G-morning,

The opnsense firewall/router was built on an 'old' Mini-PC Intel Atom 1.8GHz 2GB mobo with a Compact Disk of all things but anything with at least 2 nics will be fine. This particular one had 4 nics. I got it for $20 on ebay. Maybe a NUC?

I tried many firewalls and opnsense 'just fit' for me. It puts the /var/logs, etc into ram so it doesn't eat up the file system. It was easy for me to setup.

Yes, OpenWRT can do alot of stuff. I installed a vpn on it so all the traffic going out from it is 'protected' I have been using pihole for many years and love it.

Yes, each layer can do NAT/PAT if needed. I was just showing some possibilities for the OT.

Not to complicate it but I use each section as like a check valve. More protected as it goes deeper. I keep guests and Iot (actually don't use them) at the upper level between the radio modem and the firewall. I don't care what DNS they use or ads they see. My personal network is after the Openwrt router. A poor man's divided network.

See https://www.grc.com/nat/nat.htm

Steve Litt has some good information on his website for a 'straight BSD' firewall. Just make sure the system and var logs go into ram. I kept having issues until I figured that out on the other firewalls.

I am by no means a network guru, just a hobbyist. My original idea was to be able to change ISP without changing anything on my network. I add things a little at a time.

The wife streams her TV, I have security cameras, an NAS (Truenas core 13) on a separate section and everything purrs along at whopping 4.27Mbps from the ISP.

Hope this helps

Cheers!
