+       };
+
+       key "mykey" {
+               algorithm hmac-md5;
+               secret "yyyyyyyy";
+       };
+
+       view "internal" {
+               match-clients { !external; 10.0.1/24; };
+               server 10.0.1.1 {
+                       /* Deliver notify messages to external view. */
