This works if you haven't defined internal_networks at all, in which case internal and trusted are assumed to be the same. In the general case putting them into trusted_networks only fixes the whitelist rules. If both internal_networks and trusted_networks are defined then forwarding servers should ideally be both trusted and internal.
