I was quite happy with Brume. I could run Wireguard and AGH at the same time, super simple config. Using oisd blacklist I was getting very few ads and tons of trackers were blocked, even without your choice of browser plugins.
And setup... literally, you could count clicks necessary to set everything up on your one hand. But it ran crazy hot so I returned it while I still could.
One thing I didn't like is that the advanced setup was behind another login and just not handy to use and adjust.
For those that don't know, Brume uses OpenWRT, so I just don't know why it could be made so simple in Brume and so difficult in plain OpenWRT. My HP thin client uses much better CPU and has more RAM than Brume and runs much cooler so to me it was a way to go, at least on paper.
My ISP is not using IPv6, so that is not an issue for me. I want to give it another try.
