## Technical preview constraints
Not all features and functionality are available in the technical preview release. In particular, consider the following technical constraints:
- Consul ACLs must be disabled or the ACL `default_policy` must be set to `allow`.
- Mesh gateways for _server to server traffic_ are not available. However, mesh gateways for _service to service traffic_ between clusters are available.
- Services exported to peered clusters must not be configured as HTTP.
- Support for dynamic routing such as splits, custom routes, or redirects is not available.
