AWS routing between AZs

Question

There's three subnets:

There's one server on subnet A (10.0.1.50) answering to ping performed via Site-to-Site VPN.

Is it somehow possible to route pings to this one and only server also when pinging to 10.0.2.50 or 10.0.3.50?

Why would you want to do that? Looks like an [XY Problem](https://xyproblem.info/) to me... — MLu, Jan 18 '21 at 23:32
