Ubuntu 24.04 system with a publicly-routable external IP address.

For a given incoming UDP port (<1024, call it port x, I can’t change this), I want to forward that to localhost (or the ens3 interface) on another port (>1024, port y) so I can invoke QEMU as non-root and forward port y to the emulated system’s port x via slirp.

Is this doable?

I’ve tried heaps of nat prerouted examples, but haven’t yet gotten anything to stick.

Boosts appreciated!
