Asuswrt-Merlin-AdGuardHome-Installer:

The Official Installer of AdGuardHome for Asuswrt-Merlin

Requirements:

ARM based ASUS routers that use Asuswrt-Merlin Firmware, and Entware Repository.
JFFS support and enabled.
REQUIRES ENTWARE(!) for package management, and a separate USB drive for storage -i.e. the same drive Entware is stored.
Entware must be fully up-to-date as well opkg update && opkg upgrade.
Minimum recommended to have a 2gb swap file. (up to 10gb can be made with AMTM).
Minimum supported firmware version is 384.11.
It is recommended to use a Router stronger than the RT-AC68U, even though the AdGuardHome can be used at a limited capacity on the RT-AC68U.

Incompatibilities:

Setting Up Your Routers Reverse DNS:

Under Lan DHCP page on Asuswrt-Merlin define a domain such as lan or some-domain like in the image above. <a href="https://ibb.co/vDRpFQh"><img src="https://i.ibb.co/4J3zqY2/Reverse-DNS.jpg" alt="Reverse-DNS" border="0"></a>
Define the appropriate rules inside the Private Reverse DNS Servers. The AdGuardHome Installer already does this, but the information is more for user personal education.

How to report issue:

I need following directories and files:

/opt/etc/AdGuardHome
/opt/sbin/AdGuardHome
/opt/etc/init.d/S99AdGuardHome
/opt/etc/init.d/rc.func.AdGuardHome
/jffs/addons/AdGuardHome.d
/jffs/scripts/init-start
/jffs/scripts/dnsmasq.postconf
/jffs/scripts/services-stop
/jffs/scripts/service-event-end

One can use this command to create a tar archive of these files:

echo .config > exclude-files; tar -cvf AdGuardHome.tar -X exclude-files /opt/etc/AdGuardHome /opt/sbin/AdGuardHome /opt/etc/init.d/S99AdGuardHome /opt/etc/init.d/rc.func.AdGuardHome /jffs/addons/AdGuardHome.d /jffs/scripts/init-start /jffs/scripts/dnsmasq.postconf /jffs/scripts/services-stop /jffs/scripts/service-event-end; rm exclude-files

in current directory and send me the archive for debug. I also need following information:

Which dns server you selected during AdGuardHome installation
Which router you're using
Firmware and its version

How I made this:

Use AdGuardHome binary packages from https://github.com/AdguardTeam/AdGuardHome
I wrote the installer script with stuff inspired from entware-setup.sh from asuswrt-merlin
You can look at all the stuff here https://github.com/jumpsmm7/Asuswrt-Merlin-AdGuardHome-Installer
