When mapping port 80 of internal IP address 192.168.130.170 to port 10300 of external IP address 183.237.xx.xx, which port should be used when using `karmadactl init -p port --cert-external-ip="183.237.xx.xx" --karmada-apiserver-advertise-address 183.237.xx.xx?How should other clusters register?
when try to use external port

when try to use internal port
Therefore, how should we use karmactl init to initialize in this situation?
