Traffic mirror source and target connectivity options
The traffic mirror source and the traffic mirror target (monitoring appliance) can be in the same VPC or different VPCs and can be connected using the following resources:
An intra-Region VPC peering connection.
A transit gateway.
A Gateway Load Balancer endpoint.
The traffic mirror target can be owned by an AWS account that is different from the traffic mirror source.
The mirrored traffic is sent to the traffic mirror target using the source VPC route table. Before you configure Traffic Mirroring, make sure that the traffic mirror source can route to the traffic mirror target.
The following table describes the available resource configurations.
Source owner | Source VPC | Target owner | Target VPC | Connectivity option |
---|---|---|---|---|
Account A | VPC 1 | Account A | VPC1 | No additional configuration |
Account A | VPC 1 | Account A | VPC 2 | Intra-Region peering or a transit gateway or Gateway Load Balancer endpoint |
Account A | VPC 1 | Account B | VPC 2 | Cross-account intra-Region peering connection, a transit gateway, or a Gateway Load Balancer endpoint |
Account A | VPC 1 | Account B | VPC 1 | VPC sharing |
