How else can you install laravel?

Question

Composer

The organization has a terrible bureaucracy with security.
I'm trying to install laravel on the server.
Gave access to the following hosts:

repo.packagist.org 443
repo.packagist.org 80
packagist.org 443
packagist.org 80

github.com 443

As a result connections work through time. When trying to install Laravel, everything crashes.
There are two questions:
1. Are the specified hosts and ports enough?
2. Where does the composer try to download everything from? I understand that there are 3 steps - trying to install from packagist, from api.github.com and from github.com?

PS We cover all IP addresses and hosts as unnecessary. Artifactori we hang inside the LAN and give it access to the outside. We specify the artifactory in the local network to the composer and always knock on the outside only through it.
