The following topology summarizes this implementation:

Topology implementation
In the following we implement our security topology. First of all with create our instances or machines that will act as the security gateways and the security manager in our virtual environment, virtualbox, then we’ll connect those machines to the network provides by the host (windows) for them to join each other and the network from gn3. As soon as the network is available, the dashboard is ready to connect to those instances, to start the configuration of our SG gateways. We push our fist policy and check on smartview that this policy is in action.
Machines in virtualbox
To implement this architecture we first emulate gateways and manager using Oracle VirtualBox (installed on Windows). In figure we show the 3 emulated VM supporting: SM, SG1 and 2. We used this .iso image to build our VMs: Check_Point_R77.20_T124_Install.Gaia.iso.

Networking for virtualbox machines
Now that we created the virtual machines in virtualbox, will create the equivalent of subnets to connect those machines network interfaces in the correct security zone.
