+  * `default` - Exposes user's public and local IPs.  This is the default
+  behavior.  When this policy is used, WebRTC has the right to enumerate all
+  interfaces and bind them to discover public interfaces.
+  * `default_public_interface_only` - Exposes user's public IP, but does not
+  expose user's local IP.  When this policy is used, WebRTC should only use the
+  default route used by http. This doesn't expose any local addresses.
+  * `default_public_and_private_interfaces` - Exposes user's public and local
+  IPs.  When this policy is used, WebRTC should only use the default route used
+  by http. This also exposes the associated default private address. Default
+  route is the route chosen by the OS on a multi-homed endpoint.
+  * `disable_non_proxied_udp` - Does not expose public or local IPs.  When this
+  policy is used, WebRTC should only use TCP to contact peers or servers unless
+  the proxy server supports UDP.
