The first step is to disable any features you are not using such as hardware or software firewalls.

Divide your network into smaller segments to increase security and reduce potential attack sites.

Block any unused or undesired protocols as this will harden the security of your router’s firewall.

Enable logging on the router’s firewall to keep a record of all incoming and outgoing requests.

Make sure the router’s firewall is regularly updated to ensure that it is providing the highest level of security possible.
