Ports 443 and 4125 need to be port forwarded from your router to your home server. Port 80 is optional, but is used for the default web site, so if you want that to show - then you also need to forward port 80.
Port 4125 is used for a Remote Desktop Proxy. So once you authenticate with the home server via remote access and then your can access your home PCs that support, and have been configured for, Remote Desktop via port 3389 over your home network. You should not change the firewall settings for port 3389 on your home server and it is not required or even recommended to open port 3389 on your router and forward it to your home server.
