Creating a virtual network using Ubuntu

[tehroonieh MD]

Hello all,

I am new to these forums and to VirtualBox so please forgive my ignorance. I have done quite a bit of searching on Google, but I am not really sure if what I have found really answers my questions, which is why I am here. Basically what I want to do is to create a small virtual network including just 2 users and a host server using Ubuntu for all machines. I am running VirtualBox on a Mac, but I don't really think that should make a difference. I also want to implement a virtual firewall between my users and the host server. This is all to do some virtual firewall testing eventually. I am writing a paper on virtual firewall performance and would like to include some tests in my analysis using VirtualBox. Are there any images of such a set up that are available and if not, does anyone know how I can go about implementing such a scenario? Nothing fancy, just something basic. Any help is greatly appreciated. Thank you!

The only way that VirtualBox would be involved is in providing the network for the virtual machines, and there is nothing complicated about that. All you require is that the three machines are in the same network, and I would simply attach them all to an internal network.

All the rest you would set up in exactly the same way as you would three physical machines connected to the same hub/switch and does not relate to VirtualBox in any way.

I'm sorry, I guess I forgot to mention that the machines are also going to be virtual machines.

I was aware of that. If they were physical machines it is rather more difficult to connect them to virtual networks. Connecting virtual machines to virtual networks is simple and straight-forward. Have you ever done this sort of thing with physical machines? If not, your problem is with networking, not VirtualBox.
