## Available Fields
- `MeshDestinationsOnly` `(bool: false)` - Determines whether sidecar proxies operating in transparent mode can
proxy traffic to IP addresses not registered in Consul's mesh. If enabled, traffic will only be proxied
to upstream proxies or Connect-native services. If disabled, requests will be proxied as-is to the
original destination IP address. Consul will not encrypt the connection.
