# Connect Proxies
|
|
|
|
A Connect-aware proxy enables unmodified applications to use Connect. A
|
|
per-service proxy sidecar transparently handles inbound and outbound service
|
|
connections, automatically wrapping and verifying TLS connections. Consul
|
|
includes its own built-in L4 proxy and has first class support for Envoy. You
|
|
can chose other proxies to plug in as well. This section describes how to
|
|
configure Envoy or the built-in proxy using Connect, and how to integrate the
|
|
proxy of your choice.
|
|
|
|
To ensure that services only meke allow external connections are established via
|
|
the Connect protocol they should only accept connections on a loopback address.
|
|
|
|
~> **Deprecation Note:** Managed Proxies are a deprecated method for deploying
|
|
sidecar proxies, as of Consul 1.3. See [managed proxy
|
|
deprecation](/docs/connect/proxies/managed-deprecated.html) for more
|
|
information. If you are using managed proxies we strongly recommend that you
|
|
switch service definitions for registering proxies.

## Dynamic Upstreams Require Native Integration
|
|
|
|
If an application requires dynamic dependencies that are only available
|
|
at runtime, it must [natively integrate](/docs/connect/native.html)
|
|
with Connect. After natively integrating, the HTTP API or
|
|
[DNS interface](/docs/agent/dns.html#connect-capable-service-lookups)
|
|
can be used.
|
|
|
|
!> Connect proxies do not currently support dynamic upstreams.
