Ubiquity EdgeMAX Ad Blocking Content Filtering using EdgeRouter

This is based on a guide on the Ubnt forums.

Log into your Edgerouter and run the following - sudo -i && vi /config/user-data/update-adblock-dnsmasq.sh This will switch you to the root user and open up vi.

#!/bin/bash

ad_list_url="http://pgl.yoyo.org/adservers/serverlist.php?hostformat=dnsmasq&showintro=0&mimetype=plaintext"
#The IP address below should point to the IP of your router or to 0.0.0.0
pixelserv_ip="0.0.0.0"
ad_file="/etc/dnsmasq.d/dnsmasq.adlist.conf"
temp_ad_file="/etc/dnsmasq.d/dnsmasq.adlist.conf.tmp"

curl -s $ad_list_url | sed "s/127\.0\.0\.1/$pixelserv_ip/" > $temp_ad_file

if [ -f "$temp_ad_file" ]
then
        #sed -i -e '/www\.favoritesite\.com/d' $temp_ad_file
        mv $temp_ad_file $ad_file
else
        echo "Error building the ad list, please try again."
        exit
fi

/etc/init.d/dnsmasq force-reload

sudo -i
chmod a+x /config/user-data/update-adblock-dnsmasq.sh
sh /config/user-data/update-adblock-dnsmasq.sh
(crontab -l ; echo "56 4 * * 6  /config/user-data/update-adblock-dnsmasq.sh") | crontab -

Thank you for this. I've forked it, and updated it to:

• Include high risk malware domains from DShield. Although many of the domains are already blocked by most browsers.
• Temp files are stored in /tmp and removed afterwards. Reason: any file in /etc/dnsmasq.d/ will be read as a config file (with some exceptions)
• Removing duplicate domains (because of multiple sources)
• Update the blocklists every day instead of once per week

Same here, works very well on a erpoe-5 for a few hours, and then crashes dns forwarder.

Forgive my ignorance but how do I enter the script above in my EdgeRouter X? I've tried the CLI and I guess I'm not doing something right.
