Thanks, I forgot all about Fabian integrating that patch 
I don't think so.. or are there easy/complete instructions on how to build Privoxy on a linux box for openwrt? The only time I run a stock version of Privoxy is for a few hours when testing out a new version.
& for what it's worth, my gl.inet mt3000 came in (yay!) I left it with the default OS, installed bind, my RPZ zones and configured the travel router as the only DNS server for everything behind it. It works great as a travel router/ ad blocker.. the only problem is that after some time -- a day, maybe 3, DNS breaks and I need to restart bind So not a perfect solution but it does make watching a "smart" tv tolerable.
I noticed that bind on the mt3000 is 9.18.7 and the current version is 9.18.27
Openwrt is a bit better - it looks like openwrt offers 9.18.19-1 -- so better but not better enough to make me want to switch to openwrt. I opened a feature request for openwrt to update bind. If it does get updated I'd be seriously tempted to try pure openwrt on the mt3000.
