Prerequisites
The net-nat package requires other network components to be configured.
Router
Your router must be configured to be a NAT that performs port forwarding to your computer. As each router has a different administration UI, you will have to read the guide on your router.
Here's a good article on port forwarding.
Firewall
If your computer has a firewall (for example Windows Defender), you must also configure the firewall to open your local port.
Here's a good article on configuring Windows Defender.
HTTP
If you are forwarding HTTP requests, then on Windows, HTTP.SYS
must be configured to allow incoming requests
on port 80.
