This is the right answer.

The only other solution I can think of would be to put a device in the middle (such as this router).

This is a lot like spray painting a message on a public wall in a neighborhood and then complaining because the community won’t paint over it (or destroy photos they took of it) when you realize how dumb it was.

You’re writing on a public space for free with no business behind it. You’re not the customer in this scenario.
