naming an organization virtual datacenter network, start with the organization name and a hyphen, for example, “Company1-Internet.”
The routed external organization virtual datacenter network uses vCloud Networking and Security Edge for firewall and NAT services to isolate organization traffic from other organizations that share the same external provider network. Both the external organization virtual datacenter network and the internal organization virtual datacenter networks are instantiated from the previously established vCloud Director Network Isolation network pool. Each organization virtual datacenter network requires network configuration settings and a pool of IP addresses. Because both networks are private networks, you can use RFC 1918 addresses for each static IP address pool. The static IP address pool can be as large as desired. Typically an RFC 1918 class C is used.
The last step is to add external public IP addresses to the vCloud Networking and Security Edge configuration on the external organization virtual datacenter network. Using the Configure Services interface, add eight public IP addresses to an external organization virtual datacenter network. The IP addresses listed come from the external network static IP address pool.
