Captive portal blocking ICMP

[Full malito]

Hello everyone,

Since I enabled captive portal on my internal network, the firewall no longer redirects ICMP messages to other interfaces. How can I fix it?
In my LAN interface incoming 'echo-requests' are allowed and there is no floating rules blocking outbound traffic, so I don't know what should I do to solve this problem.

Thank you in advance

What is your pfSense version ?

What your are your captive portal firewall rules ?
What happens when you put in place the rule you've found when you installed pfSense ?
