Subject: RealVNC server on RasPi with Raspian/Debian Bookworm - current situation

I know that at one time newer versions of Raspian (eg Bookworm) wouldn't
run RealNVC server because of a problem with Wayland.

Has that situation been resolved yet? Is there a version of RealVNC
server that will work with Debian Bookworm to allow cloud-based
connections from outside my LAN?

I've got RealVNC client (eg on Windows or Android) to connect to my Pi
by Direct connection, but that doesn't help with accessing from the WAN
(eg if my phone or laptop is connected to a different internet
connection when I'm away from home).

The workaround is to use Port Forwarding on my router, to forward <WAN-IP>:<port> to <Pi-LAN-IP>:5900 so an external connection looks like
an internal LAN connection.

However I've got a new internet connection and the company (by default)
uses CGNAT which means that port-forwarding doesn't work.

I may be able to get a static IP address from my internet company which presumably means there is no CGNAT (or at least, no double-NAT) so I can access ports on the WAN address from the outside world and use
port-forwarding to pass on traffic to the Pi on the LAN.

But if that is not possible, I'll need a RealVNC solution that uses a cloud-based connection (as for RealVNC server on Windows) - hence my
initial question.
