VPC peering

Crunchy Bridge instances run in an isolated network or VPC (a logically isolated Virtual Private Cloud). Your network is fully isolated from other customers and from other teams within your account. By default your VPC is configured to be publicly available with a firewall rule of It is recommended for further security you setup specific firewall rules for your environment’s access only.

Crunchy Bridge supports VPC peering to enable your Crunchy Bridge cluster’s VPC to communicate over a private network route with another VPC under your control. In order to configure VPC peering, please open a support ticket.

Note that the firewall rules for a cluster apply to both public and private (peered) traffic. If you enable VPC peering, and leave the firewall rules set to the default of, your database cluster will be accessible via public IPs as well as the private network of the VPC peer. To fully secure your cluster in a VPC peering arrangement, be sure to update the firewall rules to match the private network address space of the peered VPC.
