help OPNsense FAQ

What hardware can I install OPNsense on?

OPNsense runs on x86-64 hardware, including dedicated appliances and compatible PCs with supported network adapters. It can also run in virtual machines on platforms such as Proxmox, VMware, and Hyper-V.

What is the practical difference between OPNsense and pfSense?

Both are FreeBSD-based firewall platforms descended from the m0n0wall ecosystem, but they have separate interfaces, release processes, and plugin systems. OPNsense is developed by Deciso, while pfSense is maintained by Netgate.

Can OPNsense run WireGuard and OpenVPN?

Does OPNsense include intrusion detection?
