# Mesh Gateways
Mesh gateways enable service mesh traffic to be routed between different Consul datacenters.
Datacenters can reside in different clouds or runtime environments where general interconnectivity between all services in all datacenters isn't feasible.
## Prerequisites
Mesh gateways can be used with any of the following Consul configrations for managing separate datacenters or partitions.
1. WAN Federation
* [Mesh gateways can be used to route service-to-service traffic between datacenters](/docs/connect/gateways/mesh-gateway/service-to-service-traffic-wan-datacenters)
* [Mesh gateways can be used to route all WAN traffic, including from Consul servers](/docs/connect/gateways/mesh-gateway/wan-federation-via-mesh-gateways)
2. Cluster Peering
* [Mesh gateways can be used to route service-to-service traffic between datacenters](/docs/connect/gateways/mesh-gateway/service-to-service-traffic-peers)
* [Mesh gateways can be used to route control-plane traffic from Consul servers](/docs/connect/gateways/mesh-gateway/peering-via-mesh-gateways)
3. Admin Partitions
* [Mesh gateways can be used to route service-to-service traffic between admin partitions in the same Consul datacenter](/docs/connect/gateways/mesh-gateway/service-to-service-traffic-partitions)
### Consul
Review the [specific guide](#prerequisites) for your use case to determined the required version of Consul.
### Network
* General network connectivity to all services within its local Consul datacenter.
* General network connectivity to all mesh gateways within remote Consul datacenters.
### Proxy
Envoy is the only proxy with mesh gateway capabilities in Consul.
Mesh gateway proxies receive their configuration through Consul, which automatically generates it based on the proxy's registration.
Consul can only translate mesh gateway registration information into Envoy configuration.
Sidecar proxies that send traffic to an upstream service through a gateway need to know the location of that gateway. They discover the gateway based on their sidecar proxy registrations. Consul can only translate the gateway registration information into Envoy configuration.
Sidecar proxies that do not send upstream traffic through a gateway are not affected when you deploy gateways. If you are using Consul's built-in proxy as a Connect sidecar it will continue to work for intra-datacenter traffic and will receive incoming traffic even if that traffic has passed through a gateway.
## Configuration
Configure the following settings to register the mesh gateway as a service in Consul.
* Specify `mesh-gateway` in the `kind` field to register the gateway with Consul.
* Configure the `proxy.upstreams` parameters to route traffic to the correct service, namespace, and datacenter. Refer to the [`upstreams` documentation](/docs/connect/registration/service-registration#upstream-configuration-reference) for details. The service `proxy.upstreams.destination_name` is always required. The `proxy.upstreams.datacenter` must be configured to enable cross-datacenter traffic. The `proxy.upstreams.destination_namespace` configuration is only necessary if the destination service is in a different namespace.
* Define the `Proxy.Config` settings using opaque parameters compatible with your proxy (i.e., Envoy). For Envoy, refer to the [Gateway Options](/docs/connect/proxies/envoy#gateway-options) and [Escape-hatch Overrides](/docs/connect/proxies/envoy#escape-hatch-overrides) documentation for additional configuration information.
* If ACLs are enabled, a token granting `service:write` for the gateway's service name and `service:read` for all services in the datacenter or partition must be added to the gateway's service definition. These permissions authorize the token to route communications for other Consul service mesh services, but does not allow decrypting any of their communications.
### Modes
Each upstream associated with a service mesh proxy can be configured so that it is routed through a mesh gateway.
Depending on your network, the proxy's connection to the gateway can operate in one of the following modes:
* `none` - No gateway is used and a service mesh connect proxy makes its outbound connections directly
to the destination services. This is the default for WAN federation. This setting is invalid for peered clusters
and will be treated as remote instead.
* `local` - The service mesh connect proxy makes an outbound connection to a gateway running in the
same datacenter. That gateway is responsible for ensuring that the data is forwarded to gateways in the destination datacenter.
* `remote` - The service mesh proxy makes an outbound connection to a gateway running in the destination datacenter.
The gateway forwards the data to the final destination service. This is the default for peered clusters.
### Connect Proxy Configuration
Set the proxy to the preferred [mode](#modes) to configure the service mesh proxy. You can specify the mode globally or within child configurations to control proxy behaviors at a lower level. Consul recognizes the following order of precedence if the gateway mode is configured in multiple locations the order of precedence:
1. Upstream definition (highest priority)
2. Service instance definition
3. Centralized `service-defaults` configuration entry
4. Centralized `proxy-defaults` configuration entry
## Example Configurations
Use the following example configurations to help you understand some of the common scenarios.
### Enabling Gateways Globally
The following `proxy-defaults` configuration will enable gateways for all Connect services in the `local` mode.
<CodeTabs heading="Example: Enabling gateways globally.">
```hcl
Kind = "proxy-defaults"
Name = "global"
MeshGateway {
Mode = "local"
}
```
```yaml
Kind: proxy-defaults
MeshGateway:
- Mode: local
Name: global
```
</CodeTabs>
### Enabling Gateways Per Service
The following `service-defaults` configuration will enable gateways for all Connect services with the name `web`.
<CodeTabs heading="Example: Enabling gateways per service.">
```hcl
Kind = "service-defaults"
Name = "web"
MeshGateway {
Mode = "local"
}
```
```yaml
Kind: service-defaults
MeshGateway:
- Mode: local
Name: web
```
</CodeTabs>
### Enabling Gateways for a Service Instance
The following [Proxy Service Registration](/docs/connect/registration/service-registration)
definition will enable gateways for the service instance in the `remote` mode.
<CodeTabs heading="Example: Enabling gateways for a service instance.">
```hcl
service {
name = "web-sidecar-proxy"
kind = "connect-proxy"
port = 8181
proxy {
destination_service_name = "web"
mesh_gateway {
mode = "remote"
}
upstreams = [
{
destination_name = "api"
datacenter = "secondary"
local_bind_port = 10000
}
]
}
}
# Or alternatively inline with the service definition:
service {
name = "web"
port = 8181
connect {
sidecar_service {
proxy {
mesh_gateway {
mode = "remote"
}
upstreams = [
{
destination_name = "api"
datacenter = "secondary"
local_bind_port = 10000
}
]
}
}
}
}
```
```yaml
service:
- kind: connect-proxy
name: web-sidecar-proxy
port: 8181
proxy:
- destination_service_name: web
mesh_gateway:
- mode: remote
upstreams:
- datacenter: secondary
destination_name: api
local_bind_port: 100
```
</CodeTabs>
### Enabling Gateways for a Proxy Upstream
The following service definition will enable gateways in the `local` mode for one upstream, the `remote` mode for a second upstream and will disable gateways for a third upstream.
<CodeTabs heading="Example: Enabling gateways for a proxy upstream.">
```hcl
service {
name = "web-sidecar-proxy"
kind = "connect-proxy"
port = 8181
proxy {
destination_service_name = "web"
upstreams = [
{
destination_name = "api"
local_bind_port = 10000
mesh_gateway {
mode = "remote"
}
},
{
destination_name = "db"
local_bind_port = 10001
mesh_gateway {
mode = "local"
}
},
{
destination_name = "logging"
local_bind_port = 10002
mesh_gateway {
mode = "none"
}
},
]
}
}
```
```yaml
service:
- kind: connect-proxy
name: web-sidecar-proxy
port: 8181
proxy:
- destination_service_name: web
upstreams:
- destination_name: api
local_bind_port: 10000
mesh_gateway:
- mode: remote
- destination_name: db
local_bind_port: 10001
mesh_gateway:
- mode: local
- destination_name: logging
local_bind_port: 10002
mesh_gateway:
- mode: none

Mesh gateways are specialized proxies that route data between services that cannot communicate directly. Learn how to enable traffic across clusters in different datacenters or admin partitions that have an established peering connection.

# Mesh Gateways for Peering Control Plane Traffic
In addition to [service-to-service traffic routing](/docs/connect/gateways/mesh-gateway/service-to-service-traffic-peers), mesh gateways can optionally be used to route control-plane traffic between peers.
This includes the initial secret handshake and the bi-directional stream replicating peering data.
This data is not decrypted by the mesh gateway(s).
Instead, it is transmitted end-to-end using the accepting clusters auto-generated TLS certificate on the gRPC TLS port.
## Prerequisites
To configure mesh gateways for cluster peering control plane traffic, make sure your Consul environment meets the following requirements:
- Consul version 1.14.0 or newer.
- A local Consul agent in both clusters is required to manage mesh gateway configuration.
- Use [Envoy proxies](/docs/connect/proxies/envoy). Envoy is the only proxy with mesh gateway capabilities in Consul.
## Configuration
Configure the following settings to register and use the mesh gateway as a service in Consul.
### Gateway registration
Register a mesh gateway in each of cluster that will be peered.
- Specify `mesh-gateway` in the `kind` field to register the gateway with Consul.
- Define the `Proxy.Config` settings using opaque parameters compatible with your proxy. For Envoy, refer to the [Gateway Options](/docs/connect/proxies/envoy#gateway-options) and [Escape-hatch Overrides](/docs/connect/proxies/envoy#escape-hatch-overrides) documentation for additional configuration information.
- Apply a [Mesh config entry](/docs/connect/config-entries/mesh#peer-through-mesh-gateways) with `PeerThroughMeshGateways = true`. See [modes](#modes) for a discussion of when to apply this.
Alternatively, you can also use the CLI to spin up and register a gateway in Consul. For additional information, refer to the [`consul connect envoy` command](/commands/connect/envoy#mesh-gateways).
For Consul Enterprise clusters, mesh gateways must be registered in the "default" partition because this is implicitly where Consul servers are assigned.
### ACL configuration
- If ACLs are enabled, you must add a token granting `service:write` for the gateway's service name and `service:read` for all services in the "default" Enterprise admin partition or OSS datacenter to the gateway's service definition.
These permissions authorize the token to route communications for other Consul service mesh services.
### Modes
Connect proxy configuration [Modes](/docs/connect/gateways/mesh-gateway#connect-proxy-configuration#modes) are not applicable to peering control plane traffic.
The flow of control plane traffic through the gateway is implied by the presence of a [Mesh config entry](/docs/connect/config-entries/mesh#peer-through-mesh-gateways) with `PeerThroughMeshGateways = true`.
<CodeTabs heading="Example: Enabling Peering Control Plane Traffic for Mesh Gateways">
```hcl
Kind = "mesh"
Peering {
PeerThroughMeshGateways = true
}
```
```yaml
Kind: mesh
Peeering:
PeerThroughMeshGateways: true
```
</CodeTabs>
By setting this mesh config on a cluster before [creating a peering token](/docs/connect/cluster-peering/create-manage-peering#create-a-peering-token), inbound control plane traffic will be sent through the mesh gateway registered this cluster, also known the accepting cluster.
As mesh gateway instances register and leave the accepting cluster, their addresses will be exposed to the dialing cluster over the bi-directional peering stream.
Setting this mesh config on a cluster before [establishing a connection](/docs/connect/cluster-peering/create-manage-peering#establish-a-connection-between-clusters) will cause the outbound control plane traffic to flow through the mesh gateway.
To route all peering control plane traffic though mesh gateways, both the accepting and dialing cluster must have the mesh config entry applied.
