You're applying destination change *after* routing. This does not make much
sense to me. rdr-to should be applied on inbound direction, so that packet can
be routed towards the new address.

This is the old FreeBSD syntax, FreeBSD 15 will support the new OpenBSD syntax,
so rdr-to is the preferred way on 15.
