add passt as dependency

- Do not put too many empty newlines in rendered file
- Also write redirect rules in the output chain.  This will allow us to
use the port from the same machine.  Note that redirect does rewrite the
destination to localhost if used on the same machine, so your
application should also listen to localhost
- made the file a bit clearer with better comments
- Add the explicit device if we can for redirects
