To ensure vCloud Availability for Cloud-to-Cloud DR services can communicate within a single site and between source and destination sites, make sure that the required network ports are opened. The network port configuration is different for deployments with and without a Cloud-to-Cloud Tunneling.

Network Port Configuration for Deployments Without Cloud-to-Cloud Tunneling

The following table shows the network ports required for a local site communication between vCloud Availability for Cloud-to-Cloud DR services.
