How to forward port 80 on host machine in vagrant?

Question

Vagrant

In the settings file, I write "config.vm.network "forwarded_port", guest: 80, host: 80".
There is an error when running vagrant up.
At the same time, if you separately register port forwarding 80 in the nat settings in virtualbox, then everything works correctly.

Just killed half a day on the same question. In the end, I decided very simply:
You need to open VirtualBox, and then open the "Settings" of the current virtual machine in it:
Press "port forwarding" and then specify 80 -> 80 and others:
That's it!

Note: vagrant does not allow ports below 1024, for its own security reasons.
BUT: they can still be passed through the vagrant config file if the launch is from the superuser. How to do this in the console, I did not figure it out. Nor did I manage to get pfctl's firewall (on OS X) to forward ports.
The VirtualBox GUI seems to have enough rights to open any ports.

I don’t know for sure, but it seems that VirtualBox does not come with Vagrant. The fact that I have it installed is a legacy from the Docker installation.
However, Vagrant uses the same boxes - VirtualBox images. Apparently, therefore, virtual machines launched through Vagrant are visible in VirtualBox.
