Hello,
In the old forum (IPFire Community) somebody posted a dns_blocklist.sh that can consume Pi Hole lists (hosts formats) but is also capable to consume AdBlock lists.
I have used it for many years and I have to say it is more effective than Pi Hole (I stopped using Pi Hole after discovered this).
The source:
Needless to say again, you can use as many input lists as you like: I have added about 10 lists that contains hosts or IP addresses, and another couple being from AdBlock lists ( browser add-on blocking lists)
Hope it helps!
H&M
Late edit: this post Pakfire for DNS Blackholing? - #21 by whypenguinsquint contains more details about several hosts lists used to feed this DNS Blocking script…
Hope it helps!
Late, late edit: I just added Youtube Ads blocking list for Pi Hole to my IP Fire and it works! GitHub - kboghdady/youTube_ads_4_pi-hole: YouTube script to add the new Ads list for Pi-hole
