This script, courtesy of several people on the forums, who probably should be named, will enable host-based ad blocking via dns.

Maybe this script will not work on every device or it might crash your router when ther is not enough free ram.

Just put this script into "Startup":

#!/bin/sh
logger WAN up script executing
sleep 2
if test ! -s /tmp/dlhosts
then
	cat >/tmp/dlhosts <<"EOF"
logger Downloading http://www.mvps.org/winhelp2002/hosts.txt
wget -O - http://www.mvps.org/winhelp2002/hosts.txt | grep 127.0.0.1 |
	sed '2,$s/127.0.0.1/0.0.0.0/g; s/[[:space:]]*#.*$//g;' |
	grep -v localhost | tr ' ' '\t' |
	tr -s '\t' | tr -d '\015' | sort -u >/tmp/hosts0
grep addn-hosts /tmp/dnsmasq.conf ||
	echo "addn-hosts=/tmp/hosts0" >>/tmp/dnsmasq.conf
logger Restarting dnsmasq
killall dnsmasq
dnsmasq --conf-file=/tmp/dnsmasq.conf
EOF
	chmod 777 /tmp/dlhosts
	/tmp/dlhosts
fi
grep -q '/tmp/dlhosts' /tmp/crontab || 
	echo "45 23 * * 5 root /tmp/dlhosts" >>/tmp/crontab

Enable DNSMasq and Local DNS in Services tab; no Additional DNSMasq options necessary.

Ensure cron is enabled.
