Here’s an update. I’ve built Bind 9.20.15 with this patch backported. And installed on OpenWRT. I’ve also build ISC-DHCP with this PR merged:
https://github.com/openwrt/packages/pull/28072 My understanding was that with patch 11314 included, I wouldn’t need: disable-empty-zone 168.192.in-addr.arpa; but it seems I do anyway. Do I need to apply this to a more recent version of Bind? Are there other configuration lines I need to enable it?
