Hi,
first off, do you know if you actually have a real public address that terminates at your router? Most residential connections don't have a real IPv4 address anymore and you could be behind a carrier grade nat. This would mean that there is not really a chance to be reachable via IPv4. Some providers can switch you to a real address, if you ask them nicely, but I don't know if thats common, or just something that is usual for my corner of the world.
If you have a real address, you would need to configure port forwarding in your router, for the services you want to use. This varies from device to device, so I can't give you a definitive guide.
For example, if you want to host a webserver, you would forward port 80 and 443 to the container that is hosting the 'load balancer' and from there reverse proxy to the different services that you are hosting.
