Kali linux virtualbox too small screen3/24/2024 Then, we need to enter the range of IP addresses. Hit enter 3 times to get the screen to configure DHCP service for private LAN.Īs we can see in the above figure, we need to enable DHCP server on LAN interface by typing "Y". We will be prompted for the subnet mask bit count. We will then be prompted for the LAN IP address.Īll these steps explained so far are shown in the above screenshot. This should allow us to configure the private interface, which is le1 (LAN). Since we are going to configure the second interface, we will choose "2" again. Then, we should see the available interfaces. In the above screen, just enter 2 in order to select "Assign Interfaces". To do this, we are going to setup an IP address for the interface le1. Now, we need to configure the other interface, which is private and not directly accessible to the public users. You may look at the network diagram we have shown in the beginning to better understand this. So, we can access this IP address from any computer connected to the same Wi-Fi network. This interface is publicly accessible in our lab. This is shown in the figure below.Īs we can see in the above figure, pfSense is assigned with 192.168.1.106 on the interface le0. The above step creates an IP address for the WAN interface automatically. We should see the following screen asking for the user confirmation to proceed. We can clearly observe in the note in the above figure that the internal network will be behind the NAT.Īfter filling in the required details, hit enter. Then, we will be asked to enter interface names for both adapters we set.įor the WAN interface, specify "le0" and for the LAN interface specify "le1" as shown in the above figure. When it prompts for VLAN setup, just type "n" and hit enter. Leave it for Autoboot and you should see the following screen in a moment. Now, we are done with the VirtualBox settings and we now need to configure pfSense. This should look as shown in the figure below. So choose "Adapter 2" and select "Internal Network". This is going to be the interface for the private network protected by the firewall. Now, we need to setup another interface for pfSense. This is the public facing interface for pfSense. Change "Adapter 1" from "NAT" to "Bridged Adapter". Before that, let us make changes to VirtualBox network settings for our pfSense instance.īy default, Adapter 1 is attached to NAT in Virtual box. The steps to configuring pfSense are shown in the next section. Make sure that pfSense is installed in VirtualBox.Īfter completing the installation process, we can proceed with pfSense configuration. to create more vulnerabilities for an external pentest. We can open ports for other vulnerable services such as FTP, SSH etc. Firewall and the private network can be accessed from users connected to the same network (Wi-Fi router) or from the host machine. Thoughfirewalls cannot be used to stop web attacks, since port 80/443 is opened for obvious reasons. Internal Pentest – Assuming that an attacker has access to the internal network, we can use Kali Linux with the IP address 10.0.0.5 to pentest the other machines in the private network.Įxternal Pentest – Web Server is kept behind the firewall. To avoid this, the Web Server is kept in the private network. Note: If you want to setup a true DMZ environment in this lab, you need to setup back-to-back firewalls. PfSense firewall can be downloaded from the link below. So we won't be covering how to configure Windows Server. The main focus of this lab is to show how we can set up the environment using pfSense. Kali Linux can be downloaded from the link below.Īs mentioned in the beginning of the article, we need to get a licensed version of Windows Server from Microsoft. VirtualBox can be downloaded from the link below. I am using Mac as host machine (192.168.1.103) and am connected to a wireless router (192.168.1.1). Windows Operating Systems that we use in this article must be purchased from Microsoft or you can go with trial versions available.įollowing is the network we are going to setup in this article. Before proceeding further, here is a quick note about licensing.
