  [SMTP Upstream] --- raw SMTP --- [L2 Envoy] --- SMTP tunneled over HTTP/2 --- [L1 Envoy] --- raw SMTP --- [Client]
  Examples of such a set up can be found in the Envoy example config :repo:`directory <configs/>`
  -If you run `bazel-bin/source/exe/envoy-static --config-path configs/encapsulate_in_connect.yaml --base-id 1`

  +and `bazel-bin/source/exe/envoy-static --config-path configs/terminate_connect.v3.yaml`
  you will be running two Envoys, the first listening for TCP traffic on port 10000 and encapsulating it in an HTTP/2
  CONNECT request, and the second listening for HTTP/2 on 10001, stripping the CONNECT headers, and forwarding the
  original TCP upstream, in this case to google.com.
