Dave details how to set up OPNSense on a miniPC and how to configure it as a transparent filtering bridge. He also sets up IDS (Intrusion Detection System) and IPS (Intrusion Prevention System) via Suricata and deploys the ClamAV antivirus solution on the router.

Any requests to contact me on Telegram, etc, are scams...
Errata: OPNSense is FreeBSD, not Linux!
If you do not have a management interface (third port), don't set the LAN interface IP4 config to None - set a static IP for it so you can still reach it later. Sorry for this oversight!
