Generic script to create ipsets lists from the free lists available from iblocklist.com with optional whitelisting by domain
For ASUSWRT, place this in /jffs/scripts and make it executable. This script can be called from /jffs/scripts/firewall-start or can be scheduled to be run periodically via cron
For PCs and other routers with ipsets, this should work as well. I've tested it on a CentOS machine
