accessibility of URLs outside of the cluster depends on the configuration of the proxy.
By default, Istio configures the Envoy proxy to pass through requests for unknown services.
Although this provides a convenient way to get started with Istio, configuring
stricter control is usually preferable.</p><p>This task shows you how to access external services in three different ways:</p><ol><li>Allow the Envoy proxy to pass requests through to services that are not configured inside the mesh.</li><li>Configure <a href=/v1.23/docs/reference/config/networking/service-entry/>service entries</a> to provide controlled access to external services.</li><li>Completely bypass the Envoy proxy for a specific range of IPs.</li></ol><h2 id=before-you-begin>Before you begin</h2><ul><li><p>Set up Istio by following the instructions in the <a href=/v1.23/docs/setup/>Installation guide</a>.

If you have

<code>meshConfig.outboundTrafficPolicy.mode</code>, that configures the sidecar handling
of external services, that is, those services that are not defined in Istio&rsquo;s internal service registry.
If this option is set to <code>ALLOW_ANY</code>, the Istio proxy lets calls to unknown services pass through.
If the option is set to <code>REGISTRY_ONLY</code>, then the Istio proxy blocks any host without an HTTP service or
service entry defined within the mesh.
<code>ALLOW_ANY</code> is the default value, allowing you to start evaluating Istio quickly,
without controlling access to external services.
You can then decide to <a href=/v1.23/docs/tasks/traffic-management/egress/egress-control/#controlled-access-to-external-services>configure access to external services</a> later.</p><ol><li><p>To see this approach in action you need to ensure that your Istio installation is configured
with the <code>meshConfig.outboundTrafficPolicy.mode</code> option set to <code>ALLOW_ANY</code>. Unless you explicitly
set it to <code>REGISTRY_ONLY</code> mode when you installed Istio, it is probably enabled by default.</p><p>If you are unsure, you can run the following command to display your mesh config:</p><pre><code class=language-bash data-expandlinks=true data-repo=istio>$ kubectl get configmap istio -n istio-system -o yaml
</code></pre><p>Unless you see an explicit setting of <code>meshConfig.outboundTrafficPolicy.mode</code> with value <code>REGISTRY_ONLY</code>,
you can be sure the option is set to <code>ALLOW_ANY</code>, which is the only other possible value and the default.</p><div><aside class="callout tip"><div class=type><svg class="large-icon"><use xlink:href="/v1.23/img/icons.svg#callout-tip"/></svg></div><div class=content><p>If you have explicitly configured <code>REGISTRY_ONLY</code> mode, you can change it

This way, you can start using Istio features on some external services without blocking any others.

any other unintentional accesses.</div></aside></div><ol><li><p>Change the <code>meshConfig.outboundTrafficPolicy.mode</code> option to <code>REGISTRY_ONLY</code>.</p><p>If you used an <code>IstioOperator</code> CR to install Istio, add the following field to your configuration:</p><pre><code class=language-yaml data-expandlinks=true data-repo=istio>spec:

you can configure the Envoy sidecars to prevent them from
<a href=/v1.23/docs/concepts/traffic-management/>intercepting</a>
external requests. To set up the bypass, change either the <code>global.proxy.includeIPRanges</code>
or the <code>global.proxy.excludeIPRanges</code> <a href=https://archive.istio.io/v1.4/docs/reference/config/installation-options/>configuration option</a> and
update the <code>istio-sidecar-injector</code> configuration map using the <code>kubectl apply</code> command. This can also
be configured on a pod by setting corresponding <a href=/v1.23/docs/reference/config/annotations/>annotations</a> such as
<code>traffic.sidecar.istio.io/includeOutboundIPRanges</code>.
After updating the <code>istio-sidecar-injector</code> configuration, it affects all

passthrough calls to unknown services,
this approach completely bypasses the sidecar, essentially disabling all of Istio&rsquo;s features
for the specified IPs. You cannot incrementally add service entries for specific
destinations, as you can with the <code>ALLOW_ANY</code> approach.
Therefore, this configuration approach is only recommended as a last resort
when, for performance or other reasons, external access cannot be configured using the sidecar.</div></aside></div><p>A simple way to exclude all external IPs from being redirected to the sidecar proxy is

</code></pre><h2 id=understanding-what-happened>Understanding what happened</h2><p>In this task you looked at three ways to call external services from an Istio mesh:</p><ol><li><p>Configuring Envoy to allow access to any external service.</p></li><li><p>Use a service entry to register an accessible external service inside the mesh. This is the
recommended approach.</p></li><li><p>Configuring the Istio sidecar to exclude external IPs from its remapped IP table.</p></li></ol><p>The first approach directs traffic through the Istio sidecar proxy, including calls to services
that are unknown inside the mesh. When using this approach,
you can&rsquo;t monitor access to external services or take advantage of Istio&rsquo;s traffic control features for them.
To easily switch to the second approach for specific services, simply create service entries for those external services.
This process allows you to initially access any external service and then later
decide whether or not to control access, enable traffic monitoring, and use traffic control features as needed.</p><p>The second approach lets you use all of the same Istio service mesh features for calls to services inside or
outside of the cluster. In this task, you learned how to monitor access to external services and set a timeout
rule for calls to an external service.</p><p>The third approach bypasses the Istio sidecar proxy, giving your services direct access to any external server.
However, configuring the proxy this way does require cluster-provider specific knowledge and configuration.
Similar to the first approach, you also lose monitoring of access to external services and you can&rsquo;t apply
Istio features on traffic to external services.</p><h2 id=security-note>Security note</h2><div><aside class="callout warning"><div class=type><svg class="large-icon"><use xlink:href="/v1.23/img/icons.svg#callout-warning"/></svg></div><div class=content>Note that configuration examples in this task <strong>do not enable secure egress traffic control</strong> in Istio.
