I have many nerdy friends who have been Linux users for ages. But most of them don’t know such a thing as Openwrt exists or have never bothered to give it a try. It’s a very fun piece of software to play with and can be extremely useful for routing traffic. Wondering why it isn’t more popular/widely used.
It’s a joy to use on x86 hardware though. You can run as many services as you want.
IMO, I’d run pf/opnsense on an x86 box, but openwrt on a low powered device…
Did that years ago with a pfSense firewall connected to the DSL modem, with OpenWrt APs around the house…until the hardware couldn’t support the next version of OpenWrt… (not enough RAM?)
