I want an OpenWRT router for my homelab. Before this the only router to my homelab is a meager TPLink Archer, which is really just a plug & play Wifi router with almost no room for customization. The motivation for a router upgrade is mainly feature-wise. I want to install Pihole for my network, but this TPLink router doesn’t give me a reliable method to redirect all DNS traffic to my Pi. I want to use Wireguard to connect into my home from outside, but the router only supports OpenVPN. Ultimately, I want to do port-knocking to keep my network locked out of prying eyes.
