I want to apply a stricter firewall for the guest network 1, to block all UDP traffic, of course basic services traffic like UDP 53 would be allowed, but, redirected to the router itself and answered by the router's own service, not the internet (this means that there is no way to masquerade as legitimate UDP traffic, as invalid requests will be dropped).
Background supplements:
I've recently purchased some IoT devices that I don't trust very much, and I can see them occasionally phoning home using udp, maybe some sort of status check, I'd like to block traffic like that, and reduce the attack surface because I'm very sure, these IoT devices work fine without UDP traffic.
What should I do to achieve it?
