Now, instead of using independent `startup` and `shutdown` events, you can define that logic in a single function with `yield` decorated with `@asynccontextmanager` (an async context manager).

For example:

```Python
from contextlib import asynccontextmanager

from fastapi import FastAPI

		{
			name:     "no match",
			sourceIP: "10.0.0.2",
			destIP:   "10.0.0.3",
			destPort: 80,
			output:   "",
		},
		{
			name:     "single endpoint",
			sourceIP: "10.0.0.2",
			destIP:   "172.30.0.41",
			destPort: 80,
			output:   "10.180.0.1:80",
		},
		{
			name:     "multiple endpoints",
			sourceIP: "10.0.0.2",
