I am not a firewall guy, you know it
I am wondering what hardware I could use to make a physical firewall. Actually I only have my Livebox that is not really used because all services except the NAT are on a NethServer VM
The first idea could be to find an old PC of course, but I still have many many server/laptop in my room and I was looking to either virtualize it but I am not sure it is really secure, or buy a mini PC pfsense/nethserver compatible.
At the end I would know what hardware I could buy, if you have some clues with some links to evaluate the cost I would be pleased.
