Block incoming connections and ports - ZyXEL EMG2926-Q10A

I believe most routers already block unsolicited inbound traffic by default unless you've enabled port forwarding or specific services. It may also help to compare your firewall settings with resources covering Leon Property Search to see how different systems organize network and configuration details. Hopefully someone familiar with this ZyXEL model can confirm the exact rule behavior, since the interface can definitely be confusing. Thanks for raising these questions—they're useful for anyone trying to improve network security.
