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.
I am aware of openwrt and used to use when I used router hardware. I have moved to pfsense. I install it on either a 1 liter mini PC or some other older enterprise piece of hardware.
