Your current default gateway for your existing 192 network needs to have a route to your 10 network. Otherwise none of your devices in the 192 network know where to go to access the 10 network.

Yea. This is what spanning tree and bpduguard is for. Don’t disable them on your edge.

Setup nginx as a v6 to v4 reverse proxy. Or the inverse if you have a public v4 in a vpc to use as a dmz.

I was looking for this

/usr/lib or /usr/lib64 or /lib (some distros) or /lib64

Some things (like hosts file) are in /etc. /etc mostly contains configs.

Pfsense has an openvpn server and client built in. Also if you are using site-to-site ipsec vpns it can be useful. I think it will also use the extensions if you run a web proxy to inspect tls traffic. If you just use it for a nat gateway, then you don’t need aes-ni or even most of the features Pfsense provides.
