Threats to cyber security are constantly changing, therefore having a solid firewall solution is essential to protecting your network. Network security requires a strong firewall, and OPNSense is an excellent choice.Leveraging the advantages of both platforms to improve your network infrastructure, this tutorial will explain to you how to install OPNSense on Proxmox VE 8.x.
What is the OPNSense Firewall?
The FreeBSD-based firewall distribution OPNSense has become extremely common in the cybersecurity community. It is an excellent option for network setups at the home and business levels because it was forked from the pfSense project and was created to provide cutting-edge features and improved security capabilities.OPNSense’s forward caching proxy, traffic shaping, intrusion monitoring, and a straightforward OpenVPN client setup process are some of its primary advantages. OPNSense is a very adaptable and effective firewall solution due to these features as well as the fact that it is open-source.
What is Proxmox VE?
A stable and adaptable environment for hosting virtual machines (VMs) and containers is offered by Proxmox VE, an open-source enterprise virtualization platform based on Debian Linux.Because Proxmox VE enables KVM-based virtual machines (VMs), it’s a great option for hosting OPNSense because it lets you easily include the firewall into your virtualized environment. To further increase the flexibility and control of your OPNSense deployment, Proxmox VE’s software-defined networking (SDN) features let you build and administer virtual networks.An extremely safe and effective network configuration can be achieved by combining Proxmox VE with OPNSense Firewall.
