Static IP at home for a web server. How to setup? Is port forwarding necessary?

Question

network hardware

Good day!
I connected a static IP through my MGTS provider, now I go on an Internet with a static (white) one. IP
Apparently they registered it in the GPON (router) that they installed in the house.
From GPON, I pulled the wire to my router (wi-fi), 2 devices are already connected from it, a laptop and a computer.
I raised a web server on my computer, made a delegation, registered this static IP in the DNS A-record.
Question. How to get to the site? What needs to be registered in the router settings? Will port forwarding help? I was hoping to get the IP on the computer, and not on the router, it would be less of a hassle ...

Answer 1

In the case of IPv4, on the computer you will receive only the address of the internal network. External on the computer can be obtained if the provider issues IPv6 prefixes. The prefix can be advertised and distributed to any device.
You probably have NAT on your router. On it, you need to forward the necessary ports to the internal address of the server.
