Dear Barney, vgaetera, Eric, anomeome and all who have helped me so far,
If folks check out the tutorial which I authored in the OP - I am well versed and experienced in setting this whole thing up. Specially, with regard to moving Unbound to another port - I followed this guide below :
and this section below states :
Now, you just need to move the existing
dnsmasq server aside, so unbound
can answer your devices DNS queries.
and I do this by following the referenced page ( see below ):
# Move dnsmasq to port 53535 where it will still serve local DNS from DHCP
# Network -> DHCP & DNS -> Advanced Settings -> DNS server port to 53535
uci set 'dhcp.@dnsmasq.port=53535'
# Configure dnsmasq to send a DNS Server DHCP option with its LAN IP
# since it does not do this by default when port is configured.
uci add_list "dhcp.lan.dhcp_option=option:dns-server,$(uci get network.lan.ipaddr)"
uci set 'unbound.@unbound.dhcp_link=dnsmasq'
# Save & Apply (will restart dnsmasq, DNS unreachable until unbound is up)
# Restart (or start) unbound (System -> Startup -> unbound -> Restart)
So, I do appreciate all the help. But if anyone cares to read through the entire guides of mine and / or Torsten's - and offer any advice as to how to get this working on the new OpenWRT snapshots- I will be most grateful. However, I can tell you all ( as I stated earlier ) the setup I wrote up still works flawlessly
on current stable 19.07.6 builds. I am running hnyman's Build for Netgear R7800 - stable openwrt-19.07 owrt1907-r11285 now with absolutely no issues whatsoever. Maybe there are bugs in Unbound with regard to the snapshots. However, I am appreciative to all - have my eyes and ears still open and hopefully in time - I will finally get this working on the snapshots.
What I am ultimately seeking to find out is are there any changes in Unbound 1.13.0-1 ( the current Unbound version in Snapshots ) with regards as to how it needs to be configured so that it will work as detailed in the OP tutorial ?
Peace and God Bless All
