The only two important columns are “Local address: port” and “process”. The later is what process is listening whille the former is the interface that process is listening on and the port.
So you see that I don’t have any process listening on any port other than 80 and 443 iin the host and the regular ones.
That said, you containers will still listen on the ports you want but only on a virtual network interface.
Basically you only need to publish ports 80 amd 443 on the container or pod you have your reverse proxy on. Other containers need to only be attached to the same network as you already did.
I guess it is better to spend some little time cleaning up your existing install than doing a fresh one. From what you describe, you just have some leftover configuration files you can delete.
Fresh installs is needed when you messed up your current install with broken packages or missing ones or missing configuration and you just don’t know how to clean it up.
So as long as you can clean up your install, just clean it.
