 The most important piece here is having four network cards (ethernet connections), because the whole point of opnSense is to be plugged into all your networks and operate as switch / firewall / gateway for your LAN, WAN and VLANs. The most important piece here is having four network cards (ethernet connections), because the whole point of opnSense is to be plugged into all your networks and operate as switch / firewall / gateway for your LAN, WAN and VLANs.

 +Installing opnSense is quite easy, you should download the VGA edition to boot from an USB thumbdrive, then head onto [[https://opnsense.org/users/get-started/|the installation guide]] to follow the official opnSense guide.
 +
 +As general hints, you must define beforehand which ethernet port you will plug into your home network: this will be called LAN interface, and which ones will be used to connect to your ISPs gateways. The first one will be called WAN and the second one will be called OPT1, OPT2, and so on.
 +
 +You will be able to rename all those interfaces later on, but it will be annoying specially for the LAN one, so i suggest you get it right immediately. I also suggest you set a static IP on the LAN interface, i choose the **10.20.30.254** IP for the opnSense. This will become your gateway and DNS address for your hosts.

 +On the WAN interface, usually you want to set it as DHCP.
