Tightening firewall

ICMP is enabled by default on red

On a fresh install, the red interface is responding to ping from the public internet. I must be looking in all the wrong places, because I can’t find the option to disable this. Setting the firewall to drop all ICMP to the red interface isn’t doing it either. How do I get red to ignore ICMP requests coming from the internet?
