OPNsense provides weekly security upgrades in tiny increments in order to respond to new emerging threats in a timely manner. The project's development is driven by a strong focus on security and code quality. The project has progressed swiftly while still preserving m0n0wall and pfSense characteristics. In 2014, OPNsense was born as a fork of pfSense® and m0n0wall, with the first official release in January 2015. It combines the benefits of open and verifiable sources with the comprehensive feature set of commercial products. OPNsense has almost all of the functions found in pricey commercial firewalls, and in many cases, even more. OPNsense is an open-source, easy-to-use, and easy-to-build firewall and routing platform built on FreeBSD. VirtualBox is continuously developed, with frequent releases, and it has an ever-expanding list of features, supported guest operating systems, and platforms.Īfter giving an overview of Virtualbox let's define the OPNsense. VirtualBox is currently available for Windows, Linux, Macintosh, and Solaris hosts, and it supports a wide range of guest operating systems, including but not limited to Windows. VirtualBox is not only a feature-rich, high-performance product for enterprise customers it is also the only professional solution that is freely available as Open Source Software under the terms of the GNU General Public License (GPL) version VirtualBox is a robust x86 and AMD64/Intel64 virtualization solution that can be used in both the office and at home.

Before we jump on the how-to tasks let’s understand what Virtualbox is and what is OPNSense.

My rule works fine when I change it to apply for all executables.In this tutorial, we are going to explain how to install OPNsense on the VirtualBox environment. However, when running a simple ping or browser on the VM access to the internet is still possible.

I then configure rules to block all protocols and ports for the virtualboxvm.exe for all networks (domain, private, public) both inbound and outbound. I note VirtualBox has several services and processes, and assume virtualboxvm.exe is the process for the running VM (?). I am using Windows 10 and chose to use the Windows Firewall as the configuration can be added to group policy and enforced for all users. That is I have some services on my local network that my VMs must access but I want to block all traffic outside of the local network e.g. I am trying to configure my Windows system such I can block VirtualBox VM traffic to for example the internet but not the local network.
