Is there a way to change pihole from listing to dns port 53? I want to use my custom port 7502 instead. I tried to use IPTABLES, but it did not work. iptables -t nat -A PREROUTING -p tcp --dport 7502 -j REDIRECT --to-port 53 iptables -t nat -A PREROUTING -p udp --dport 7502 -j REDIRECT --to-port 53
