Home Firewall: PC Engines APU2 E2 pfSense and OPNsense build, courtesy of LinITX
I’ve recently been doing some more tinkering with the excellent Raspberry Pi devices, including setting up a home Pi-hole to assist with sending web adverts into a black hole. This got me thinking about implementing a decent home network firewall solution, above and beyond the default one you get when running your average broadband router. Security aside, I’m also a big fan of stats and pretty graphs, and these are quite simply hard to come by with some of the basic consumer broadband router solutions.
Enabling PPPoE with Plusnet – with a modem from 2011
I’ve been looking to implement a more sophisticated firewall solution at home for a while now. The likes of pfSense and OPNsense can happily authenticate with PPPoE via a suitable broadband modem, which takes care of your WAN interface cleanly. If your modem can’t do this, then essentially you have to do it via IP bridging instead, and end up with a horrible ‘double NAT’ situation. I really wanted to avoid that.
