IPTABLES Security Profiles

Hi friends, I would like to configure IPTABLES rules to the configuration of my router, I would like to improve security and make the security of data packets more robust.

I was wondering if there were any rules I could copy and paste compatible with my hardware and network connection.

Disconnect from internet, best decision, security wise.

absolutely, to bad we're no mind readers.

What do you mean? Default iptables configuration blocks incoming connections from WAN port, so it is sufficient for general using. Furthermore you should configure /etc/config/iptables file, and only if not possible in it, use firewall.user file.
