If it is allowed, we will forward to the target destination.

#### Hairpin

In the case that the destination has a waypoint, that waypoint must have been bypassed to reach the inbound passthrough codepath.
How we handle this is [under discussion](https://docs.google.com/document/d/1uM1c3zzoehiijh1ZpZuJ1-SzuVVupenv8r5yuCaFshs/edit#heading=h.dwbqvwmg6ud3).
