I have configured AdGuard on my OMV/Portainer using below video tutorial:
On my Asus router - RT-AC85P I set my OMV address IP under LAN/DHCP Server/DNS and WINS settings section in field IP of DNS server (there is one additional field for WINS Server but nothing more (as primary and secondary DNS server IP). Everything else was set as TechnoDadLife said on his video.
On my Windows 10 machine (connected to my router via ethernet cable) ads are blocked very well except ads on YouTube videos and on some webpages, which I am not using anyway - previously I was using AdGuard windows version with paid subscription and it works better than OMV version. Maybe there is a possibility to connect my AdGuard subscription (it is a lifetime subscription for one device) with OMV AdGuard version? Or just use it on my router directly to block all ads on my entire network?
Anyway, blocking ads on my Android devices and LG B8 with webOS (on YouTube) are not working. Please anyone help with that.
