Constraints and Known Issues

The following constraints and issues cause HCP Consul to function inconsistently with self-hosted Consul environments. Refer to Specifications for additional requirements:

• HVN Peering from a HashiCorp HVN to a customer's VPC/VNET only supports RFC1918 IP addresses.
• The Consul monitor command is not supported on HCP Consul.
• Concurrent use of federations and the admin partitions feature is not supported. Admin partitions are supported in HCP with Consul 1.11.x versions, but the option to federate clusters and create non-default partitions is not supported.
• You may experience issues connecting HCP Consul 1.11.0 clusters to Consul Enterprise clients versions 1.10.0-1.10.6. If you want to connect to HCP Consul versions 1.11.2 or later, we recommend using Consul Enterprise version 1.10.7 for your clients. This issue is only applicable to Consul Enterprise binaries. To learn more about defects, known issues, and fixes, refer to the Consul changelog.
• HCP Consul does not support AWS Certificate Manager as a Connect CA
