The first step would be changing your router’s DNS servers to SafeDNS addresses - 220.127.116.11 and 18.104.22.168
Usually, DNS settings change available under the tab "WAN" or "internet" in the network parameters section.
After that, go to SafeDNS Dashboard > Settings > Devices and copy your IP address to the "IP addresses / DynDNS" box, choose a policy, and click "Add".
You have successfully configured your router.
