DoS on the "external" internet seems to be 99% overloading the server
CPU that have badly written and bloated server-side scripts. To
protect from this, don't use badly written and bloated server-side
scripts.

Depending on what you use the service for, you can try to rate-limit
everything to something that is just above usable. I suppose this
wouldn't tax your server CPU with unnecessary encryption.
