- Grant `service:write` permissions to services that define mesh gateways in their server definition.
- Grant `service:read` permissions for all services on the partition.
- Grant `mesh:write` permissions to the mesh gateways that participate in cluster peering connections. This permission allows a leaf certificate to be issued for mesh gateways to terminate TLS sessions for HTTP requests.

### Install Consul using Helm and configure peering over mesh gateways
To use cluster peering with Consul on Kubernetes deployments, update the Helm chart with [the required values](/consul/docs/k8s/connect/cluster-peering/tech-specs#helm-requirements). After updating the Helm chart, you can use the `consul-k8s` CLI to apply `values.yaml` to each cluster.

1. For both clusters apply the `Mesh` configuration entry values provided in [Mesh Gateway Specifications](/consul/docs/k8s/connect/cluster-peering/tech-specs#mesh-gateway-specifications) to allow establishing peering connections over mesh gateways.
### Configure the mesh gateway mode for traffic between services
In Kubernetes deployments, you can configure mesh gateways to use `local` mode so that a service dialing a service in a remote peer dials the remote mesh gateway instead of the local mesh gateway. To configure the mesh gateway mode so that this traffic always leaves through the local mesh gateway, you can use the `ProxyDefaults` CRD.
