|
|
This may not match the actual client IP address if Spring Cloud Gateway sits behind a proxy layer.</p><p>You can customize the way that the remote address is resolved by setting a custom <code class="literal">RemoteAddressResolver</code>.
|
|
Spring Cloud Gateway comes with one non-default remote address resolver which is based off of the <a class="link" href="https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/X-Forwarded-For" target="_top">X-Forwarded-For header</a>, <code class="literal">XForwardedRemoteAddressResolver</code>.</p><p><code class="literal">XForwardedRemoteAddressResolver</code> has two static constructor methods which take different approaches to security:</p><p><code class="literal">XForwardedRemoteAddressResolver::trustAll</code> returns a <code class="literal">RemoteAddressResolver</code> which always takes the first IP address found in the <code class="literal">X-Forwarded-For</code> header.
|
|
This approach is vulnerable to spoofing, as a malicious client could set an initial value for the <code class="literal">X-Forwarded-For</code> which would be accepted by the resolver.</p><p><code class="literal">XForwardedRemoteAddressResolver::maxTrustedIndex</code> takes an index which correlates to the number of trusted infrastructure running in front of Spring Cloud Gateway.
|
|
If Spring Cloud Gateway is, for example only accessible via HAProxy, then a value of 1 should be used.
|
|
If two hops of trusted infrastructure are required before Spring Cloud Gateway is accessible, then a value of 2 should be used.</p><p>Given the following header value:</p><pre class="screen">X-Forwarded-For: 0.0.0.1, 0.0.0.2, 0.0.0.3</pre><p>The <code class="literal">maxTrustedIndex</code> values below will yield the following remote addresses.</p><div class="informaltable"><table style="border-collapse: collapse;border-top: 0.5pt solid ; border-bottom: 0.5pt solid ; border-left: 0.5pt solid ; border-right: 0.5pt solid ; "><colgroup><col class="col_1"><col class="col_2"></colgroup><thead><tr><th style="border-right: 0.5pt solid ; border-bottom: 0.5pt solid ; " align="left" valign="top"><code class="literal">maxTrustedIndex</code></th><th style="border-bottom: 0.5pt solid ; " align="left" valign="top">result</th></tr></thead><tbody><tr><td style="border-right: 0.5pt solid ; border-bottom: 0.5pt solid ; " align="left" valign="top"><p>[<code class="literal">Integer.MIN_VALUE</code>,0]</p></td><td style="border-bottom: 0.5pt solid ; " align="left" valign="top"><p>(invalid, <code class="literal">IllegalArgumentException</code> during initialization)</p></td></tr><tr><td style="border-right: 0.5pt solid ; border-bottom: 0.5pt solid ; " align="left" valign="top"><p>1</p></td><td style="border-bottom: 0.5pt solid ; " align="left" valign="top"><p>0.0.0.3</p></td></tr><tr><td style="border-right: 0.5pt solid ; border-bottom: 0.5pt solid ; " align="left" valign="top"><p>2</p></td><td style="border-bottom: 0.5pt solid ; " align="left" valign="top"><p>0.0.0.2</p></td></tr><tr><td style="border-right: 0.5pt solid ; border-bottom: 0.5pt solid ; " align="left" valign="top"><p>3</p></td><td style="border-bottom: 0.5pt solid ; " align="left" valign="top"><p>0.0.0.1</p></td></tr><tr><td style="border-right: 0.5pt solid ; " align="left" valign="top"><p>[4, <code class="literal">Integer.MAX_VALUE</code>]</p></td><td style="" align="left" valign="top"><p>0.0.0.1</p></td></tr></tbody></table></div><p><a name="gateway-route-filters" href="#gateway-route-filters"></a>Using Java config:</p><p>GatewayConfig.java</p><pre class="programlisting">RemoteAddressResolver resolver = XForwardedRemoteAddressResolver
