 * To use this macro, simply paste it into your source file (you may also

# Redirect outbound DNS requests to an internal DNS server (for EdgeOS/Vyatta)
# I adapted this configuration from https://old.reddit.com/r/pihole/comments/930g2z/psa_google_services_including_ads_and_others_try/e3t0rqu/?st=jkxfpzdv&sh=370942ba, but I had to make some tweaks, 
# because the config in the comment will cause a massive flood of DNS requests that'll bring down your network if you don't filter destinations appropriately (as I've done below).
