title: Envoy behind company proxy
body: <p>We're planning to use Envoy on my project, so I started fooling around with the simple examples provided on the Envoy github, and I'm facing difficulties with my company proxy.</p>
  
  <p>The first thing I tried is quite simple, serve a website www.onisep.fr (i purposely chose a site with no HTTPS) through Envoy.</p>
  
  <p>My single Envoy docker image :</p>
  
  <pre><code>FROM envoyproxy/envoy:latest
  
  ENV HTTP_PROXY http://mycompany.proxy:8080
  ENV HTTPS_PROXY http://mycompany.proxy:8080
  
  CMD apt-get update &amp;&amp; apt-get -y install curl -y
  CMD /usr/local/bin/envoy -c /etc/front-envoy.yaml --service-cluster front-proxy --log-level trace
  </code></pre>
  
  <p><strong>NB :</strong> Note the proxy configuration</p>
  
  <p>My Envoy configuration :</p>
  
  <pre><code>static_resources:
    listeners:
    - address:
        socket_address:
          address: 0.0.0.0
          port_value: 80
      filter_chains:
      - filters:
        - name: envoy.http_connection_manager
          typed_config:
            "@type": type.googleapis.com/envoy.config.filter.network.http_connection_manager.v2.HttpConnectionManager
            codec_type: auto
            stat_prefix: ingress_http
            route_config:
              name: local_route
              virtual_hosts:
              - name: simple_route
                domains:
                - "*"
                routes:
                - match:
                    prefix: "/"
                  route:
                    prefix_rewrite: "/"
                    cluster: onisep
            http_filters:
            - name: envoy.router
              typed_config: {}
    clusters:
    - name: onisep
      connect_timeout: 10.0s
      lb_policy: round_robin
      type: strict_dns
      hosts:
        socket_address:
          address: onisep.fr
          port_value: 80

    address:
      socket_address:
        address: 0.0.0.0
        port_value: 8001
  </code></pre>
  
  <p>That configuration works fine when I forward to websites that are on my company network. But as soon as I use an address that's outside this network, I'm having problems :</p>
  
  <p>In my browser :</p>
  
  <pre><code>upstream connect error or disconnect/reset before headers. reset reason: connection failure
  </code></pre>
  
  <p>In the Envoy logs :</p>

  <p>Clearly my company proxy is the problem, and Envoy cannot reach the website.
  I didn't find any resource regarding the configuration of an internet proxy within Envoy.</p>
  
  <p>What is my configuration missing ?</p>
  
  <p>Thanks</p>
