Remotely access the Apache server installed on the VM from a computer in the local network

This is how I do this on my home network.

On the computer that is actually running Vagrant, edit the Vagrantfile and move the port forward 8088 (or whatever port number you choose) from the host (as you call "Actual Machine") to port 80 on the Guest (as you call it) "VM Running Apache") it).

Do a normal idling and you should see the port forwarding happen on startup. I personally have about 8 virtual hosts running on my Vagrant box, each with their own hostname. I edited the hosts file on the host machine (machine "B" above) to point these hostnames to the ip of the "Vagrant" box. It works just fine, I can put something like mysite.dev in the address bar and the site will start on my local machine.

Now, to make it work on another computer within the same subnet as the host, you will need to edit the hosts file on the second computer. Point the hostname ( mysite.dev for my example ) to the actual IP address of the host. This will forward any instance of mysite.dev to the computer you marked as "B" in your question. The only problem is that this just points to the standard port 80, like any normal web page. You want this traffic to actually reach the machine "A" in your question. So instead of just putting mysite.dev in your browser's address bar, put mysite.dev:8088 (or whatever port number you chose to forward to computer "A" earlier).

Traffic from "C" will now be sent to machine "B" because the hosts file tells it to go there, and the additional ports you add to the address force machine "B" to forward traffic to the port on machine "A" 80 . Machine "A" receives the request and returns the data to machine "B", which then forwards it back to machine "C".

The end result is that machine "C" sees the page returned from machine "A".

Hope to summarize.

Good luck!
