Configure Nginx Proxy Manager - noobie questions

Hi all,
I installed the nginx proxy manager on my HA. My public ip is dhcp but my internet provider have ddns and I configured a dns name “myname.provider.com” in the account.
HA is installed on the local network (192.168.10.11:8123).
Now, my first question - which ports do I need to forward on the router side to my HA ?

Thanks
