Controlling Traffic Flow Over the Connection
Even if a connection has been established between your VCN and VNet, you can control the packet flow over the connection with route tables in your VCN. For example, you can restrict traf-fic to only specific subnets in the VNet.
Controlling the Specific Types of Traffic Allowed
It's important that you ensure that all outbound and inbound traffic with the VNet is intended or expected and well defined. Implement Azure network security group and Oracle security rules that explicitly state the types of traffic one cloud can send to the other and accept from the other.
