VLANs and subnets in VMware Solutions

The following table provides information about the subnets that are used in each VLAN. You can either order new VLANs or subnets for VMware Cloud Foundation for Classic - Automated instances or you can select existing VLANs. You can define your firewall rules based on the subnets and ports that the network traffic goes through.

It is not recommended to put a firewall on a secondary private VLAN that has storage and vSphere® vMotion® traffic.
