+title: Configure RBAC in Envoyproxy with whitelist Ip Address
+---
+
+pada tutorial ini bagaimana caranya membuat RBAC di envoy dengan whitelist IP Address yang ditentukan. 
+rbac ini berada pada HTTP-HTTP Filters. dengan menambahkan envoy.filters.http.rbac dengan typed config ```type.googleapis.com/envoy.extensions.filters.http.rbac.v3.RBAC```
+
+
+filter RBAC ini berada di posisi paling atas dibawah HTTP Router. 
+
+
+```bash
+                    name: envoy.filters.http.rbac
+                    typed_config:
+                      "@type": type.googleapis.com/envoy.extensions.filters.http.rbac.v3.RBAC
+                      matcher:
+                        matcher_tree:
+                          input:
+                            name: ip
+                            typed_config:
+                              "@type": type.googleapis.com/envoy.extensions.matching.common_inputs.network.v3.SourceIPInput
+                          custom_match:
+                            name: ip-matcher
+                            typed_config:
+                              "@type": type.googleapis.com/xds.type.matcher.v3.IPMatcher
+                              range_matchers:
+                                - ranges:
+                                  - address_prefix: 10.0.0.0
+                                    prefix_len: 32
+                                  on_match:
+                                    action:
+                                      name: envoy.filters.http.rbac.action
+                                      typed_config:
+                                        "@type": type.googleapis.com/envoy.config.rbac.v3.Action
+                                        name: internal
+                                        action: ALLOW
+                        on_no_match:
+                          action:
+                            name: action
+                            typed_config:
+                              "@type": type.googleapis.com/envoy.config.rbac.v3.Action
+                              name: allow-request
+                              action: DENY
+```
+
+ config filter RBAC ini bersifat global artinya listener yang ditentukan pasti akan terfilter. filtr ini bisa juga menambahkan lebih dari 1 blok IP Address.
