+# Expected values:
+#   String syntax: HOST:CONTROL_PORT, for example: localhost:8888. If
+#   localhost is used then the proxy will only be accessible to clients and
+#   browsers on localhost. Production servers should use a publicly accessible
+#   hostname or IP
+#
+# Firewall Rules:
+#   Control Port: 8888, must be open between Ganeti Web Manager and Proxy
+#   Internal Ports: 12000+ must be open between the Proxy and Ganeti Nodes
+#   External Ports: default is 7000-8000, must be open between Proxy and Client
+#   Flash Policy Server: 843, must open between Proxy and Clients
+VNC_PROXY: "localhost:8888"
